Spherical lens provides planar, concave and
convex structure. They are widely used in security, vehicle, digital camera,
laser, optical instrument and other fields.
Fluoride optical crystal products include
calcium fluoride (CaF2), barium fluoride (BaF2), lithium fluoride (LiF) and
other alkaline earth metal ion fluoride crystals. The range of transmittance of
this series of crystals is 0.11~12.5 um, which makess them excellent
ultraviolet and infrared optical materials. They are widely used as infrared
window, optical lens, prism, wave plate, objective lens and other optical
applications.
Calcium fluoride (CaF2) has good mechanical
strength and moisture resistance, and it has a high transmittance in the band
0.13um~11um. It is used in laser, infrared, ultraviolet and high-energy
detection fields. It is also a high-quality material for making optical
components such as optical prism, lens and window. Its operating temperature
under atmospheric pressure can reach 600℃, vacuum drying can reach 800℃. Barium
fluoride (BaF2) is widely used in infrared window, ultraviolet window and
prism. Lithium fluoride (LiF) is the material with the best transmittance in
the vacuum ultraviolet region, and it is widely used to manufacture optical
Windows, lenses, prisms and refraction elements in the UV-visible-infrared
field.
