The Model 190-1 is a 30 Watt, quarts halogen illumination system capable of delivering over 10,000 foot candles of intense, cold illumination. The light source features a rugged, convention cooled enclosure which results in zero noise, vibration, or air particle generation, important benefits in semiconductor and other microscopy applications. The 4 position, solid state, light intensity switch allows the selection of appropriate light levels and significantly increases lamp life at lower settings. The system includes the BGT1826 Optic light guide and LH759 Focusing Lens. Its rugged enclosure with hard mounting capability makes the Model 190-1 ideal for industrial applications.
