The PixelSensor? multispectral sensor uses a unique technique of creating filters directly on the chip's encapsulating glass, allowing up to eight photodiodes of a choice of wavelengths to be packaged in a compact 9 x 9 mm array, resulting in a simpler and smaller optoelectronic device. One PixelSensor can replace multiple components, helping to reduce the size of multispectral instruments for applications such as in vitro diagnostics, biochemical testing and chromatic analysis.
The unique wafer-level optical filter divides the spectrum into eight separate colour bands, improving contrast and sensitivity by suppressing the background light outside the bands. The customer can define the desired spectral band and we will customise it on behalf of the customer, with a choice of narrow band spectral bands ranging from visible to near infrared. In addition, the option to require an OEM circuit board, designed for easy integration into the customer's analytical instrument, is a cost-effective solution with smaller dimensions (45.72 x 21.34 mm) and faster time to market than conventional sensor technology. The parallel channel design avoids moving parts and allows for faster measurements than discrete optical designs and spectrometers. 20-pin LLC packages are designed for low noise and fast response and can be surface mounted or cartridge mounted.
PixelSensor's foundry circuit board and other accessory options and easy-to-use software interface provide designers with an effective tool for rapid prototyping and product development - helping them to progress quickly from design concept to volume production.
