- Many different materials can be processed, such as glass, fused silica, germanium, silicon, other special materials
- Single and compound lenses
- Special know-how in optical cementing
- Lacquered diaphragms, lacquered circumferences
- Special shaping of contours
- High-precision aspherical components, on and off-axis
We supply plano convex and plano concave cylindrical lenses, cylindrical achromats or combined biconvex lenses (spherical radii and cylindrical radii) for many different uses: in projectors and collimators, to correct astigmatism or for the beam expansion and homogenization of laser beams. It is even possible to produce special sizes with a range of CNC-produced contours.
Cylindrical lenses
|
|
- Surface accuracies of λ/8 PV on the cylinder surfaces
- Symmetry errors and axial wedge errors
- up to 2' for larger cylinder radii
