Semiconductor Laser by Philip Harris

A compact fully solid state instrument which produces an intense beam of light at a wavelength of 630nm and can be mounted directly upon a standard type optical bench. An adjustable collimator is incorporated providing focusing facilities and control over beam divergence. A useful feature is the modulation facility which permits experiments in laser communications and speed of light investigations to be carried out. Modulation may be demonstrated by means of the built-in oscillator, or from an external signal source. For these applications a Modulated Receiver Unit is available (B8A46176). The case has rubber feet to aid stability.

A key operated ON/OFF switch is incorporated for safety. (Please contact techsupport@philipharris.co.uk if a spare key is required).
