The standard objective lens for the PR-7XX is the MS-75 - a 75mm f/2.8 MacroSpectar
®
lens that focuses from
1:4 magnification
(at 14” from the target) to infinity. This objective lens enables the PR-7XX to perform a variety
of measurements including luminance, radiance, spectral radiance, chromaticity, correlated color temperature
(CCT), Color Rendering Index (CRI), dominant wavelength, etc.
For applications other than radiance or
luminance the PR-7XX can be supplied with optical accessories such as a cosine receptor for irradiance /
illuminance, LR-730 LED Analyzer for testing LED's for CIE 127 conformity, fiber probe for remote non-line-of-
sight luminance testing, and a series of magnification lenses for small spot size analysis. Refer to the Optional
Accessory section for more information on all available optical accessories.
