ILD-Xe-QH Xenon Quartz Halogen Dual Light Source

xenon quartz halogen dual light source

The ILD-XE-QH is a general purpose broad-band illuminator spanning the spectral range 250-2500nm.

Housing a 75W short-arc xenon lamp and a 100W quartz halogen lamp with automated selection between the two, the ILD-XE-QH can be mounted to the entrance slit of any Bentham monochromator or spectrometer.

Efficient coupling is ensured by using the QH condenser lens and Xe lamp off-axis elliptical reflector to match the monochromator f/#.

Options

Optical chopper Integrated 20-slot optical chopper at exit of source to modulate light level at frequencies from 50-2000Hz. Required in applications in infrared and in measurements performed in presence of secondary/ambient illumination.
Arrestable optical chopper Arrest feature added to above, compromising electromagnet to stop optical chopper at open location to allow CW measurements.
HF-LF chopper Stepping-motor-driven chopper included alongside (arrestable) optical chopper to perform effective low frequency measurements.
Quick-change adaptor Dove-tail interface plate to attach to monochromator entrance slit for ease of changing light sources.
