Laser-Driven Tunable Light Source 

The TLS-EQ-77 is a flexible wavelength tunable device built around Energetiq’s Laser-Driven Light Source (LDLS™) platform. This exciting technology gives the user access to a wide wavelength range of tunability, high spectral resolution and an extremely long lifetime with the added benefit of a convenient fiber-coupled output.

The TLS-EQ-77 offers an extremely long lifetime of 9,000 hours between bulb changes for low cost of ownership. It has high stability, very low noise and is coupled with a precision high-performance monochromator for accurate wavelength selection and repeatable light output across the range of 350 nm-1100 nm.
