Laser-Driven Tunable Light Sources Series EQ-77-S /EQ-77-UV /EQ-77-NIR

Built around our Laser-Driven Light Source (LDLS®) technology, the Laser-Driven Tunable Light Source (LDTLS®) gives you access to a wide wavelength range of tunability, high spectral resolution, and an extremely long lifetime with the convenience of fiber-coupled output.

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 Scanning, Quick Output Wavelength Selection, and Custom Monochromator

TLS-EQ-77-UV tunable light source provides monochromatic light in the ultraviolet (UV) wavelength range.

The TLS-EQ-77-UV 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.

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.
