Tungsten halogen lamp light source Gloria-T150A

■ Stable VIS-NIR sources ■ Precision external lamp adjustments ■ Choice of different UV-NIR condensing optics for collimated beam ■Supports wide range of accessories The collimated bean diameter is 46mm and optical axis height is from 157 to 193mm. Cooling Tungsten halogen Lamps become up to 900℃ hot (surface temperature)during operation,They require a safe, temperature-controlled environment. Below 200℃ the halogen cycle does not work any more. There is also a maximum permitted pinch temperature which must not in any case be exceeded during opera- tion. The housing has a cooling fan built in that provides the proper air flow. Reflector A spherical reflector collects the output from the rear of the lamp and focuses it on or near the arc, forcollection by the condenser.The output is increased by as much as 60 %. Lamp adjustment The housing has precise external lamp adjusters. They let you place the filament where it is needed. This is important for simplifying fiber and slit illumination. In many applications this eliminates the need for readju- sting any optics located in the beam path outside the housing
