Special Polycarbonate (PC) Resin Panlite®

Introduction and Features

Panlite® SP series is a grade developed for optical lenses.

Realizing a high refractive index and low birefringence, it is suitable for making cameras smaller, thinner, and with higher performance.
It also has high heat resistance and is suitable for applications that require long-term reliability.

Target commercial products for Panlite®

Panlite® SP-3810, SP-1516 and SP-5590 are mainly used in the following products.

Lens for smartphone camera
Lens for car-mounted camera
Lens for security camera

Market situation

In addition to the above, it has been adopted for various lenses, and is being developed and studied.
We are also developing new materials from time to time, so please contact us.
