OL 440-8-OH Variable Ultraviolet Integrating Sphere Calibration Standard

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.
