High-sensitivity cameras are preferred because they can detect and capture extremely low light signals and enhance both image quality and experimental flexibility in digital microscopy, overcoming limitations in traditional microscopy.
A visible light camera is a type of imaging device designed to capture pictures or video using only the visible portion of the electromagnetic spectrum (approximately 400–700 nanometers in wavelength), which is the same range detectable by the human eye.
Ultra-low read noise: sCMOS read noise approaches 1 e⁻, far outperforming traditional CCDs.
High frame rate: Parallel readout architecture supports 100 fps or higher.
Wide dynamic range: Captures bright and dark regions simultaneously with ratios up to tens of thousands to one.
Large field of view and high resolution: Suits high-resolution, wide-field imaging.
They are used widely in biological microscopy, fluorescence imaging, fast object inspection, astronomy, X-ray imaging, cold atom research, and other precision-science scenarios.
