66902 In Stock

The 66902 by Newport is a Arc Lamp Housing, a specialized aluminum enclosure designed to accommodate various lamp types while offering essential components such as an ignitor, condensing optics, a rear reflector, and a lamp cooling fan. This housing is specifically tailored to support 50 to 500 Watt Hg(Xe) DC, Xe, and Hg arc lamps, making it versatile for a range of applications. To ensure precise optical performance, the 66902 utilizes a F/1 two element fused silica condenser, delivering a collimated beam with a diameter of 1.3 inches at the 1.5-inch series output flange. The housing belongs to a family of compatible housings, allowing users to easily interchange between lamp wattages and types by changing the socket adapter.

The 66902 stands out with its large diameter collimated output and employs asphere condensers to achieve superior uniformity in light distribution. It incorporates a socket adapter that securely positions the lamp at the correct optical height for optimal performance of the aspheric condenser and rear reflector. Rear reflectors collect back radiation from the lamp, increasing the overall output by approximately 60%. Additionally, lamp adjusters are offered to fine-tune the lamp's positioning and compensate for any variations between lamps, ensuring consistent and reliable results. To prevent accidental exposure and damage, the 66902 features a door interlock mechanism that automatically halts lamp operation when the door is open. Furthermore, a built-in temperature sensor is employed to monitor the lamp's operating temperature. Based on this data, the cooling fan is controlled to maintain the lamp at an optimal temperature.
