Product description
BLM2-D-series Miniature Broadband Light Source Modules with Extended Bandwidth are powerful and very broadband light sources
based on a combination of two SLDs with slightly different center wavelengths. A built-in, stable and reliable digital dual-channel
SLD current and temperature controller allows the switching of SLDs on and off either by a pushbutton, or externally by TTL,
or from a PC via an RS-232 port. BLM2-D sources ensure quick and simple installation on the modular level and stable and reliable operation.
Features
- Very wide emission spectra
- High optical power
- Miniature design (dimensions of 100 × 120 × 31 mm)
- +5 V DC supply
- RS-232 and TTL control
- Excellent stability
- Low noise
Optical characteristics of standard models
Main optical parameters of standard BLM2-D light source modules are presented in the table below.
Standard models produce broadband emission in 780 – 920 nm spectral band, however the flexible design of
the light source and a great number of different SLD modules available for integration allow a lot of customized light sources to be designed.
The optical spectrum and the coherence function can be viewed as a web page (HTML) or downloaded in PDF format.
 – bell-shaped spectrum,  – multi-humped spectrum.
