D-series Broadlighters

Superlum D-series Broadlighters are very broadband, low-coherence AC powered benchtop light sources based on two single-mode fiber coupled superluminescent diode modules with slightly shifted central wavelengths combined by an appropriate broadband single-mode fiber coupler. The design of SLD module controllers ensures excellent operation stability of light sources. The most powerful versions are available with and without optical isolators that protect SLDs from optical feedback.

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 D-series Broadlighters are commercially available (since April 2011, model D-840-HP has replaced D-830 and D-855):
