Product Description

General Introduction:
The characteristic of the double convex lens is that the focal length of the middle part of the lens plane is long, and the focal length of the ends of each lens plane is short. Dual convex lenses are mainly used for converging light from point sources or transferring images to other optical systems

Lens Substrates:
N-BK7
Coating Type:

Coating Code:	Coating Type	Wavelength Range
AR.14	Visible Multilayer	430-700 nm
AR.16	NIR Multilayer	650-1000 nm
AR.18	IR Multilayer	1000-1550 nm
AR.33	Laser Line V-Coat Multilayer	1064 nm
-	Uncoated	-

Main Applying:
Relay imaging (physical and real)
Focused divergent beam
Converging beam
Beam expander lens
