ASB-W-030高稳定卤钨灯光源

The 30 Watt tungsten-halogen lamp used in the ASB-W-030 has a nominal color temperature of 3100 K and an average life of 400 hours at this temperature. The color temperature of the lamp is directly proportional to the lamp current which may be varied ± 25% with a control knob on the power supply. Over this range, both illumination and average life will change by approximately ± 50%. The optics of the ASB-W-030, in combination with the 30 Watt lamp, provide maximum illumination for monochromators. Higher power lamps have larger filaments, but no greater brightness per unit area. A filament larger than the 30 Watt size would simply overfill the entrance slit. The power supply provided with the ASB-W-030 is a DC current regulated power supply. Current regulation optimizes color temperature stability.
