fO-6000 High color temperature tungsten light source LED-Lite™ Modular LED Light source with exchangeable LEDs The LED-lite is a power supply for WPI’s ELS LED modules for monochromatic light excitation. Each ELS module has an SMA bulk head fitting and allows direct attachment of SMA terminated fibers. ELS module This new miniature tungsten FO-6000 Spectrum light source has been developed for high precision 1. 0 portable and low-power 0. 8 spectroscopy applications. 0. 6 Its advantage lies in its high light power output, its 0. 4 effective color temperature 0. 2 FO-6000 of 6000K and its 2760 K Tungsten Lamp 0. 0 exceptionally low drift below 300 400 500 600 700 800 900 1000 0.5 mAU/h. The FO-6000 Wavelength [nm] is a light source for the extended visible part of the light spectrum (380 nm – 1700 nm). It has a SMA type output connector. Shutter and lamp can be operated via TTL external triggering. This light source offers a wide assortment of field applications in analytical chemistry as well as environmental and life science. A significant problem with tungsten light bulbs is their inherent low light output at wavelengths below 430 nm. The FO-6000 was developed to overcome this limitation. The light intensity of a tungsten light bulb (2760K) drops below 10% at 420 nm wavelength. However, using FO-6000, the light intensity drops below 10% at 370 nm, where the intensity of the conventional tungsten light bulb is at approximately 2% relative light output. The inherent low noise and low drift of the FO-6000 makes it particularly suitable for low-noise detection systems.

This allows a virtual light loss free insertion of optical filters with outer diameters from 8 to 25.4 mm and thickness ranging from 2 to 10 mm into the light path of the FO-6000. With this filter holder and an optical filter, a highly stable monochromatic light source can be assembled.
