A compact UV/Vis and (optional) IR LED source for coupling to a fiber optic using a built-in SMA905 (or an FC-PC) adapter can be used for a wide range of spectroscopy measurements. It provides stable optical power illumination for various applications including absorbance, reflectance, and transmission. Unlike traditional short-arc sources with deuterium, xenon or mercury-xenon bulbs, this phosphor-converted full spectrum SMA LED (pcLED-FS-SMA) source is built using advanced solid-state lighting technologies involving UVC LEDs and UV/Vis phosphors. The pcLED-FS-SMA is a compact DC-powered source that covers the spectral range from 260nm to 850nm with an optional IR source. It can be supplied with or without a heat sink and driver electronics with cooling and enclosure. The heat sink built-in cooling fan helps achieve highly stable output and to protect the LED from thermal damage while minimizing phosphor thermal quenching.

Heat Sink Option for High Power UV/Vis LEDs

A broadband UV/Vis LED source is ideal for compact and portable optical absorbance, reflectance, and transmission measurements.  It consumes significantly less electrical power and generates less heat and more optical output compared to traditional UV/Vis sources. Typical UV/Vis sources used in spectroscopy (deuterium lamp, for example) can consume around 25W while producing less than 1mW of optical power. This UV/Vis LED source consumes 1-3W (depending on configuration) while delivering several mW of optical power. With such a small footprint, it can be integrated into a wide range of optical equipment or be used as part of a detector calibration system. It can be powered and even pulsed using a wide range of power sources. The device can also function as a “white light” spectroscopy source with high color rendition (CRI>90) and around 4000K color temperature. It can therefore be also used for a wide range of photo metric testing, as shown below.
