Interference-filter based wavelength selection and the cateye configuration revolutionized space atomic clocks.

IDEA, the latest master laser from LEOS, implements this proven technology in a rugged mechanical assembly to provide reliability, spectral purity and ease of use to your laser-based measurements.

The spectral coverage spans almost continuously from 630nm to 1400nm.
