Canon announces camera lens optical element

October 13, 2015 by SPEdit Team

L(25_2015_Canon-announces)1Canon Inc. stated that it has developed a Blue Spectrum Refractive ( BR) optical element that will correct chromatic aberrations in camera lenses to attain superlative image quality. This offering from Canon can substantially refract blue light, which lies within the shortwavelength  range.

The company creates optical elements by assessing organic optical materials, commencing with the design of molecular structures aiming at achieving a chromatic aberration correction that suppresses colour fringing. The BR optical element placed between two glass lens elements will make its first appearance in the EF 35mm f/1.4L II USM wide-angle fixed-focal-length lens, slated for an October 2015 release at a suggested list price of 285,000 yen. By enhancing the barrel structure, ruggedness and vibration shock tolerance have improved. To avoid oil and water splash, the front and rear elements are coated with flouride.
