Koheron CTL200 is the digital version of the popular CTL101 analog laser controller. It combines a low noise current driver with modulation and a temperature controller. The CTL200 fits in a 75 mm x 75 mm square, uses a single 5.9 V supply, and can operate between 0 and 50°C. The CTL200 is conduction-cooled. It comes with an aluminum base plate and a zero insertion force socket for easy mounting. The CTL200 is also available in a screw terminal version.
