INGENERIC Beam-Shaping Optics
Precision beam-shaping optics for high-power diode lasers
Efficient beam shaping for asymmetric diode laser beams
The INGENERIC beamPROP is a beam transformation system (BTS) made of high-refractive-index glass, designed to specifically adjust the beam parameter product (BPP) of high-power diode lasers. As a precision-manufactured micro-optic array, the beamPROP transforms highly asymmetric laser bar beams into nearly symmetric beam profiles.
This beam transformation is a key prerequisite for the efficient downstream processing of the laser beam—for instance, in the fiber coupling of diode laser bars, free-space collimation, or dense wavelength beam combining (DWBC). By precisely matching the beam parameters of both axes, the beamPROP enables compact, high-performance, and reproducible optical system architectures.
Optimized beam quality and maximum coupling efficiency
Diode laser bars emit beams with widely differing divergence in the fast and slow axes. This asymmetry significantly limits the efficiency of downstream optics. Acting as a beam transformation system, the beamPROP specifically compensates for these differences, laying the foundation for significantly improved beam quality and coupling efficiency.

How is the price for INGENERIC products calculated?
Standard products: We offer standard price lists from 10 pieces up to large quantities.The higher the number of pieces, the cheaper the unit price. Packaging costs are usually included in the product price; the customer bears the delivery costs.
Customer-specific products/custom-made products: For our manufacturing process, precision molding, we need a tool (or several molds/inserts in series production), which incurs one-off initial costs. Product prices are calculated depending on quantity. The higher the number of pieces, the cheaper the unit price. The development costs depend on the complexity and size of the shapes. Smaller shapes can often be realized more cost-effectively, especially in the prototype or sample phase.In the phase up to series production, product prices can often be reduced through scaling. The one-time development costs also cover maintenance and replacement (if necessary).
