Collimating lens (grin lens) is mainly suitable for connection of beam divergence, it is usually used in optical passive components connection between optical fiber and optical fiber.
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.
applications
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.
