IR Cut Filter (Cold Filter) - MF-CLD127S

MF-CLD127S - IR Cut Filter (Cold Filter)

IR cut filter (cold fiter) transmit visible rays and cut IR rays With high transparency (achieved with dielectric multilayer vapor deposition coating) it enables to capture high contrast gel documentation image by eliminating background glow or it can protects polarizer from the heat exposure when placed in front of a 3D projector.

Characteristics

■ High transmittance and transparency. ■ Equal transmittance level across the entire visible ray spectrum. Optical white glass prevents color bias. ■ High precision and high quality vapor deposition glass. No deposition unevenness. ■ Ground glass provides less image distortion compare to old models.

Usage Example

■ 3D Projection - Protect polarizers from heat generated from 3D projector. ■ Gel Documentation - Eliminate background glow caused by UV transilluminator

Thermal control effectiveness of IR filter	Test Condition
Polarizer is deteriorated by thermal heat. IR cut filter prevents it by suppressing heat.	Light Source ： 250W halogen lamp Light to polarizer distance ： fixted at 80mm Cold filter placed in between light & polarizer Room temperature ： 23℃ Measure center of polarizer every 60 sec. * measured value and not guaranteed value
