Light Sources

Bentham's range of light sources has evolved to suit the requirements of our systems and their users and now offers single, dual or triple sources from 200nm to 20mm.

IL1

The IL1 uses a 100W quartz halogen lamp (150W optional) and a quartz condensing lens to produce a f/4 cone ideal for use at the input of our monochromators.  For stability and output up to 2.5mm this device is unbeatable and is used in many transmission, reflectance and illumination systems.
