NIR Camera

Oct 2010
Vision Components GmbHRequest Info
For demanding machine vision applications, Vision Components GmbH has released the VC4467/NIR sensitive image processing systems in the shape of a fist-size camera. The cameras feature an EXview HAD CCD sensor from Sony that detects both visible light waves and long-wave light near the infrared spectrum. They ensure precise image recording, even in low-light conditions. The sensor has been modified to further increase sensitivity in the near-infrared range and, as a result, the cameras produce high-quality data at wavelengths up to 1100 nm and are suited for tasks such as electroluminescence quality control in the photovoltaic industry. Monitoring the production of solar cells, they reliably detect and identify defects such as microcracks, shunts and disconnected fingers. They can independently run functions such as motion detection and license plate recognition. Optional robust housings provide protection for outdoor applications.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
The nonthermal conversion of electrical energy into light in a liquid or solid substance. The photon emission resulting from electron-hole recombination in a PN junction is one example. This is the mechanism employed by the injection laser.
In optics, an image is the reconstruction of light rays from a source or object when light from that source or object is passed through a system of optics and onto an image forming plane. Light rays passing through an optical system tend to either converge (real image) or diverge (virtual image) to a plane (also called the image plane) in which a visual reproduction of the object is formed. This reconstructed pictorial representation of the object is called an image.
1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
