1.591 LENSES

Optical Performance

 The refractive index is approximately 1.591, and the Abbe number is around 40-42. It has a relatively small dispersion coefficient, resulting in minimal chromatic aberration when viewing objects and maintaining high definition. Its light transmittance reaches over 90%, which provides a clear and bright field of vision.

Processing Performance

 It adopts a mature production process with medium cost. The mold pressing method can be used to process the curvature of the lens surface, making it suitable for the production of aspherical lenses. It is also easy to carry out dyeing and coating treatments to meet different usage needs.
