Digital butterfly laser controller CTL200 mechanical drawing CTL200 Graphical User Interface CTL200 current stability

Koheron CTL200 is the digital version of the popular CTL100 analog laser controller. It drives up to 200 / 400 / 600 mA laser current with a current noise density of only 230 / 450 / 670 pA / √Hz. 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.
