Universal chimney-style lamp housing, McPherson Model 621

Universal Chimney-style Lamp Housing

The Model 621 modular light source operates with a variety of light sources: tungsten, Xenon and IR emitters. It is a complete system with forced air cooling, lamp mount module, housing, condenser, power supply and cables. The Model 621 mounts directly on the 5-inch diameter entrance slit of any McPherson spectrometer and may be adapted to other spectrometers or for standalone operation.
Easy access to the housing interior and simplifies lamp and socket exchange. Adjusters for focus and alignment are externally accessible. Safety interlocks prevent shock hazard while power is applied. Forced air cooling, compartment reflectors and airflow baffling insures even heat removal from the system. This optimizes the sources stability and longevity.
