Compact, Economical, High Brightness Broadband Light Source


Illuminate Nanoscale Areas

The EQ-99X LDLS is an ultra-high brightness, high stability broadband source perfectly suited for small etendue optics.

Designed for demanding imaging and spectroscopy applications, the EQ-99X offers excellent spatial and power stability for 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 ~100 µm plasma size to your 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 etendue optics.
