Photo Research, a JADAK brand, is the world leader in high precision, state of the art optical instrumentation and systems. For over 75 years, Photo Research has delivered world-class light and color measurement solutions. Photo Research color and light measurement products are used in the cathode ray tube (CRT) and flat panel display, automotive, aerospace, motion picture, and research and development industries.
Photo Research product lines include:
Spectra, used for research, quality control and on-line testing. This line includes the portable, battery-operated Spectroradiometer and the fast scanning SpectraColorimeter. The PR-730/735 SpectraScan is the industry's first automated aperture wheel, with up to six apertures. The Pritchard line is the most widely used photometer in the world. Photo Research developed the first commercially available video photometer. Video instrumentation provides high resolution inspection of CRT, flat panel displays and instrument panels. The Photo Research Optical Metrology Laboratory (PROML) is a supplier of and service provider to optical radiation standards, calibration and measurement for major manufacturers of instruments, displays, devices and materials. All Photo Research instruments are calibrated to NIST-traceable standards. Photo Research developed many industry standards, such as the Spectra Pritchard Optics, which is utilized in astronomical and star-simulation measurements. Photo Research also supports standards for organizations including VESA, ISO and SAE.
Since 1941, Photo Research has made significant contributions to the field of photometry and spectroradiometry, the science of measuring the characteristics of light. The company was founded as Photo Research Corporation by Karl Freund, a well-known cinematographer, who began developing products to improve the quality of photography in the motion picture industry early in his career. His products, the Spectra® Color Temperature Meter and a direct reading brightness meter, received two Academy Awards for technical achievement from the Motion Picture Academy of Arts and Sciences.
Photo Research's market grew as other industries learned of the usefulness of accurate light measurement. When aircraft manufacturers required a special luminance meter with close-up optics that could precisely measure the brightness and color of aircraft panel displays, Photo Research developed the first Spectra SpotMeter. This instrument helps engineers to design and develop light-emitting products such as aircraft instruments and panels, automotive instrument panels, tail lights and headlights, motion picture screens, flat panel displays and cathode ray tubes.
In 1960, Photo Research developed the Spectra Pritchard Photometer with the help of Dr. Ben Pritchard, a well-known authority in the field of light measurement. Also an industry standard, the Spectra Pritchard Photometer is protected by three U.S. patents. The product's sophistication lent itself to many new applications, including astronomical and star-simulation measurements and human factors testing.
During the 1970's. Photo Research received four additional Academy Awards from the MPAAS for products as diverse as the film-lens balanced Three Color Meter and the Spectra Film Gate Photometer for motion picture printers.
The last decade has seen Photo Research's famous optical designs miniaturized to affordable products, offering the precision of laboratory table-top instruments with the convenience of light-weight, microprocessor controlled portability.
