Energy measuring heads for built-in into lasers

These measuring heads are made up for high sensitivity and a high repetition rate. The windowless build-up and the used metallic absorbing layer allows a usage up to the UV-range.
If necessary (e.g. The usage at different wavelength) we will coating these sensors with our proven broadband absobing black layer too.
