On May 30, INGENERIC laid the foundation stone for their new company building in Baesweiler, Germany. The new building is the company“s response to the constantly increasing volume of orders from customers all over the world. The building, which is scheduled to be completed by the end of 2019, will provide space for all of the approx. 80 employees with reserves for further expansion.

INGENERIC has been based in the Technology Centre AGIT in Aachen since its foundation in 2001, and in 2015 they already outsourced some capacities to Baesweiler, about 20 km away. Growth over the years is such that the company now requires its own building. The move away from the Technologiezentrum is a logical step.

The new production hall in the immediate vicinity of a former colliery covers a gross area of around 2,700 m². The hall will provide around 800 m² of clean room space for the production and finishing of optical elements along with the assembly of optical modules and laser systems. There is also around 600 m² for air-conditioned processing space for ultra-precision manufacturing, where temperatures are partially controlled to within +/-0.5° C. The attached office building for development, sales and administration will offer more than 1,000 m² gross floor space.

With a good 10,000 m² of space, the site offers the potential for further expansion.

Dr. Olaf Ruebenach, co-founder and one of the two managing directors of INGENERIC, sees clear advantages at the Baesweiler site in the Aachen technology region: „The new building and its infrastructure exactly meet our requirements for the efficient production of ultra-precision optics. Not only will we have enough space for the current production volume, we can also continue to expand. Micro-optics is one of the major pace-setting technologies of the 21st century, and we expect significant growth rates.“

Planning and construction of the building are being carried out in cooperation with TRUMPF GmbH Co. KG which, as the parent company of INGENERIC, is also the builder-owner. The building should be ready for occupancy by the end of 2019.

About INGENERIC

Founded in 2001 in the university-city of Aachen, Germany, INGENERIC GmbH develops and manufactures high-precision micro-optic components for high-power applications, along with optical and laser systems including fiber couplers, homogenizers and collimation modules for science, medicine and measurement technology.

Today, INGENERIC is one of the few manufacturers in Europe to develop and manufacture glass micro-optics for beam shaping in semiconductor diode lasers according to the individual specifications of its international customers. The company handles the entire process chain from the lens design and the development of prototypes through to the small-batch production and serial manufacture.

INGENERIC also produces high-power laser systems. For the HiLASE or XFEL project, for example, INGENERIC supplied a number of high-energy lasers delivering 10 pulses per second with an energy of 250 Joules, an average power output of 2.5 kW, and an extremely homogeneous top-hat beam profile with an amplitude contrast of less than 7%.

Background: Precision in detail

One of several fields of application is the production of microlens arrays with structures typically in the sub-millimeter range; their dimensional accuracy is sub-micrometer at less than 250 nm. This makes it possible to produce arrays with high filling factors and to make the best possible use of the optically effective surface area: INGENERIC reliably implements transition zones of less than 10 μm. The benefit to the user: Optimal beam shaping and high-efficiency transmission and coupling.

High-precision molding maintains an offset between the upper and lower sides of the array of less than 5 μm. Pitch accuracy is also very high: INGENERIC reproduces the separation between the individual lens center points with an accuracy of better than 2 μm over a length of 25 mm, so there is no accumulation of errors across the width of the array.

For some micro-optics-particularly the two-sided structures-the exact adherence to the central thickness is vitally important, since they have a telescopic effect and the slightest deviations lead to aberrations. INGENERIC achieves accuracies close to +/-6 μm here.

Compared to conventional methods like quartz etching, INGENERIC achieves a relative radius tolerance better than 0.2 percent, which in serial production is precisely reproducible from wafer to wafer.

Premiere at TUBE/WIRE: Inline geometry measurements pay off quickly, also for production lines with low throughput

Measuring systems for wire rolling and drawing

Premiere at TUBE/WIRE:  Inline geometry measurements pay off quickly, also for production lines with low throughput

CONTOUR CHECK WIRE systems are available with several measuring axes for contour measurements.

At TUBE/WIRE 2018, LAP is going to introduce its new optical measuring system CONTOUR CHECK WIRE. This high-precision system is particularly suitable for inline geometry measurements in production lines with low production volumes. It enables wire producers to comply exactly with the tolerances specified by their customers, while optimizing material use.

In wire rolling mills and wire drawing shops, multi-axes LAP systems have long become established for diameter and contour measurements. In these applications, the systems are often exposed to extremely harsh operating conditions.

LAP has developed a new product line, CONTOUR CHECK WIRE, for geometry measurements in process stages with less challenging ambient conditions.

In many forming stages, one-axis inline measurements of the diameter of the cold wire already help to achieve significant improvements in the quality of the finished product and in the efficiency of production.

Being a moderate investment and an easy-to-use system, CONTOUR CHECK WIRE is a highly attractive option for factories with lower throughputs. The systems measure the diameter and ovality with exactly the same precision as the systems of LAP“s proven CONTOUR CHECK family, yet are smaller and, apart from power, need no other media supply.

CONTOUR CHECK WIRE systems are designed for inline measurements of wire with diameters between 0.5 and 30 mm. They measure with a precision of +/- 8 µm. If operated at temperatures not exceeding 40 °C, they do not require any cooling.

The compactness of the hardware allows the sensor units to be easily integrated into existing lines or used as mobile units at several positions within a factory. Like all LAP systems, they are designed for harsh steel mill environments. They are made to reliably operate under the conditions typically found in rolling mills, they come with a sturdy housing and are ready to use in virtually no time.

For Dr. Ralph Föhr, head of LAP“s Business Unit „Industry Systems“, it was very important to develop a system that could be sold at an affordable price: „Customers using the new CONTOUR CHECK WIRE system can save between 50,000 to 200,000 euros on material and production costs yearly. As the systems cost much less than the amounts saved, the return on investment occurs very fast, especially in factories operating several lines.“

The measured values are displayed both numerically and graphically on the touch screen of the Panel PC that comes with the system. Integration into the factory infrastructure is possible via optional interfaces.

Background information: The CONTOUR CHECK family

The new systems are based on LAP“s CONTOUR CHECK family of products which measure diameters and contours of long products in the metals industry, for example, of wire, bars, sections and tubes. Depending on the complexity of a product, they may measure the contour in several axes, either with METIS laser scanners or with the light-sectioning method.

During the last 25 years, LAP has installed more than 300 laser-optical contour measuring systems at customers in the steel industry.

New INGENERIC microlens arrays offer significant advantages in optical applications

Micro-optics for beam shaping, collimation, and homogenization: Highest precision molding of high refractive index glass

New INGENERIC microlens arrays offer significant advantages in optical applications

Single-sided microlens array with 400 lens elements and square aperture, two-dimensional

INGENERIC premiers their new microlens arrays with high refractive index glass at this year’s „Laser – World of Photonics“. Manufactured in a precision glass molding process, they are characterized by high dimensional accuracy. INGENERIC develops customized arrays and brings them to commercial serial production.

At the trade fair, the company based in Aachen, Germany is presenting its new microlens arrays with up to 500 individual lenses and dimensions of up to 60 x 60 mm, for example for beam shaping and light homogenization.

INGENERIC works with precision molding techniques, which ensure that high refractive index glass takes on precisely the form of the molding tool. The molds manufactured by the company to sub-micron precision enable the arrays to be produced with exceptionally high accuracy and reproducibility. INGENERIC successfully manufactures arrays with minimal transition zones, highest filling factors and minimal pitch errors, even in large batches.

When it comes to designing micro-optics for special applications, the process offers significant degrees of freedom: Compared to the etching process, optics can be far more complex with a larger radius-to-aperture aspect ratio. Furthermore, the process excels with a relative radius tolerance better than 0.2 %, which is fully reproducible in serial production.

Dr. Stefan Hambücker, a Managing Director at INGENERIC, sees clear advantages for his customers: „As one of the very few European manufacturers involved in the development and manufacture of the new microlens arrays with high-refraction glass, we are not only opening up new markets to our customers. We also help them to improve their existing systems. They can improve the quality of their products while at the same time they meet the cost requirements of serial production.“

INGENERIC manufactures microlens arrays with aspherical or spherical lenses that are planoconvex, biconvex or convex-concave, and which have a circular or rectangular aperture measuring from 0.2 to 3.0 mm. They can have dimensions of up to 60 60 mm.

Beam-shaping lens beamPROP

Along with its standard portfolio, INGENERIC is also exhibiting its new beam-shaping optic beamPROP 200 at the fair. It is a key component for fiber coupling the laser light from diode bars and for dense wavelength beam combining. INGENERIC has now reduced the pitch from 500 and 400 to 200 μm, which expands its geometry spectrum for use with additional laser bars.

The beamPROP from INGENERIC enables customers to achieve significantly better and more reproducible results than with components manufactured in other ways. INGENERIC can leverage the expertise from its tried-and-tested production technologies for the manufacture of the new beamPROP; a precise and automated assembly technology is applied here.

The advantages of INGENERIC beam-shaping optics over other manufacturing processes include:
-Optimal use of the aperture due to the smallest possible transition zones and particularly high filling factors
-Minimal aberration due to manufacturing accuracy
-Precise beam rotation thanks to the high accuracy of the lens center thickness of +/- 6μm
-Minimal pointing errors due to the precise alignment of the front and back of the lenses
