Spectral Radiance / Luminance Standards
A recognized worldwide leader in high quality spectroradiometric, radiometric, and photometric standards, we offer one of the most complete selections of calibration standard in the industry. Since 1970, we have been in the forefront of developing and supplying NIST-traceable standards, enabling our users to approach state- of-the-art accuracies when calibrating optical radiation measurement instrumentation.
The OL 480 serves as an accurate, variable temperature (100 to 1200°C) blackbody calibration standard. It is extremely useful for calibrating infrared radiometric and spectroradiometeric measurement systems. The OL 480 has an emissivity of 0.99 ± 0.01 and an uncertainty in the digital temperature readout of ± 2°C.
The OL 458-4 is a NIST-traceable, white LED-based integrating sphere calibration standard, designed for accurately calibrating micro- and telephotometers, image intensifiers, and imaging photometers. A proprietary design allows for true continuous spectrum across the visible range. Precision source temperature control delivers extremely stable output over long periods of usage. The design and output are customizable upon request.
The OL Series 455-SA Automated Integrating Sphere Calibration Standard is designed for accurately calibrating microphotometers, image intensifiers, telephotometers, and imaging spectroradiometers for photometric, radiometric, and spectroradiometric response. It is a large area, uniform, diffusely radiating source with a near normal luminance that can be varied over many decades without changing the color temperature.
The OL Series 455-S Integrating Sphere Calibration Standard is designed for accurately calibrating microphotometers, image intensifiers, telephotometers, and imaging spectroradiometers for photometric, radiometric, and spectroradiometric response. It is a large area, uniform, diffusely radiating source with a near normal luminance that can be varied over many decades without changing the color temperature
The OL 440-8-OH Variable Ultraviolet Integrating Sphere Calibration Standard is designed for accurate calibration of UV microphometers, image intensifiers, telephotometers, and imaging spectroradiometers for measuring spectral radiance. It consists of a source module/ optics head and a separate electronic display console and power supply (OL 46D Controller). This enables remote location of either unit, which facilitates alignment or positioning of the source with respect to the device to be calibrated.
The OL Series 426-S Integrating Sphere Calibration Standard is designed for accurately calibrating very sensitive microphotometers, image intensifiers, telephotometers, and imaging spectroradiometers for photometric or spectroradiometric response at moderate to extremely low light levels. It serves as a highly accurate, large area, uniform, diffusely radiating source with a near normal luminance that can be varied over nearly six decades with essentially constant color temperature. The OL Series 426-S consists of an OL Series 426-S Optics Head and an OL 400-CS Controller.
