Laser-Driven Light Source

The EQ-400 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-400 offers the highest radiance and irradiance available in a truly broadband white light source. The EQ-400 features a compact lamp house, with clean construction that ensures long life and ultimate stability. With a 170 nm-2500 nm wavelength range, and a choice of source dual-beam output or a single-beam output with retro-reflector, the EQ-400 is flexible for a broad variety of applications.
