This microscopic scale and sensitivity allows the sensor to map a high-resolution image of electrical charge that occurs over the surface of a source material (for example a human finger), when it makes contact with a thin insulating surface (ie a plastic surface).
Thanks to the incorporation of a newly designed back-illuminated CMOS imagesensor with outstanding high sensitivity and low-noise characteristics, the PENTAX Q10 delivers high resolution images with approximately 12.4 effective megapixels, and a top sensitivity of ISO 6400.
