Product Details

  • Designed for 0° Angle of Incidence
  • Less Than 0.25% Reflectance Per Surface @ 880nm
  • MgF2 and VIS 0° Coated Achromats Also Available

TECHSPEC® VIS-NIR Coated Achromatic Lenses consist of two optical components cemented together to form an achromatic doublet. The doublet is computer optimized to correct for on-axis spherical and chromatic aberrations. TECHSPEC® VIS-NIR Coated Achromatic Lenses have visible/near-infrared broadband anti-reflection coating, which is specially optimized to yield maximum transmission (>99%) in the near-infrared. The achromatic lenses reduce reflection to less than 0.25 percent per surface at 880nm. Magnesium Fluoride coated and VIS 0° coated achromats are also available.

Technical Information

Coating Curves

  • VIS-NIR (400-1000nm)
Only 2 different Y Axises can be displayed at one time.

Please note that coating performance outside each product’s specified design range is theoretical and may vary.
