LSS Light Sequence Switch

Precise control of lighting for Computational Imaging

The LSS-2404 Light Sequencing Switch is designed to be the heart of any computational imaging system and can switch external +24 VDC power for up to 4-channels of lights. Upon receiving an external system trigger, the LSS-2404 executes a pre-programmed sequence of lighting on the 4-channels and outputs a correlated camera trigger, automatically timing an external camera exposure to the programmed lighting sequence. May be set-up as master or slave in a system.
