Features

FemtoOptics Beamsplitters

These beam splitters are well suited for use with intense pulses with durations of 25 femtoseconds or less. The slightly increased substrate thickness prevents any thermally induced deformation, and carefully chosen coating materials and design yields negligible GDD upon transmission and reflection. Special care should be taken when mounting the beam splitters, since mechanical tension may lead to surface bending.

GDD Graph

GDD vs wavelength for the transmitted beam for beam splitters with a thickness of 3 mm at 45 degrees angle of incidence. The GDD of the coating is negligible both in reflection and transmission. 

Reflectance of 67% Beamsplitter

Typical reflectance vs wavelength of ultra broadband dielectric 67% sub 25 femtosecond beam splitters for an angle of incidence of 45 degrees and p-polarized light.

Coating Code: UF.BS67

Reflectance of 76% Beamsplitter

Typical reflectance vs wavelength of ultra broadband dielectric 76% sub 25 femtosecond beam splitters for an angle of incidence of 45 degrees and p-polarized light.  

Coating Code: UF.BS76

Reflectance of 80% Beamsplitter

Typical reflectance vs wavelength of ultra broadband dielectric 80% sub 25 femtosecond beam splitters for an angle of incidence of 45 degrees and p-polarized light.
