Photoelectric Photometry

OAC's staff has a long time experience in stellar photoelectric photometry.
Photoelectric photometry is an important tool in order to get high precision photometry, which is needed in various fields of astronomy and astrophysics.
Photoelectric photometry is performed by means of a device named photoelectric photometer.
At OAC we use three different photoelectric photometers:

  • IRF's optical photoelectric photometer Optec SSP-5A (with Hamamatsu R6358 low noise red-extended photomultiplier tube); it is a direct current photoelectric photometer with voltage to frequency converter

  • OAC's optical photoelectric photometer Optec SSP-5A (with Hamamatsu R6358 low noise red-extended photomultiplier tube)); it is a direct current photoelectric photometer with voltage to frequency converter

  • OAC's near-infrared photoelectric photometer Optec SSP-4 (with Hamamatsu G5851-21 InGaAs-PIN photodiode)

For details and info about OAC's photometers and the photometric filters used, please see the link "Opto-electronic Instrumentation".
