LS-475-Pulsed Blue LED Light Source

The LS-475 Blue LED Light Source produces pulsed or continuous spectral output centered at 475 nm. The LS-475 is designed as an excitation source for fluorescence measurements.

Use the LS-475 with one of our preconfigured fluorescence spectrometers. In addition, we have several sampling accessories for fluorescence applications.

LS-475 Features

High Stability. Better than +/-1.0% drift after 2-minute warm-up time
Fan-cooled. Minimizes light source drift
Filter Slot. Accepts filters for attenuating or redirecting energy

The LS-475 is $915.

Also available is the LS-450, a 470-nm wavelength LED with a housing that will accept LED bulbs ranging from 380 nm to 640 nm.

The LS-475 provides a very stable output and keeps cool with a built-in fan. It has an SMA 905 Connector for coupling to optical fiber assemblies and a filter slot that accepts 25.4-mm round or 50.8-mm square filters up to 3-mm thick. An 800 mA, 12 VDC power supply comes with the unit.
