Fused quartz biconvex lens

Calcium fluoride Caf2 biconvex lens
  • Quartz biconvex lens is very suitable for many limited imaging applications. The biconvex lens is convex spherical with the front and rear surfaces, and the radius of curvature is equal, which makes the lens symmetrical, makes the spherical aberration small, and eliminates the coma and distortion.
  • Quartz biconvex spherical mirror has good transmittance from ultraviolet to near infrared (190-2200nm). Quartz material is a common optical glass for preparing optical elements
