Optic probes for measuring radiance & luminance
To be able to match the best optical probe to customer’s needs, it is important to know what the client has to measure, which quantities they need to deliver, how wide a spectral range has to measure in and which measuring area diameter will be satisfied with.
GL Optic offers variety of optical probes for luminance/radiance measurements. They differ in spectral range and a type of optic fiber.
Ready-set-go
Each complete set includes a measuring probe, a fiber optic cable, and adapter for a dedicated spectrometer. Includes calibration traceable to national laboratories.
Smart detection
All GL Optic Spectrometers include smart system of detection that automatically detects a new probe and loads the appropriate calibration file.
Extended spectral range
Constructed of high transmission quartz fiber optics, these optical probes can cover a broad spectral range from UV to NIR (200-1050 nm).
GL OPTI PROBE 1.0.10 Luminance Usage
This accessory is intended for measuring luminance [cd/m2] of flat LCD and OLED panels and plasma FPDs. Typical devices to be tested are: television screens, computer monitors, avionics displays and other electronic displays and where there is a need to measure reflective surfaces – also walls and workplaces, projection screens and signs.
This optic probe measures the light emitted in a particular direction by a given spot on the surface of a relatively large or extended source. The measuring probe can be installed on a tripod for distance measurements or directly on a screen with the use of a special stripe for contact measurements. The optic probe connects to GL SPECTIS 1.0 or GL SPECTIS 1.0 Touch. The probe comes with polymer fiber optic cable. Usable spectral range: 400-730 nm.
