A practical way to generate UV light is by converting more easily obtained infrared or visible laser beams into the UV light using nonlinear optics--harmonic generation processes in crystals. This works well for producing light in nearly all of the UV A range (315 nm – 400 nm), the longest of the UV wavelengths. There are several crystals that can do this job...
Read MoreA perfectly generated wave may be plano or spherical. What happens to it as it travels may alter that perfect shape. This circumstance is called wavefront distortion.
Tight control of crystal growth, sophisticated selection of material, near compulsive attention to detail in manufacturing and polishing combine with discriminating inspection practices to ensure that GAMDAN Optics products are free of transmissive wavefront errors.
