Light Measurement Testing Applications

Since 1961 Gamma Scientific has produced LED, display and light measurement test solutions for production and R&D environments.

With over 50 years of innovation in light measurement and metrology, Gamma Scientific instruments are trusted by leading global organizations that require high-speed, precision measurements and custom configurations for the most challenging environments.

Based in San Diego, California, Gamma Scientific manufacturers laboratory grade spectroradiometers, spectrometers, integrating spheres, spectrophotometers and light sources.

Gamma Scientific also operates a NVLAP accredited laboratory (NVLAP Lab Code 200823-0) that performs ENERGY STAR® lighting certification and LM-79 testing.

LED Testing

Gamma Scientific produces complete solutions for LED Testing, including spectroradiometers, spectrometers, integrating spheres and turn-key LED binning instruments.

Thin Film Measurement

Gamma Scientific’s Thin Film Measurement Systems provide isolated first surface measurement of anti-reflection coatings to 0.5 mm thick.

Gamma Scientific’s unique technology allows manufacturers to perform single sided inspection on the first surface of any glass or polished, transmissive element while excluding the second surface.

Display Measurement

Custom Display Measurement solutions are available to calibrate monitors, video walls, near-to-eye displays and 3D screens. Gamma Scientific also provides equipment to test LEDs, light engines, color filters, back lights and display glass. Display test systems from Gamma Scientific include high-speed spectroradiometers, spectrophotometers, colorimeters and goniometers.

Photometry

UDT Instruments, a division of Gamma Scientific, offers an extensive selection of photometers, lux meters, luminance meters, illuminance meters and optical sensors to meet your photometry testing needs. Combining our wide range of optometers, photometric sensors and accessories, with our state-of-the-art calibration facilities, allows our applications engineers to assemble and configure custom photometer systems for nearly any project.

Radiometry

Radiometry is the measurement of radiation in the electromagnetic spectrum. This includes ultraviolet (UV), visible and infrared (IR) light. UDT Instruments produces a large selection of customizable radiometers, radiance meters, irradiance meters and optical sensors for radiometric testing applications.

Night-Vision Compatibility Testing

For over 40 years Gamma Scientific has been a pioneer in night vision testing. Gamma Scientific offers a comprehensive line of instruments specifically designed for ANVIS testing of cockpit displays and night vision goggles that exceed requirements outlined in MIL-L-85762A and MIL-STD-3009.

Fiber Optic Testing

UDT Instruments offers fiber optic test systems optimized for operation at essential telecommunication wavelengths, as well as most common laser and laser-diode wavelengths. Other UDTi test systems are designed and calibrated to operate over a wide spectral range in order to support diverse applications with a single system.

Camera Calibration

Gamma Scientific’s line of LED light sources for camera calibration combine light-emitting diodes (LEDs) with linear programmable drive circuitry and active optical feedback to provide precisely controllable, programmable light output. Eigenlite™ Digital Uniform Light Sources exhibit excellent linearity, repeatability, and long-term stability.

Laser Measurement

The UDT Instruments division of Gamma Scientific offers solutions for measuring the optical power of lasers and laser diodes operating at wavelengths in the UV-VIS-NIR range (350 nm – 1800 nm) and at low to medium power levels (from < 10 nW to over 30W). Our laser measurement systems can also be configured to support “single-shot” energy measurements of individual laser pulses.

Highway Safety

RoadVista, a Gamma Scientific company, has set the standard in retroreflectometer accuracy, reliability and usability. With over three decades of highway safety leadership, RoadVista is committed to making roads visibly safer with complete retroreflection solutions.

Optical Calibration and Metrology

Gamma Scientific operates a NVLAP accredited laboratory under the Energy Efficient Lighting Products Program that includes LM-79 accreditation for Solid State Lighting Luminaires. The laboratory offers comprehensive light measurement services, including third party ENERGY STAR certification for lighting products.

Position Sensing

Our extensive selection of optical position sensors, position amplifiers/indicators, and accessories allows our applications engineers to assemble and configure a tremendous variety of position sensing systems.
