Partial Reflection Mirrors


Laser beam splitting or combining at a specific ratio might be a tricky part of laser research. OPTOMAN will help you choose the right set of features of a beam splitter or combiner matching your needs the best. We can optimize coatings for laser line or broadband performance, s-pol or p-pol components, ultrashort pulses or CW applications, highest LIDT, or splitting tolerance. Note that we are not limited to a 45° angle of incidence or 50:50 splitting ratio. A wide range of ratios can be achieved via different designs of the dielectric coating.


Broadband, single or multi wavelength performance

Our beamsplitters can be designed for a specific wavelength or wavelengths and can be designed to split or combine laser beams operating in the visible through infrared wavelengths.

20:80, 30:70, 40:60, 33:67, 1:99 or any other specific splitting ratio

A wide range of high accuracy splitting ratios can be achieved via different designs of the dielectric coatings. 

Low GDD behavior for ultrafast applications

Ultrafast beamsplitters feature negligible GDD, both in reflection and transmission.

Slight wedge eliminates internal fringes

A slight wedge causes unwanted reflections from the second surface to be deflected from the optical path.

Optimization for specific state of light polarization

For an optimal result, design optimization for a specific state of light polarization is critical. Partial reflectors can be optimized for an s or p state of polarization, as well as circular polarization.
