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.

66502-250Q-R1 QTH光源是一个完整的即插即用系统，包括一个250w灯，一个光源外壳，一个灯电源，以及所有必要的互连电缆。详细信息请参阅下面包含的组件。

提供的os - q250 QTH灯电源高度调节，最大限度地稳定。灯可以在电流、功率或强度控制模式下运行，以满足任何用例的操作要求。

包括Oriel研究QTH外壳提供了一个内置的点火器板和后反射器，以获得最佳的灯具性能。内置冷却风扇保持灯的安全工作温度。保护使用者不受意外暴露于紫外线辐射和触电的灯具外壳的安全联锁，如果外壳门或灯具外壳的互连电缆连接不牢固，则该联锁将使灯具无法点火和供电。

该光源所包含的冷凝器透镜组件使用的是熔融石英沥青透镜，其F/#为F/1。非球面透镜的前表面从透镜中心到边缘的曲率逐渐变化。这种形状比平面凸透镜更有效地减少了球面像差。
