Gamma Scientific Display Test Systems
Display Reflectance Spectrophotometer
High speed spectrophotometer system for testing thin film optical coating reflection on displays. Integrates with production line equipment for high speed testing and maximum uptime.
The Display Reflectance Spectrophotometer captures precise, repeatable measurements of the antireflective optical coating on displays. With the option of excluding other reflective layers behind the first surface, the spectrophotometer provides unprecedented accuracy and versatility.
Rapidly captures the spectral measurements for displays with industry leading accuracy.
High sensitivity with superior color, linearity and amplitude accuracy.
Six-axis robotic arm and spectroradiometer captures measurements from any user specific angle while the display remains stationary. Quick and easy set-up.
Laboratory grade accuracy with dual LCD/CRT measurement capability. Calibrates LCDs, LEDs, plasmas, video walls and projection screens for color accuracy, uniformity of brightness and white balance. Unprecedented portability and affordability.
The 191 Gonioreflectometer Heads measure the spectral reflectance of surfaces over the range of 380 to 1100 nanometers. Different models cover both specular reflectance, and diffuse reflectance, or both.
Exceptional accuracy, low maintenance and near real-time measurement for NVIS testing of cockpit displays and lighting. Exceeds all requirements outlined in MIL-L-85762A and MIL-STD-3009.
UDT Instruments Luminance Meters
UDT Instruments, a Gamma Scientific Company, produces handheld and benchtop luminance meters to provide non-contact measurement of an area on display surfaces.
