Mini Light Sources

We offer two mini light sources ideally suited for transmittance and reflectance measurements with the IS and OSM Series of minispectrometers. The LSM-DT-S is a deuterium and tungsten-halogen dual source. You can run the lamps separately or simultaneously for very broadband output. The LSM-T-S is a tungsten-halogen source. Both sources have an integrated shutter for dark measurements. An SMA termination accepts any SMA terminated fiber; we recommend using a 200 to 600 µm core fiber. Please order fiber separately.
