IdealPhotonics' sCMOS miniature microscope camera, with 2.1 megapixels, is a high-performance, compact imaging device employing a scientific-grade back-illuminated CMOS sensor. Its low noise (including back-illuminated sensor quantum efficiency (QE>90%), readout noise (<1e-), frame rate (40-100fps), dynamic range (16-bit), and pixel size (6.5µm large pixels) collectively ensure its single-photon sensitivity and high temporal resolution in low-light imaging.
