Product Description

General Introduction:
Lithium fluoride crystals show excellent transmittance in the ultraviolet region of vacuum. It is used for Windows, prisms and lenses of visible light and infrared 0.104μm to 7μm. Lithium fluoride crystals are sensitive to thermal shock and are affected by atmospheric water molecules at 400°C.

Lens Substrates:

Optional I:	LiF substrate(Lithium fluoride) from CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,ETC
Optional II:	Equivalent (LiF substrate(Lithium fluoride) Made in China, C-laser own brands

Advantages of uncoated lens
Uncoated lenses are used in optical systems and equipment, mainly because they have a very wide wavelength range, high damage threshold ratio, and do not need to be coated, so they are always cheaper than coated lenses. In addition, the uncoated lens makes the image in the camera look more "retro", which is becoming more and more popular in cinema film production.

Main Applying:

Applying Fields I:	Femtosecond infrared pulse
Applying Fields II:	Focus, collect and collimate light Focusing and collimating laser beam Collimating the optical fiber output
Applying Fields III:	Other
