  • Dual-CCD Camera

Feb 2010
Hamamatsu Photonics UK Ltd.Request Info
The Orca-D2, a high-sensitivity camera for simultaneous dual-wavelength imaging, is available from Hamamatsu Photonics UK Ltd. Featuring two CCD devices and interchangeable optical blocks, the camera delivers ease of use with optical setup steps, including image alignment and focusing. It provides a wide field of view during wavelength imaging and delivers high sensitivity, low noise and a wide dynamic range. Its proprietary vacuum-sealed chamber technology promotes long-term, maintenance-free operation for demanding applications. It is suitable for Förster resonance energy transfer, ratio imaging and dual-wavelength total internal reflection fluorescence.

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 emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
1. The focal point. 2. To adjust the eyepiece or objective of a telescope so that the image is clearly seen by the observer. 3. To adjust the camera lens, plate, or film holder so that the image is rendered distinct. 4. To move an entire microscope body tube relative to a specimen to obtain the sharpest possible image.
The unwanted and unpredictable fluctuations that distort a received signal and hence tend to obscure the desired message. Noise disturbances, which may be generated in the devices of a communications system or which may enter the system from the outside, limit the range of the system and place requirements on the signal power necessary to ensure good reception.
In a radiation detector, the ratio of the output to the input signal.
