About This Product

■Summary

This is a standard light source with a wavelength range of 250-2,500nm. It serves as a reference for spectral irradiance, spectral radiance, illuminance, brightness, and color temperature. You can choose from two calibration wavelength ranges. A standard light source mainly used for calibrating measuring instruments. The OL345 standard light source consists of a 45-watt halogen tungsten lamp and a removable 2-inch diameter flash opal diffuser mounted in an air-cooled machined cylindrical housing. With the diffuser installed, the 15.5 cm2 uniform radiation source is used as a reference for spectral radiance and brightness in the wavelength range of 350 to 1,100 nm. With the diffuser removed, the OL345 becomes a standard for spectral irradiance and illuminance from 250 to 2,500 nm. Additionally, the OL345 can operate at a predetermined color temperature of the light source. Equipped with a filter holder that allows you to insert a 2 inch square filter between the light source and the diffuser. Spectral shaping filters are available to simulate various CRT phosphor screens and obtain color temperatures up to 6,000K. Narrowband interference filters are also available to obtain individual spectral irradiances.
