CrystaLatch™ 1×5, 1×6 PM High Power Reflection Optical Switch

Enquire Now

The CL 1×5 or 1×6 Series reflection switch connects optical channels by redirecting an incoming optical signal into a selected output fiber at the same time collect the reflected signal into a dedicate sensor port. This proprietary configuration is designed for sensor and LIDAR application, minimizing optical loss and eliminating the need for additional circulator or coupler.  The switching is achieved using patented non-mechanical configurations and activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed.

This series of reflective switches are designed to meet the most demands of continuous operation without wear-out, longevity without fail, and live operation under vibration/shock, as well as -40 0C operation. Electronic driver is available for this series of switches.
