The Integrating Sphere Calibration Standards are the preferred highly accurate self contained Luminance, Color Temperature, and Radiance Optical Radiation Standard. Photo Research offers a full range of configurations having outputs from low levels of 1 x 10 4 fL to 15,500 fL, Color Temperatures of 1800 Kelvins to 3000 K (unfiltered) and up to 7500 K of filtered Standards.
Integrating Sphere Calibration Standards
Integrating Sphere Calibration Standards These sources can be utilized for accurate calibration of image intensifiers, microphotometers, telephotometers, video photometers, radiometers, and spectroradiometers. We also offer a series of fully automated microprocessor controlled integrating sphere sources to enable the automation of calibrations for efficiency and repeatability. These sources offer access to all functions via a standard configuration RS-232 or an optional IEEE-488 interface.
The Wavelength Calibrators are utilized for the wavelength calibration of spectroradiometers, spectrophotometers or monochromators. Their well known emission characteristics serve as an intrinsic calibration standard to analyze and calibrate a system's spectral dispersion. These sources do not require periodic calibration.
Reference Light Sources
The 2300 Series of Reference Light Sources provide an economical and convenient means of verifying calibration of photometers and spectroradiometers. While they are not absolute standards that is, they do not provide a perfect lambertian distribution at a specific color temperature the sources do provide a calibrated reference, which is constant to within 2%. They are available in three fixed output models, providing 9fL (30 cd/m²), 100fL (350 cd/m²) or spectroradiometrically calibrated output. A fourth version at approximately 4700 Kelvins is available for spectrophotometric applications.
