The APD12703 series photodetector uses a 3mm diameter large target APD photodetector with very high gain and UV enhancement at 355nm, very suitable for fluorescence detection and other scenarios.
The DET30 bias photodetector is a compact, unamplified, fiber-optic input, battery-powered detector with very low noise, and can be used to detect optical signals with ps-level pulse widths.
PN12 high precision regulated linear power supply ±12VDC, voltage ripple Vpp 5mV, suitable for powering photodetectors and other precision instruments.
