Laser-Driven Light Source 

For applications which require illumination of nanoscale areas, Energetiq’s EQ-99X 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.

The compact EQ-99X is an ultra-high brightness, high stability broadband source that is specifically designed for demanding imaging and spectroscopy applications. The EQ-99X offers excellent spatial and power stability for highly repeatable measurements across the broad spectrum. Utilizing a patented laser-driven bulb technology* the EQ-99X is ideal for applications requiring ultra-long lamp life. The EQ-99X is available with a range of free-space broadband reflective coupling optics to match the ~100µm plasma size to the customers instrument or application. With its high brightness, small plasma, the EQ-99X is particularly well suited to applications using narrow spectrometer slits, small diameter optical fibers or other small étendue optics.
