Since July 2005 all T- and Q-series Broadlighters are delivered with RS-232 remote control capability. Superlum offers companion software to operate your T- or Q-Series Broadlighter remotely from your PC/laptop. Please see the downloads page for details.

Superlum T- and Q-series Broadlighters are broadband, very low coherence wall-plug light sources based on three (T-series) and four (Q-series) fiber coupled superluminescent diode modules with slightly shifted central wavelengths, which are combined by appropriate broadband singlemode fiber couplers for the best combination of output power and spectrum width. Design of SLD module controllers ensures excellent operation stability of light sources.

The devices are developed for optical test and measurement applications including:

• Optical coherence tomography.
• Characterization of optical components.
• Optical fiber metrology.
• Optical measurements.

The following T- and Q-series Broadlighters are commercially available:

• T840, 100 nm light source at 840 nm with output power 15 mW (about 7 µm coherence length).

• T870, 180 nm light source at 870 nm with output power 8 mW (coherence length well below 5 µm!).

• Q870, combines the spectra of four SLD modules. 200 nm FWHM bandwidth with output power 5 mW.

• Q940, a mean wavelength of 940 nm. 300 nm FWHM bandwidth with output power 4 mW.

• Q1350, a mean wavelength of 1370 nm. 200 nm FWHM bandwidth with output power 5 mW.

• Q1430, a mean wavelength of 1430 nm. Up to 250 nm FWHM bandwidth with output power 5 mW.
