High Brightness, Broadband Light Source with Fiber-Coupled Output


Enhanced DUV Performance

The EQ-99X-FC LDLS is a high radiance, broadband light source with integrated collection optics built for systems with fiber connections.

The EQ-99X-FC’s high-performance ellipsoidal collector maintains the ultra-high brightness and spatial stability across the broad spectrum, from 190 nm to 2500 nm, and efficiently couples into small diameter optical fibers.

Proprietary Fiber-Protection Technology™ enhances DUV performance and significantly extends fiber life by reducing the effects of solarization. Utilizing a patented laser-driven bulb technology* and ultra-clean construction, the EQ-99X-FC is ideal for applications requiring ultra-long lamp life and advanced illumination.


Wavelength: 190 nm - 2500 nm
Plasma Size (FWHM)* 100 μm X 180 μm
Numerical Aperture: 0.22 NA
10,000+ Bulb Lifetime
Class 1 (IEC 60825-1: 2014)

Fiber Optic Cable Assemblies

Our proprietary fiber optic cable assemblies must be used with the EQ-99X-FC LDLS. There are two types of fibers available: UV-Vis Solarization Resistant (UV) and Broadband (BB). Both the UV and BB fibers transmit from 190 nm – 2500 nm. However, the UV fibers are constructed using silica with a high concentration of hydroxyl groups (OH) and are engineered to withstand ultraviolet solarization. The UV fibers are ideal for applications benefiting from enhanced radiance from 190 nm – 350 nm and the BB fibers are preferable for applications that benefit from enhanced radiance from 350 nm – 2500 nm.
