The PR-705/715 is the next generation of sophisticated, lab grade, fast scanning spectroradiometers. It is a stand-alone instrument that maintains the exceptional performance that has made the SpectraScan series the industry standard for accurate spectroradiometry in the industries such as Automotive, Aerospace, Computer, Lighting and Display Manufacturing. The PR-705/715 is designed to quickly measure (in as little as 50 milliseconds) the intensity and colour of light sources, displays and reflective or transmissive samples with NIST-traceable accuracy. It is he perfect instrument for manufacturers to establish measurement correlation with their vendors and customers to ensure that products meet the tight photometry and colourimetry specifications. One of the key features that makes the PR-705/715 an essential tool for both R&D and QC/QA testing is it's ability to precisely measure areas as small as 0.02 mm with the highest accuracy and repeatability. Stand-Alone Optical Head Spectral measurements are made in near real-time as light passes through a measuring aperture, is dispersed by a diffraction grating and then imaged onto a multi-element detector. The Automatic Adaptive Sensitivity feature optimises the dynamic range and increases Signal-To-Noise by selecting exposure times based on the available signal level. World famous Pritchard™ optics permit precise viewing of the target while allowing only the measured optical radiation to pass through to the detector. The incoming light is dispersed by a holographic diffraction grating and the dispersed spectrum is measured by a thermo-electrically cooled silicon diode array detector. The PR-705 measures Spectral Power Distributions in the visible range from 380-780 nm and the PR-715 measures the visible/NIR range from 380-1068nm. Optics are designed to minimize polarisation error resulting in accurate measurements of polarised sources such as LCDs. Since the cooled detector is housed in a hermetically sealed, pressurised chamber, the PR-705/715 makes extremely stable and repeatable measurements. State-of-the-Art Optical Design One of the primary benefits of this versatile instrument is its portability as it can be used stand-alone. This allows users to make outdoor measurements and test instrument panels inside cockpits and automobiles. Two powerful on-board microprocessors control the hardware and mathematically calculate photometric and colourimetric values for the acquired spectral data during a measurement. As a result, there are no errors in colour accuracy due to filter mismatches from the CIE specified functions as in the case of filter colourimeters. The PR-705/715 provides accurate answers for the luminance and colour regardless of the source distribution. Greater flexibility and enhanced sensitivity The PR-705/715 can accommodate one to six measuring fields (2°, 1° , 1/2° , 1/4° , 1/8° and special slits). If multiple apertures are selected at the time of purchase the result is a flexible system that can measure a wide range of spot sizes without changing the working flexible distance to focus the MS-55 lens. Variable apertures and a wide selection of objective lenses make it possible to measure virtually any target size down to 0.02 mm. Because the measuring aperture is the entrance slit to the spectrometer, the instrument bandwidth depends on the aperture used. In order to measure narrow band sources such as laser diodes, small apertures (1/4° or 1/8°) should be chosen to obtain a BW of 2.5 nm. The PR-705/715 is the most sensitive instrument in its class and can measure incandescent sources at light levels as low as 0.001fL (0.003 cd/m2). It can even measure the black levels required to characterise the contrast ratio of various displays. This new SpectraScan is almost a hundred times more sensitive than it's predecessor. Remote Operation and Data Transfer The measured data can be stored on a 3-1/2" on-board floppy diskette and easily transferred to a computer for further analysis. Remote operation from user-defined software running on a host computer is possible by sending ASCII commands over an RS-232 port to control the PR-705/715 (built in Remote Mode software). A built-in centronics parallel port is available for connecting to standard PC printers and a SYNC IN/SYNC OUT connector is provided for pulsed light measurements. The PR-705/715 can be operated from a PC using SpectraWin™ software. SpectraWin™ is Windows-based software that gives you the power to make measurements, view data in customized graphics displays, perform calculations on stored data and create macros for automation.
