Irradiance standard 250 - 4 500 nm | OL 200, 220, 245 series

We offer 1000-W (OL Series 200), 200-W (OL Series 220), and 45-W (OL Series 245) tungsten-halogen lamps, which are calibrated over all or part of the 250 to 2500 nm wavelength range. The 1000-W and 200-W versions are offered with high accuracy and super high accuracy options. The high accuracy standards have a transfer uncertainty relative to the NIST Scale of ± 1 - 2%, and the super high accuracy standards have a transfer uncertainty of ± 0.5%. Additionally, the wavelength ranges of the 1000-W and 200-W lamps can be extended out to 4500 nm. Illuminance, color temperature and chromaticity values are also supplied with those standards calibrated over the visible spectrum.
