Tungsten-halogen lamphouse
Description
These tungsten-halogen lamphouses, available in two sizes, have efficient aspheric condensers to collimate the output, and optional back reflectors to further improve light collection. Heat is dissipated efficiently by the vertical chimney design and ceramic lampholders with high-temperature flying leads are provided. Lamps should be ordered separately from our lamp section.
The lens tube has a standard TubeMount thread (25mm for small, 50mm for large lamphouse) to which condenser lenses to project a filament image can be attached. Any other lens, filter etc. mounted on an ML mount (see spigoted lens cells and our mounting options) can also be screwed in.
Lamphouses are available as basic bodies or with mounting posts for use on optical tables etc. The ventilation holes at top and bottom must not be obstructed.
Special optics, such as fused silica for UV, can readily be provided.
Over- and under-running
Long-life lamps have lower luminance and efficiency than short-life types. The balance can be adjusted by running lamps at higher or lower than the rated voltage. The effect of this should be verified by trials but can be estimated by the following useful rules of thumb.
Life ∝ V-12
Wattage ∝ V1.5
Output ∝ V3.5
