  • Optical Achromatic Lens - China

    price: contact company for price

    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

    * Surface figure: 0.5- 0.2

    * Centration < 3arc min

    * Chamfer: 0.1- 0.25* 45 degrees

    * Design wavelength: 486.1mm, 587.6mm, 656.3mm

    ( the parameter is demision of nomal lens, so specification will be changed according to different demision and material)
