Optical Bk7 Zf5 Glass Achromatic Lenses Doublets Triplets Glued Cemented - China

price: contact company for price

Achromatic Lenses/ cemented lenses/ glued lenses/ doulets are achromatic

consists of a positive low- index Crown Glass lens element cemented to a

negative high- index Flint Glass lens element. The elements are chosen

so as to cancel chromatic aberration at two well- separated wavelengths,

usually in the blue and red region of the spectrum. Focal length is

constant at those two wavelengths and focal length shifts are virtually

eliminated across the visible wavelengths. One frequent use is to

achieve diffraction limited focusing of a laser beam. Negative Achromats

are typically used when there is a need to eliminate chromatic

aberration. In addition to reducing chromatic aberration at the design

wavelengths, spherical aberration and coma are greatly reduced.

VY Optics Photoelectric Technology Co. , Ltd. Supply all kinds of achromatic lens as per your requested.

* Material: BK7 and ZF2( or according to your request)
