Laser-Driven Light Source

The EQ-77 LDLS is a high brightness source with a broad wavelength range from UV to Visible and into the NIR region.

The unique principle behind the operation of a Laser-Driven Light Source provides extremely bright, spatially and spectrally stable broadband radiation from 170 nm – 2500 nm with a lifetime greater than 10,000 hours.

Based on the highly successful Laser-Driven Light Source (LDLS) technology, the EQ-77 offers the highest radiance and irradiance available in a truly broadband white light source. The EQ-77 features a compact lamp house with clean construction that ensures long life and ultimate stability. 

Researchers using light for imaging and analytical spectroscopy in a variety of applications in the life sciences and materials sciences need light sources capable of providing extreme high brightness and power across a broad wavelength range.
