Wideband Laser Protection Filter (WPF)

One filter blocks all lasers

KiloLambda's Wideband Laser Protection Filter (WPF) is a solid state, free space passive filter, which can limit or switch off the propagating optical power, when the power exceeds a maximal allowed intensity or a damage threshold.

This innovative non-linear filter has high transparency and is only triggered when the threshold power is exceeded.

The WPF is wavelength independent, as such, a single filter can block a wide spectral range of lasers.
