PR-730 uses 512 detectors to sample the emitted spectrum from 380 to 780 nm yielding a resolution of 0.781 nm/pixel. Data is reported every 1 nm. The spectral range of the PR-735 is 380 to 1080 nm for a resolution of 1.348 nm/pixel and reported in 2nm increments. Ease of navigation through menus, and vivid information screens including a full color spectrum, is supplied by the high resolution color touch screen display. Up to 8 measuring apertures can be supplied on the instrument providing unequaled spot size /sensitivity flexibility. The capability to synchronize measurements (AutoSync®) to the frequency of the source (e.g. 70Hz display) means repeatable results. An external trigger circuit lets you make precise measurements of flashing sources such as xenon strobes. The PR-730 can measure as low as 0.0001 (0.00005 for the PR-735) footlamberts (0.0003 or 0.00015 cd/m²). Accurate measurements of polarized sources like LCD's is guaranteed by the extremely low polarization characteristcs (<0.2%).
