Non-polarizing Plate Beamsplitters


Cemented cube beamsplitters fail in most of high power laser applications due to epoxy layer and hybrid origin of coatings, where chromium or other types of metals are used. OPTOMAN introduces all dielectric Non-Polarizing Plate Beamsplitter, which is virtually insensitive to the polarization of the incoming beam.


S and P polarization components matched to within 5%

With 5% being typical tolerance, OPTOMAN can match S and P components to within 1% for most demanding applications.

Back surface AR coated to eliminate ghosting

Front surface is coated with multilayer all dielectric coating while the back face is coated with anti-reflective coating to minimize reflection losses and eliminate ghost images. 

30 arcmin wedge eliminates unwanted internal fringes

Slight wedge helps to eliminate back reflection to the laser and unwanted interference fringes, which might appear in the image.

High Laser Damage Threshold

Non-polarizing beamsplitter coating is all dielectric coating and it features laser damage threshold much higher than hybrid metallic-dielectric non-polarizing beamspliter cubes, for example >10 J/cm2 @ 1064 nm, 20 ns, 20 Hz.
