Gamma Scientific [ @gammascientific ] has just introduced two new instruments for display measurements. Both offer colour, intensity and flicker testing of all types of LED, LCD, OLED and Quantum Dot screens.
The GS-1160 is the touchscreen-equipped handheld version, while the GS-1160B is designed for the bench and operates in conjunction with PC-based analysis software. The GS-1160 can also be used as a desktop system as it is supported by the same software.
These spectroradiometers, to give them their proper name, deliver faster results with repeatability superior to filter-based instruments. Additional measurement capabilities include gamma, white balance and uniformity.
Data is output on both via USB, or can also be stored on an SD card in the GS-1160 portable model. The GS-1160B can be programmed for custom testing as it has an Application Programming Interface (API). Commands can be sent via RS-232 or the USB.

The recently introduced SpectralLED™ tunable light source from Gamma Scientific combines the light of dozens of discrete LEDs – each having a different centre wavelength – to produce output that can be programmed to closely match virtually any illuminant source or the spectrum of any illuminant reflected by a target.
Now new SpectralLED™ models are available with either fibre-optic outputs for awkward to reach places requiring illumination, or as a 1 m integrating sphere system offering ultra-uniform output from a 300 mm diameter port.
Gamma Scientific has also introduced new display measurement instrumentation equipped with powerful spectral data acquisition and analysis software that makes them ideal for calibrating any type of display…

Organic Light Emitting Diodes (OLED) – the next generation of displays and light sources – have an emissive electroluminescent layer that consists of organic molecules in a supporting matrix. For full colour, high resolution displays, this layer is formed into millions of microscopic pixels in ordered rows and columns.
The biggest advantages of the OLED devices, unlike the traditional Liquid Crystal Displays (LCD), is that the pixels combine both the light source and the colour source making them lighter, thinner and more energy efficient. However, the consistency of the intensity and the colour of the optical emission across the device is critical, so this is where instruments such as the CRAIC’s 308 FPD™ are used.
The 308 FPD™ spectrophotometer is designed to measure and compare the spectral output, intensity and colour consistency of each microscopic pixel in milliseconds, thereby quickly creating spectral maps for a whole device and ensuring quality control is maintained.
CRAIC Technologies is a global technology leader focused on innovations for microscopy and microspectroscopy in the ultraviolet, visible and near-infrared regions. Their 308 FPD™ spectrophotometer is designed to be added to the open photoport of a microscope or probe station and is one of a number of their spectrophotometer instruments available through Elliot Scientific for customers in the UK and Ireland.
