The KI-125 Koehler Illuminator is designed for applications requiring uniform illuminance in the UV-VIS-NIR region of the spectrum. The Koehler Illuminator is a halogen lamp mounted in a lamp housing combined with a focusing optics assembly. The image of the halogen lamp filament is focused on a glass rod that evenly mixes the light distribution and directs the radiance through a fixed aperture before it passes through a baffled lens assembly and an adjustable iris diaphragm. The iris diaphragm controls the amount of illumination at the working plane. The KI-125 Koehler Illuminator features a 125 watt tungsten halogen lamp with a mounting boss attached to a 1/4-20 rod that slides into the sleeve of a sturdy 6 in. x 6 in. support base, allowing for height adjustment or alternate mounting. The KI-125 provides a maximum illuminance output of 20,000 lux at a normal working distance of 50 cm. Included is a 6 foot cable with a 2-pin male connector to operate with a power supply. A filter holder allows the placement of 1 inch diameter color balancing filters, narrow band filters or neutral density filters between the lamp and the glass rod. A lens cover protects the Koehler Illuminator when not in use.
