Data sheet Hybrid Cube Half Mirror 20x20mm Wavelength 400 - 700nm

Description

Low polarizing cube half mirrors can be used for broadband visible and infrared light. Cubes are applicable for use in polarizing systems and lasers with multiple wavelength or visible light.

This hybrid coating is a special combination of metallic and dielectric multi-layers that result in low polarizing and broadband coating.

As it is cube shaped, there will not be any lateral shift of the optical axis when a normal incident beam is applied. During transmission and reflection of lights, the aperture remains unchanged.

Even when the orientation of linear polarization has been changed, beams are equally divided as reflected (R) : transmitted (T) (ratio is 1:1)
% Transmission R:T = 1:1 - T = 45 ± 10%
Coating metallic and dielectric + AR
Dimensions Side 20 mm
Scratch-Dig (S/D) 40/20
Spectral range 400 - 700 nm
