Overview
The ORCA®-Halo is a routine camera with a back-illuminated sCMOS sensor. Although it is a routine model, it offers high sensitivity and resolution, as well as a wide field of view and low readout noise. This camera can be used for a wide range of applications and is designed for those who want to obtain high performance easily and integrate it into their equipment.
ORCA is a registered trademark of Hamamatsu Photonics K.K. (China, EU, France, Germany, Japan, UK, USA).
