Caspian C-39N0-160




The Caspian C-39N0-160 is an electronically focus controllable C-Mount objective, based on the Arctic 39N0 Liquid Lens. It incorporates all necessary electronic components to drive the Liquid Lens, and just needs a DC power supply; focus can be controlled through either an RS232, I²C, Analog or SPI input. With a 16 mm EFL, and compatible with 2/3" sensors, it is specifically designed for machine vision applications.
