The PDL 828 “Sepia II” is a high-end, multichannel driver for the picosecond pulsed laser diode heads of the LDH Series and LDH-FA Series as well as for the sub-nanosecond pulsed LEDs of the PLS Series. Wavelength changes are simply performed by plugging in a different laser or LED head.

The Sepia II can either be controlled by the included software or by custom written software using the API. Demo Code utilising the API is available on GitHub.
