Optical Achromatic Lens

Products Photos Catalog Optical Achromatic Photos Catalog

Achromatic Lens is an 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.

Supply all kinds of achromatic lens as per your requested.

Specification of our achromatic lens as follow:

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

* Dia.

: +0/ - 0.05

* Center thickness tolerance: +/ - 0.1

* Surface quality: 60- 40 Scrath/ Dig
