TLS-EQ-77-NIR

Laser-Driven Tunable Light Source 

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


The TLS-EQ-77-NIR 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.
