Heraeus has designed a series of tungsten halogen lamps (TH) specifically for use in analytical applications. Special quartz envelopes enable high transmission below 380 nm and the position of the tungsten filament is closely controlled through precise alignment.
The production of tungsten and tungsten-halogen lamps will be discontinued at Heraeus Noblelight in September 2022. The products will continue to be available and can be purchased in future from Speziallampenfabrik Dr. Fischer GmbH . Manufacture and distribution of these products has been transferred to Dr. Fischer.
The lamps offer high colour temperature, luminous efficacy and long life. TH lamps are filled with a halogen gas mixture specific to their final application and range from 5 W – 200 W, with typical lifetimes of more than 2,000 hours. Lamps can be designed and built according to OEMs specific requirements, such as colour temperature, voltage, wattage and mechanical tolerances. Each lamp fit for purpose, ready finished to drop into the instrument. No pre-selection required.
