The LIK-LMP is a light intensity controller kit designed for use with OPS Series Power Supplies. The kit maintains a constant light output from DC arc and quartz tungsten halogen lamps when mounted to the proper housing and connected to an OPS Model Power Supply. The necessary cables and adapters for electrical and mechanical compatibility with the OPS Series Power Supply and Research or Q Series Lamp Housings are included with the LIK-LMP.

A TE cooled Si detector is used as the light sensing head. When used with the OPS-A Series Arc Lamp Power Supplies or OPS-Q Series Power Supplies this detector monitors light output from the DC Arc or QTH light source. Constant feedback of the light output allows the OPS Series Power Supply to determine how much voltage/current should be supplied to the light source in order to keep its output intensity constant as the light source ages. Using the cables supplied with the LIK-LMP for interface with the OPS Series Power Supply, the temperature of the Si detector is monitored and the current supplied to the TE cooler is controlled as well. This stabilizes the temperature of the Si detector, creating consistent detector feedback independent of ambient temperature variations.

The kit includes the following components:

• 71582 Si Detector Head, TE Cooled
• 70062 Thermoelectric Cooler Cable
• 70018 BNC-BNC Cable
• 68952 Adapter Kit to Research Arc Lamp Housings
• 68954 Adpater Kit to Q Series Lamp Housings
