Thorlabs' High-Power Light Sources are solid-state plasma light sources (LIFI®) that combine the best features of solid-state electronics and full spectrum plasma emitters. The HPLS series uses a dielectric resonant cavity to efficiently couple power from a solid-state power amplifier into a high-intensity discharge vessel unlike other electrodeless sources. The results are a long life (>10,000 hours**) and a complete color spectrum, making this source ideal for applications such as endoscopy, microscopy, and other medical lighting and inspection applications. This unit also offers many additional features including a USB 2.0 control interface and instantaneous intensity dimming.

At the heart of LIFI® is the bulb sub-assembly where a sealed bulb is embedded in a dielectric material. This design is more reliable than conventional light sources that insert degradable electrodes into the bulb. The dielectric material serves two purposes: first as a waveguide for the RF energy transmitted by the RF Power Amplifier Circuit (PA) and second as an electric field concentrator that focuses energy in the bulb. The energy from the electric field rapidly heats the material in the bulb to a plasma state that emits light of high intensity and full spectrum.

**Note: The lifetime of >10,000 hours is specified for use at 50% of the original output.
