Product Description

 

Acromatic Lens

  • Designed for 0° Angle of Incidence
  • Less Than 1.75% Reflectance Per Surface @ 400 - 700nm
  • VIS 0° and VIS-NIR Coated Achromats Also Available

Achromatic lenses are very common type of viewer lenses,they consist of two or more lense elements,which have been corrected for chromatic aberration with respect to two selected wavelengths,the elements must be fixed in relation to one another by either mounting or cement.
Achromatic lenses are designed to specifically function within the infrared,visible,or ultra-violet wavelength ranges.
