LED-based Calibration Standard

Gooch & Housego OrlandoRequest Info
 
Gooch & Housego's Calibration StandardsThe OL 458-4F white LED-based fixed luminance sphere calibration standard is the latest innovation from Gooch and Housego PLC’s Instrumentation division. The instrument was designed for accurately calibrating micro- and telephotometers, image intensifiers, and cameras. When calibrating imaging photometers and colorimeters, the OL 458-4F can be used for photometric, radiometric, and spectroradiometric response and more! It serves as a NIST-traceable highly accurate diffusely radiating source.

The OL 458-4F consists of an optics head and a power supply. This enables remote location of either unit, making alignment or positioning of the source with respect to the instrument a breeze. The ultra-compact package allows the unit to be used in confined spaces, making it an excellent check source for factories and assembly lines.

The temperature is held constant giving a large temperature range for operation without suffering from changes in the output. The optics head has dual input sources with multiple LEDs in each source. The LEDs excite a phosphor allowing for a continuous spectrum across the visible range. The LEDS and phosphor were chosen for their long lifetime and excellent photometric stability. The sources feed directly into a 4-inch integrating sphere coated with our proprietary Optolon2 material, providing highly diffuse reflectance over the VIS/NIR wavelength range. The Orlando Instrumentation division is also committed to providing custom wavelength ranges and packaging to fit your unique implementation.

GLOSSARY
luminance
Luminous flux emitted from a surface per unit solid angle per unit of area, projected onto a plane normal to the direction of propagation. Also known as brightness and luminous sterance.
radiance
Radiant power per unit source area per unit solid angle. Usually it is expressed in watts/m2/steradian.
