BeST-SLED® Superluminescent Diode Light Source 2018-02-13T22:23:08+00:00


Optical Package

The BeST-SLED® is a rugged, compact broadband light source in the near infrared wavelength range. It offers spectral coverage from 1230nm to 1730nm with up to 50mW of optical power. The BeST-SLED® is comprised of a set of superluminescent diodes and driver circuit.

The BeST-SLED® incorporates a set of superluminescent diodes with overlapping spectral coverage into a 32 pin butterfly package. This module can be sold separately, and directly integrated into existing OEM products.

The BeST-SLED® driver circuit provides clean, stable power, an external trigger, manual switches for individual SLED control, a status display, a system on/off switch, control software, and I/O via USB or Ethernet.
