CR39 LENSES

Optical Performance

 The refractive index is approximately 1.499-1.5, and the Abbe number can reach 58-59. It has a small dispersion coefficient, resulting in almost no chromatic aberration when viewing objects, high clarity, and a light transmittance of 92%, which provides a clear and bright field of vision.

Processing Performance

 The production process is mature with low cost. It can adopt mold pressing to process the curvature of the lens surface, which is suitable for the production of aspherical lenses. It is also easy to perform dyeing and coating treatments.
