Introduction
The PR-730 and PR-735 SpectraScan Spectroradiometers are advanced spectral measurement instruments designed by Photo Research, Inc. The PR-730 measures the visible spectrum from 380 to 780 nm, while the PR-735 extends to 1080 nm for near IR testing. These devices feature enhanced sensitivity, minimal polarization error, and reduced stray light. They include multiple apertures, double the detectors, and offer USB, RS232, and Bluetooth interfaces, along with a full-color touch screen and SD card storage.

Features
The PR-730 introduces variable spectral bandwidth with automatic selection among 2, 4, or 8 nm settings. The PR-735 offers 4, 8, or 14 nm options. These instruments provide flexibility with a wide range of optical accessories, allowing measurements of radiance, luminance, irradiance, illuminance, radiant flux, and radiant intensity. The Pritchard optics ensure 100% target alignment accuracy. The devices support wireless communication via Bluetooth and can store extensive measurement data on an SD card. They also feature AutoSync for accurate results regardless of device refresh rates and offer an optional Li-ion battery for field use.

Applications
The PR-730/735 is suitable for various industries, including aerospace, displays/HDTVs, components, and automotive. It addresses challenges such as low to high photometric levels and spectral contrast measurements. The instruments are compatible with a range of accessories, including the LR-127 LED Analyzer and integrating spheres.

Software
SpectraWin® software provides a Windows-based interface for measurements, graphical data display, and data manipulation. It supports XP, Vista, and Windows 7. Additional modules include an RGB Display Cal Module for display calibration and User Self Calibration Software for in-house calibration.

Measurement Capabilities
The PR-730/735 measures luminance, chromaticity, correlated color temperature, dominant wavelength, and spectral power distribution. It includes a CIE Pass/Fail mode and features an on-board CRI measurement mode for evaluating color rendering capabilities.

Specifications
The PR-730 operates within a wavelength range of 380-780 nm, while the PR-735 extends to 1080 nm. Both models feature 512 cooled detectors, with spectral bandwidth options and wavelength accuracy of <0.4 nm for the PR-730 and <0.8 nm for the PR-735. They offer digital resolution of 16 bits and multiple measuring apertures. The instruments are equipped with USB, Bluetooth, and RS232 interfaces, and can be powered by a rechargeable Li-ion battery or AC adapter.
