IMM Photonics develops and produces fiber optic components including receptacles, multiplex modules and fiber collimators in Germany. Nearly all of these components are customer-specific. Their fiber optic components are used in electrical measurement, communication technology, medical engineering, and of course data transfer under harsh environments.

Pilot Laser Red/Green
IMM Photonics has developed a new duplex module as a pilot laser for high-power laser systems for the use in medical engineering or material processing.
Features: A stop filter was integrated for safe usage in high-performance lasers. It prevents reflections of the beam from affecting the laser diodes.
Advantages: Small dimensions, high mechanical stability, multiple adjustment possibilities, cost-efficient even with small volumes as a standard design.
A red (635 nm) and a green laser diode (520 nm) are coupled on a common fiber. The fiber end can either be bare or equipped with all readily available fiber optic connectors during production. Other fibers and fiber lengths are available upon request.
