technical data
Grin lens materials include UV fused silica, BK2 glass, IR calcium fluoride, zinc selenide, etc. Zinc selenide and calcium fluoride lens, which have low group velocity dispersion, can be used for infrared ultra-short pulse collimation.
Aitmont optical has launched a new dynamic focusing ZVM lens, which USES an internal liquid lens with a main magnification rate of 0.65-4.6x and can achieve seamless focusing within a range of 7X.
