  • Infrared detectors | Hamamatsu Photonics

    The candela originally was derived from the light emitted by a candle; its current definition is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 10 12 Hz and that has a radiant intensity in that direction of 1/683 W per steradian (540 × 10 12 Hz is equivalent to 555 nm). The lumen is the luminous flux, emitted per unit solid angle from a point source whose …

  • Radiometry: A Simplified Description of Light

    A PMT is characterized by low internal noise, a gain (μ) on the order of 10 5 to 10 6 and an ability to detect single photons. A PD is a light-sensitive, solid-state device with a p-n junction and no internal gain (μ = 1). In a typical operation, a PD is reverse-biased to several volts.

  • Open Path Hydrocarbon Gas Detectors | GDS Corp

    Open path detectors consist of an infrared source that transmits a focused beam of infrared light across an area to be monitored into a detector located some distance away. Hydrocarbon gas passing between the transmitter and detector interferes with the infrared beam, and the detector uses this drop in energy to determine that gas is present.
