TLS-EQ-77-UV

Laser-Driven Tunable Light Source 

The TLS-EQ-77-UV is a tunable light source optimized to provide monochromatic light in the ultraviolet (UV) wavelength range.


The TLS-EQ-77-UV is built around the EQ-77 LDLS™ and utilizes a customized monochromator that is matched to the optical characteristics of the LDLS. The system includes a software interface that allows rapid selection of output wavelengths and fast scanning between selected wavelengths.

The high radiance of the LDLS allows more light to be efficiently coupled through a narrow monochromator slit. This means that more light flux can be delivered within a narrow bandwidth than is possible with other tunable light sources.

A user-friendly software interface is provided to enable the selection of output wavelengths as well as the scanning speed between selected wavelengths.
