Special surfaces such as toroidal surfaces or spherical reference lenses (TS) can also be manufactured!
Our company can provide the design and production of standard holographic elements (CGH) in a short delivery time and at a low cost. We can manufacture not only aspherical surfaces but also special surfaces such as cylindrical and toroidal surfaces, or as spherical reference lenses (TS). Currently, we are limited to aspheres with a maximum diffraction angle of about 14°, corresponding to NA 0.24 (F/N 2.0). The delivery time can be within 3 months, including the design and production period of the CGH. 【Features】 ■ Capable of manufacturing special surfaces such as cylindrical and toroidal surfaces, as well as spherical reference lenses (TS) ■ Currently limited to aspheres with a maximum diffraction angle of about 14°, corresponding to NA 0.24 (F/N 2.0) ■ Delivery time can be within 3 months, including the design and production period of the CGH *For more details, please refer to the PDF document or feel free to contact us.
