The Titan system is an imaging colorimeter with an integrated NIST-traceable calibrated spectrophotometer and a fast sampling light meter, combining three fundamentally different devices into one solution giving it unprecedented capabilities and flexibility.
Within the lighting industry various technologies are being used to create large surface ceiling or wall lights. These large luminous surfaces are often designed to be attention catchers as well. These can be switched to multicolour modes where the surfaces can be programmed to show multicolour pixelated visual content. In most cases LEDs are used as a light source. LED technology requires the use of electronic current drivers. Poorly designed or manufactured these drivers may cause flicker which can be annoying, cause headaches and even trigger epileptic seizures. For that reason it is very important for any lighting application to measure flicker, especially when used in an office or home environment.
Qualifying any new product design [by validating prototypes] requires accurate measurements in the laboratory. After the product design has been validated in the laboratory the product will be manufactured. Technologies such as back-lit textiles, back-lit diffuser sheets or [flexible] OLED panels face uniformity issues caused by production variations. Any non-uniformities need to be measured. The Titan series can be used in both laboratories and manufacturing facilities to qualify, test and adjust their luminous surface products according to the highest standards. Typical measurements are:
- Flicker: the Titan can measure flicker according to various standards, including flicker percentage, flicker index and the IEEE 1789 recommendation for current modulation in LEDs.
- Start-up behaviour: the high-speed light meter module can measure how the light source starts immediately after power-up.
- White point adjustment (RGB multicolour LEDs only): the integrated NIST traceable spectrometer guarantees that the camera produces accurate and repeatable luminance and colour data which can be used to tune the white point of the RGB LEDs.
- Multipoint luminance and colour measurements: multiple regions can be defined to measure the luminance and colour of predefined areas. Examples are 5- or 9-point measurements.
- LED panel modules can be adjusted on single (RGB) pixel level since all colour information of every RGB pixel is measured.
Like all Admesy devices the Titan is designed for quick integration into a production environment because of the robust mechanics, reliable electronics, and production-ready software architecture. With the [free] software suite the Titan can be easily used in the laboratory.
