Selenium diodes are another example of an early discovery followed by a delayed practical use. The first selenium diode was constructed in 1886 by ... bias should work quite well as detector diodes.

Avalanche photodiodes are widely used as practical detectors of single photons1. ... Pellegrini, S. et al. Design and performance of an InGaAs-InP single-photon avalanche diode detector.

The corresponding detection sensitivity of 75,400 mV mW −1 is substantially larger than state-of-the-art biased Schottky diode detectors (3,800 mV mW −1, Herotek, Inc.) and the best existing ...

Heated Diode Detectors. With a heated diode detector, sampled air is heated to a high temperature, ionizing halogenated refrigerant gases. The resulting charged chlorine and fluorine ions, even in ...

Ultra Violet/ Visible absorbance (UV/Vis), Fluorescence (FL), Refractive Index (RI) and Photo Diode Array absorbance (PDA or DAD) detectors are covered in detail. Delegates will learn the operation ...

4 quadrant NIR photo diode leaks only 5nA ElFys has launched circular four-quadrant near-infra-red detector with a 14mm diameter active area, leading to 38.5mm2 of sensing surface in each quarter.
