Human vision and recognition - but a thousand times faster
With the SPECTRO-3 series there now is a family of color sensors that has been specifically designed for "true-color" detection ("human color reception") and high switching frequency. The sensors can be operated both in AC and in DC mode, with integrated or external light source. With the included SPECTRO3-Scope software illumination can also be turned off with a simple mouse-click, which then also allows the color and brightness inspection of self-luminous objects such as LEDs, automobile tail lights, halogen lamps, or fluorescent lamps. Up to 31 colors can be provided through the 5 digital outputs, the maximum switching frequency is 30 kHz.
Apart from a super-bright white-light source, a high-performance UV light source also is available, which allows a color and brightness differentiation of fluorescent colors without any problems. Different optical frontends make it possible to implement operating distances of almost 0 mm up to 500 mm, with detection areas of Ø 0.5 mm to approx. Ø 100 mm. The use of an optical fibre version allows applications in Ex areas.
In combination with a reflected-light optical fiber and a neutral-absorber attachment unit the SPECTRO-3-FIO (version for use with fiber optics) makes it possible to perform a color inspection of different self-luminous objects.
