OL Series 200, 220, 245 High Accuracy Standards of Spectral Irradiance
These standards from Gooch & Housego consist of 1000W, 200W and 45W Tungsten-halogen lamps which are calibrated over all or part of the 250nm to 2500nm wavelength range. The 1000W and 200W versions can be obtained with two levels of accuracy: high accuracy and super high accuracy. The High Accuracy Standards of Spectral Irradiance have a transfer uncertainty relative to the NIST Scale of +/-1-2%. The Super High Accuracy Standards have a transfer uncertainty relative to the NIST scale of +/-0.5%.

OL-FEL High Accuracy Irradiance Standard
The OL-FEL standard from G&H is a 1000W FEL type lamp which is calibrated over all or part of the 250nm to 4500nm wavelength range. The lamp bases have been converted to a medium bi-post base as recommended by the National Institute of Standards and Technology (NIST). This special lamp base improves alignment accuracy which minimises uncertainties due to positoining and orientation of the lamp. The OL-FEL can be obtained with two levels of accuracy: high accuracy and super high accuracy. ed with those standards calibrated over the visible spectrum.

OL Series 100 Solar Constant Irradiance Standard
The OL100 from G&H consists of a 1000W tungsten-halogen lamp mounted in a slip-case, fused silica reflector. The diffuse reflector increases the irradiance by a factor of about three. The standard can be obtained with calibrations for spectral irradiance over the wavelength range of 200nm to 2500nm and for total irradiance. The total irradiance of the OL100 is on the order of 136mW/cm2.

OL Series UV-40 Ultraviolet Irradiance Standard
The OL UV-40 from G&H consists of a stable, 40W deuterium lamp with a fused silica window. The UV standard has a peak irradiance around 200nm and is calibrated over the range of 200nm to 400nm.

OL-Series 752-10 Plug-In Standards of Spectral Irradiance
The OL Series 752-10 from G&H consists of a pre-aligned, tungsten-halogen lamp calibrated for spectral irradiance over all or part of the 250nm to 2500nm wavelength region. The standard mounts directly to the integrating sphere cosine collector of the OL Series 754 and OL Series 750 Spectroradiometers. The plug-in/pre-aligned concept eliminates tedious and time consuming set-up and alignment procedures that are normally associated with spectroradiometric calibrations.

OL Series 752-12 Plug-In Ultraviolet Irradiance Standard
The OL752-12 from G&H consists of a prealigned, deuterium lamp standard calibrated for spectral irradiance over 200nm to 400nm wavelength region. The standard mounts directly to the integrating sphere consine collector of the OL Series 754 and OL Series 750 Spectroradiometers.

OL345 Radiometric and Photometric Calibration Standard
The OL345 Calibration Standard from G&H consists of a 45W tungesten-halogen lamp and a removable flashed opal diffuser mounted in an air-cooled cylindrical housing. With the diffuser in place, the uniformly radiating 15.5cm2 source serves as standard of spectral radiance over the wavlength range of 350nm to 1100nm and as a standard of luminance. When the diffuser is removed, the OL345 serves as a standard of spectral irradiance over the 250nm to 2500nm wavelength redion and as a standard of illuminance.
