LS-65-8D

LS-65-8D: The latest advancement in our Luminance Standards Product line. Besides being easy to use, this microprocessor-controlled device is multi-detector monitored, allowing the highest accuracy available from a sphere-based standard. In addition, this instrument is an ideal NIST traceable platform for accurately calibrating photometers, radiometers, and other light measuring devices. It provides highly stable color temperature and luminance/radiance over the one-year calibration period. The silicon photodetectors are thermally stabilized to assure that high accuracies are maintained regardless of ambient environment.

Calibrated Lamps

Calibrated Lamps:  Hoffman Engineering manufactures a complete line of NIST traceable, precision standards for performing calibrations of visible/near-infrared devices. This series includes a variety of different lamps with precision-positioned filaments in a medium bi-post base. A variety of Radiance, Irradiance, Luminance, Illuminance and Color Temperature calibrations are available with traceability to NIST standards.

Spectral Reflectance Standard:  The SRS-2, ideal for conversion of illuminance to luminance or spectral irradiance to radiance, is a highly stable, neutral white reflectance standard. It has Lambertian properties over wide angles and can optionally provide bi-directional reflectance data over a spectral range of 300 to 900 nm.

Chromaticity Reference Filters:  The CF-35 MEL Chromaticity Reference Filter Set is a set of 20 - 2x2 inch acrylic filters used for providing the secondary Chromaticity and transmission standards needed in photometric and colorimetric laboratories.
