B-270

 

B-270 is a commercially available material that has excellent optical transmission. The material comes in drawn form in a variety of thickness & sheet sizes, and the drawn surfaces can be polished to improve the optical performance. Most sheet sizes are about 35"* 66"Contact one of our Application Engineers for further information.


Applications:

 

Optical substrates, glazing, image-forming optics, electronics, laboratory and coating substrates. Flatness, parallelism, cutting tolerances, roughness, cosmetic defects and visual inspection all conform to the specifications.
