The Bentham collimator has been designed for use with monochromators and light sources in dituations where a monochromatic and parallet beam of light is required. Applications include transmission measurement through aerosols and detector calibration.

In the former, the collimator is attached to a white light source with a simple condensign arrangement attached to the entrance slit of the monochromator which may be some distance away.

For detector calibration, the COL1 is fitted with an adjustable iris which allows the operator to set beam diameter between 2 and 20mm.

The COL1 uses a 2-lens systems with interchangeable apertures to allow the user to optimise the throughput/power trade-off.

The first lens produces an image of the source with unity magnification at the plane of the interchangeable aperture. The second lens is positioned at its focal length of 150mm from the aperture.
