PROFESSIONAL CCD SONY EX-VIEW HAD SENSOR ANALOG VIDEO C

In the field of surveillance cameras and on-board cameras, there are needs to film with high sensitivity in not only light but also in dark environments. To answer these needs, Sony has developed the new structure "EXview HAD CCD", which is capable of detecting with great sensitivity near infrared light region which is unable to be discerned by the naked eye. Light in the near infrared light region which has long wavelengths is converted into photoelectricity deep in the semiconductor's silicon, so in conventional CCD structure, sensors were incapable of efficiently gathering the charge which has undergone photoelectric conversion. This "EXview HAD CCD" structure has made it possible to use as video information the charge of near infrared light which was hitherto invalid. This resulted in a dramatic region improvement in sensitivity. This in turn made it possible to film in the dark by radiating near infrared light which is invisible to the naked eye onto the object being filmed, which opens up applications in a broad range of applications, such as surveillance cameras, on-board cameras and scientific measurement cameras.
