Halogen lamps
Halogen lamp also known as a tungsten halogen, quartz-halogen or quartz iodine lamp, is an incandescent lamp that has a small amount of a halogen such as iodine or bromine added. The combination of the halogen gas and the tungsten filament produces a halogen cycle chemical reaction which redeposits evaporated tungsten back onto the filament, increasing its life and maintaining the clarity of the envelope. Because of this, a halogen lamp can be operated at a higher temperature than a standard gas-filled lamp of similar power and operating life, producing light of a higher luminous efficacy and color temperature. The small size of halogen lamps permits their use in compact optical systems for projectors and illumination.
Iron mixed halogen lamp particularly enhanced 380nm as the highest peak, on photopolymer and daylight film exposure a very good effect.
Potassium mixed halogen lamp, particularly enhanced 403nm and 417nm wave crest, the highest peak for the Diazo material 417nm exposure the light is very obvious, and good effect.
