The TOP 300 optical probe is primarily used for quality tests of AR/VR/MR modules in the production line or development. It performs highest accuracy color and luminance single spot measurement within an AR/VR/MR headset.
The innovative mode mixer from Instrument Systems ensures stable transmission through the fiber and thus reproducible measurement values, even when the fiber is moved on a positioner or goniometer. The compact TOP 300 design is ideal for mounting on a positioner/robot.
The TOP 200 telescopic optical probe is based on Pritchard optics with an integral viewfinder camera.
The TOP 150 is a low-cost alternative with a single aperture.
The measured radiation density is coupled into the spectrometer by the TOP 200 via a multimode fiber. The patented mode mixer from Instrument Systems ensures uniform light transmission in the fiber and thus reproducible readings, even when the position of the fibers is changed.
The Pritchard principle enables the field of view to be observed during measurement and monitored for exact positioning. The image of the viewfinder camera is automatically imported by the SpecWin Pro software and saved with the readings.
Instrument Systems has developed various measurement adapters for determining the averaged luminous intensity ILED-B [cd] of LEDs. These differ according to the usable spectral range (only visible or also UV), measurement geometry and planned application (in the lab or production).
Measurement adapters contain a diffusor that forms the sensitive detector surface of precisely 1 cm². Behind the diffusor is an optical fiber bundle, with the aid of which the light beam is coupled into the spectrometer. This design is characterized by high light throughput with sufficient homogeneity of the detector surface. The LED-4xx series of measurement adapters is thus particularly suitable for low-light LEDs and use in fast production tests.
LED 4xx measurement adapters can accept all test sockets of the LED 5xx, LED 6xx and LED 81x series. A clamping mechanism ensures reproducible and exact alignment of LEDs at all times. Shortened versions of the measurement adapters are available for use in production (e.g. for mounting on an LED handler).
For applications requiring the highest degree of precision, optical probe LED 25 was developed for determining “averaged LED intensity” according to CIE 127. The latter is based on an integrating sphere and thus offers homogeneous light sensitivity over the whole detector surface, albeit with a reduced light throughput.
