Tunable Broadband Light Source for Monochromatic Light


Custom Monochromator, High Spectral Resolution

The TLS-EQ-77-S is a tunable light source optimized to provide monochromatic light across a broad wavelength range.

The TLS-EQ-77-S is built around the EQ-77 Laser-Driven Light Source (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.


Fast wavelength tuning
High spectral resolution
Low noise & high stability
User friendly computer interface
Convenient optical fiber output
Aberration free collection and focusing
