Spherical Plano-Convex Lenses

MATERIALS - Zinc Sulphide (CVD-ZnS)


Crystaltechno Ltd. manufactures spherical plano-convex lenses from fused silica, glass and different types of optical crystals, including CVD-ZnS (Zinc Sulphide).

ZnS (Zinc Sylphide) spherical plano-convex lenses are widely used as focusing transfer optics.

PARAMETER VALUE
 
  Surface form tolerances - Irregularity   Lambda/2 at 633 nm  
  Scratch-Dig   80 - 50  
  Diameter tolerance   +/- 0.1 mm  
  Paraxial Focal Length Tolerance   +/- 2%  
  Centration   less than 5 arc minutes  
  Clear aperture   90 % (80 %, if detail size less 20 mm)  
  Bevels   (0.2-0.5) mm x 45 degrees  


For thin zinc sulphide ZnS plano-convex lenses
Surface form tolerance - without requirements, if ratio of central thickness (tc) to Diameter (D) less 1/10.
