Reliable and Repeatable High Voltage in Photonics (Part 3 of 3: Detectors)

High Voltage

In part one and part two of our three-part series, we discussed laser photonics and electro-optics. This final part of our series cover detectors. Optoelectronic detectors are used for measuring photon, electron, and ion energy from various sources such as ion beams, electron beams, x-rays, lasers, phosphors, dyes, LEDs, and lamps. Common types of detectors include photo-multiplier tubes (PMT), avalanche photo diodes (APD), micro-channel plates (MCP), silicon detectors (SID), PIN diodes, charge-coupled devices (CCD), and thin-film transistors (TFT).

Detectors vary in spectral response, quantum efficiency, bandwidth, signal-to-noise ratio, and configuration (large area, matrix). Common to many detector requirements is the need for a controlled voltage that is adjustable for initial calibration, detector aging, or temperature fluctuations. Other performance requirements are current limiting; low ripple (< 0.01%) to very low ripple (< 5 ppm); and tight stability over time, temperature, and load. Depending on application, the detector may use a second high voltage to bias a scintillator material.

Advanced Energy offers the VM, and D series of DC-to-HVDC for miniature applications such as hand-held or battery-powered devices. These are the smallest, full-feature devices in the industry for their voltage and power class. Advanced Energy also offers the AA-F (with filter), AAPPM, and PM10 series DC-to-HVDC supplies to support higher-powered 4 W to 30 W applications.

The Advanced Energy high-voltage product line delivers excellent performance and enabling key features, and the products are supported by experienced technical sales and applications engineering support staff worldwide.
