LS 100 / LS 500 - Light sources from the UV to the IR

The light sources of the LS 100 und LS 500 series were developed by Instrument Systems specifically for use with optical fibers. These light sources ensure efficient coupling even into multimode fibers. Assorted versions cover the spectral range from the UV to the IR.


SMA connectors and fiber bundle adapters are available for all models, providing compatibility with our measurement accessories and the appropriate type of optical fiber. Stabilized power supplies are available for models from the LS 100 series. For models from the LS 500 series, the power supply is integrated into the housing.

ModelSpectral range Features
LS100-130350 - 2200 nm  100 W halogen lamp with broad band reflector; high stability for T/R measurements
LS500-110 190 - 2500 nm Combined light source with 20 W halogen and 26 W deuterium lamps

Model LS500-110 is equipped with both a halogen lamp and a special deuterium lamp for the low UV range, enabling a broader spectral range of 190-2500 nm. The model has a shutter to limit the illumination of samples with UV radiation. In addition, the deuterium and halogen lamp can be individually switched on and off remotely.
