Hybrid Cube Half Mirrors
HBCH
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.
Optics & Optical Coatings
- This hybrid coating is a special combination of metallic and dielectric multi-layers that result in low polarizing and broad- band 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)
