Rolera Bolt USER MANUAL

GLOSSARY

C-Mount
A standard threaded lens mount used to attach a camera to a microscope, or a separate lens to a camera.
CMOS
Complementary Metal Oxide Semiconductor (abbr.)
CMOS Gain
The amount of analog signal amplification. The gain is factory-optimized for the camera's maximum dynamic
range.
Complementary Metal Oxide Semiconductor
The light sensitive silicon chip near the optical interface of the camera that converts light intensities into
electrical signals. These are typically made up of many pixel elements whose intensities are interpreted by
imaging software to display an image on the screen.
Dynamic Range
The ratio of the saturation level of the CMOS to the readout noise of the CMOS camera system. Dynamic
range is a measure of the ability of the camera to capture both bright and dark features in a single image. In
general, the higher the camera's dynamic range, the more information per pixel it can capture.
Exposure
The amount of time that light reaches the image sensor.
Field of View
The area visible through the camera's optics.
Integration
The active collection of photons as done by an image sensor.
Iris
A diaphragm in the lens that opens or closes to set the aperture (the amount of light that passes through the
lens to the CCD).
