Sepia PDL 828

• Higher timing precision
• Improved long-term system stability
• Reduced setup complexity
• Reproducible measurement
• Easy system integration
• Scalable system growth

The PicoQuant Sepia PDL 828 is a modular multichannel picosecond diode laser driver designed for experiments requiring multiple excitation wavelengths and flexible timing control. It can operate up to eight laser or LED heads simultaneously or according to user-defined sequences.

The system combines a Sepia Oscillator Module (SOM) with individual Sepia Laser Driver Modules (SLM). This architecture enables programmable pulse patterns including simultaneous, sequential, delayed, and burst operation.

The Sepia PDL 828 is controlled via USB and dedicated Windows software, while stored settings allow the system to operate independently for automated measurement setups.
