Features

High Damage Threshold

The typical damage threshold for this beam splitter is 5.0 J/cm2 with 10 nsec pulses at 1064 nm

3 mm Thick Fused Silica Substrate

Constructed of durable fused silica, the front surface of the thin 3 mm thickness substrate is coated with an ultrafast optimized beamsplitter coating and the back side coated with an AR coating. This dichroic filter will easily satisfy the need for ultrafast beam harmonics separation.

Reflectance Outside the Design Wavelengths

Reflection and transmission at wavelengths other than the specified wavelengths are uncontrolled and can vary significantly from the curve shown. Use of beamsplitters outside the design wavelengths is not recommended.
