Halogen light sources (QTH)

Quartz Tungsten Halogen (QTH) light sources have high output power in the VIS and NIR range with only low UV content. Because of their stability, filament structure and high color temperature, our halogen light sources are suitable for many measurements and illumination applications. Compared to conventional filament lamps, our selected halogen lamps provide a "whiter" light with more intensity at the blue end of the UV-VIS spectrum.

Features
  • Two systems to operate halogen lamps rated from 50 - 400 W
  • Wavelength range: 250 - 2700 nm
  • Continuous spectrum
  • Superb temporal stability
  • Calibrated irradiance standards available

Further information

We offer  two systems: 50-150 W and 250-400 W. Both systems include already lamp housing, power supply, cables and adapters needed for a proper operation.
Simply select the right lamp and condenser optic for your application from a predefined number of matching items to complete the system.

With a large selection of optical and mechanical accessories the halogen light source can be adapted to your individual requirements.
