Research QTH Lamp Source, 250 W QTH, F/1

The 66502-250Q-R1 QTH Light Source is a complete plug and play system that includes a 250 W lamp, a light source housing, a lamp power supply, as well as all the necessary interconnection cables for operation. See included components below for complete details.

The provided OPS-Q250 QTH lamp power supply is highly regulated for maximum stability. The lamp can be operated in current, power, or intensity control mode to meet the operational requirements of any use case.

The included Oriel Research QTH Housing offers a built-in ignitor board and rear reflector for optimum lamp performance. A built-in cooling fan maintains a safe operating temperature for the lamp. The user is protected from accidental exposure to UV radiation and electrical shock by the lamp housing's safety interlock, which disables ignition and power to the lamp if the housing door or lamp housing interconnection cable is not securely connected.

The condenser lens assembly included with this light source uses a fused silica asphere lens with an F/# of F/1. The front surface of an aspheric lens gradually changes in curvature from the center of the lens to the edge. This shape reduces spherical aberration more effectively than a Plano Convex Lens.
