photoelectric photometer meaning
An instrument that uses a photoelectric device for the purpose of measuring the intensity of infrared radiation, visible light, or ultraviolet radiation.
"A photometer that uses a photocell, phototransistor, or phototube to measure the intensity of light. Also known as electronic photometer."
- In 1922 Carleton professor Edward Fath constructed one of the nation's first photoelectric photometers in Goodsell.
- The photoelectric photometer and the Boller and Chivens spectrograph have not been in use for more than a decade.
- For example, there was a photoelectric photometer fed by a 16 inch telescope with a six-position filter wheel.
- For data acquisition, students can use a research-grade SBIG STL-1001E CCD imaging system, a high-resolution SBIG spectrograph, and a photoelectric photometer.
- These have largely been replaced with CCD cameras that can simultaneously image multiple objects, although photoelectric photometers are still used in special situations, such as where fine time resolution is required.
