FemtoOptics™ Ultrathin AR-coated Windows

FemtoOptics Ultra-thin Windows offer a number of sizes and thicknesses to help with fine tuning of positive GDD in an ultrafast optical system. Designed for a very broad wavelength range from 620 to 980 nm and an angle of incidence of 0 to 20 degrees, the window comes in 12.7, 25.4 or 30 mm sizes with 0.5 or 1 mm thickness.

Reduced thickness allows for fine tuning of positive GDD
Broad antireflection coating applied to front and back surfaces
Low dispersion, low loss coupling
Choice of 12.7, 25.4 or 30 mm sizes with 0.5 or 1 mm thickness

Features

Minimize GDD

GDD vs wavelength of AR-Coated windows with a thickness of 1 mm (blue) and 0.5 mm (red) at zero degrees angle of incidence, coating code UF.AR1.

The amount of positive GDD of an optical setup can be minimized by employing these ultra thin windows. The broadband antireflection coating applied to the front and back surfaces allows nearly loss-free transmission of sub-10 femtosecond pulses.

Special care and attention should be taken when handling these ultrathin optics. Any small mishap may bring irreparable harm to the window. Handle at your own risk.

Antireflection Coating

Typical residual reflectance vs wavelength of antireflection coated windows at zero degrees angle of incidence, coating code UF.AR1.
