Compact sources

These sources can be used with single core multimode fibre optics, for optical and spectroscopic sensing or by themselves for other general applications. Included are deuterium, halogen and pulsed xenon to cover, the ultra violet, visible and  near infra red spectral regions.

Lamp housings

Available for high power lamps from 75watt  to I KW. These are available for xenon, xenon mercury, large halogen and other lamps and have single or multiple optical ports. A range of  lamp power supplies can be provided.

Arc lamp sources

Have a BALANCED spectral light output which is important for large wavelength range spectral measurements This source is used with fiber optics, which are solarised for use below 230 nm.

Deuterium and halogen sources

Up to 200 watts complete with housing and power supply. Also available with monochromators, shutters and fiber optic light delivery. Suitable for applications including fluorescence, photo-irradiation and spectroscopy.


LED Sources

Compact LED sources for use with fibre optics and covering the UV, Visible and NIR spectral regions are operated  with modulated or stabilised continuous output.

DC950H Machine vision illuminator;
for process and quality monitoring

The DC950H Fiber-Lite 150 watt Quartz halogen features DC regulated output, fast lamp response. It has a 0-5 VDC remote intensity control interface with linear voltage adjust-ment (8 bit D/A module available). This specification is very suitable for high speed processes and remote operational control. The source accepts a large range of configured fiber optics for structured lighting.

High intensity fibre optic light sources with remote lamp housings and independent power supplies

A241 and A242 Dual High intensity fiber optic illuminators have small size remote lamp housings driven by independent stabilised power supplies. The A242 has a dual combined housing with two 150 watt quartz halogen lamps and independent fiber optic connec-tions. The intensity for each lamp head is independently controlled via a potentiometer.


MH100 Metal halide illuminator for fiber optics

Delivers up to 2X the light output of standard quartz halogen light sources. The MH-100 is designed to provide brilliant white light with true colour rendering and balance. Features include 0-100% intensity control via manual iris, 5500K-6500K colour temperature.

Portable light sources for fibre optics and endoscopes

This series of quartz halogen and LED Illuminators are designed for remote inspection and measurement. Can be provided as a system with endoscopic cameras or miniature Spectrometers. Operates with a rechargeable portable power supply, and provides intensity.
