Product catalog summary
User Defined CIE Pass/Fail Criterion
The CIE Pass/Fail option allows the SpectraScan series to function as a 'GO / NO GO' color tool. Users can define acceptance regions in various shapes such as ellipses, rectangles, or polygons on the CIE 1931 Chromaticity diagram. Measurements falling within these regions display 'PASS', while those outside display 'FAIL'. This feature is supported by devices like PR-655, PR-670, PR-680/l, PR-730/735, and PR-740/745 SpectraScan.
Color Rendering Index (CRI)
The CRI feature compares different light sources by evaluating their ability to render colors accurately. It uses fourteen reference colors, with the first eight calculating the average CRI. Users can select or auto-generate the reference source. Supported devices include PR-680/680l SpectraScan and PR-805/810 Pritchard.
3D/Temporal Analysis
With the rise of 3D technologies, accurate calibration is essential. Photo Research's 3D Ready instruments facilitate the characterization of 3D systems, minimizing polarization errors to less than 1%. These devices feature a high-resolution touch screen for easy navigation and analysis. Users can interact with the display to analyze specific points on a graph.
Noise Rejection Filters
3D ready instruments include frequency response filters that reject high frequencies and average signals electronically. These filters operate at various frequencies, such as 50KHz, 20KHz, 600Hz, 200Hz, and 10Hz, aiding in the characterization of rise and fall times, peak and valleys, dynamic contrast ratio, cross talk, and shutter frequency.
Flicker Analysis
Flicker characterization is performed per VESA FPDM standards, with data displayed on a full-color touch screen. Users can evaluate flicker characteristics at various frequencies by interacting with the graph. This feature provides detailed information on flicker components and modulation amplitude.

photo research®, inc. Spectrascan®/Pritchard® Advanced Options user defined cie pass/fail criterion The CIE Pass/Fail option provides a convenient means of using the SpectraScan series as a "GO / NO GO" color tool. Using CIE Pass / Fail, you can create an acceptance region of various shapes and sizes. Rgions can be defined as Ellipses (or circles), Rectangles (or squares) or polygons (3 - 10 sides). After a measurement, chromaticity points that fall within the defined region cause the message "PASS" to be displayed on screen, and if the measured point is outside the region, "FAIL" is displayed. Regions are defined in the CIE 1931 Chromaticity diagram in x, y coordinates. color rendering index* (cri) Comparing two light sources? Use the Color Rendering Index feature for comparisons between different light sources. Color Rendering Index is a good metric for testing luminaires or other light sources for their capability to render the color of an object being illuminated by that source with respect to a reference light source. Fourteen reference colors are used to determine the similarities between the test light and the standard with the first eight colors being used to calculate the average CRI. Users can select or automatically generate the reference source. □□□□□□□□ cie color chart Diagram with mea- Displays full color CIE 1931 Chromaticity sured point following a measurement. supported devices > PR-655 SPECTRASCAN > PR-670 SPECTRASCAN > PR-680/L SPECTRADUO > PR-730/735 SPECTRASCAN > PR-740/745 SPECTRASCAN

3d/ temporal analysis* As increasing popularity drives demand for 3D technologies across media and entertainment industries, so too does the need to characterize and calibrate thse Systems. Gone are the days when the calibration of displays or projector Systems could 3 D rely on the 'magie eyeball'. Correct adjustment and vrification requires accurate and repeatable measurements. When the proper tools are utilized the required tests can be conducted in a timely manner and insures that the images being displayed, regardless of the technology, are the best possible.
