BLMS mini SLD Light Sources

BLMS mini

Product description

BLMS mini is an SLD light source which combines a fiber pigtailed SLD module, a high precision current and temperature controller, and an optional optical isolator in one compact and easy-to-use device. Each product is custom made with the SLD module of your choice (please refer to the SLD product page to select an SLD module for your application).

The light source has an I/O interface for remote control and monitoring (a DB-25M connector for the Standard-I/O Version of BLMS mini, and a USB Mini-AB connector for the Alternate-I/O Version of BLMS mini). The Standard-I/O Version, designed for integration with customers' systems, provides a simple interface based on TTL level input/output and analog output signals via a DB-25M connector. The Alternate-I/O Version is equipped with a USB interface (Mini-AB connector) and can be operated remotely from a PC or laptop.
