Red Enables Cell Membrane Study
|
From PCO AG
In biological microscopy, simply being able to view a sample is half the battle. It is also crucial to capture and archive images for future reference. CCD cameras seem to be the technology of choice for this task, but not all of these devices are the same. Various microscopy applications demand cameras with appropriate technological features, such as adequate color sensitivity, speed, resolution or even physical specifications. Researchers at the University of Virginia in Charlottesville recently attempted to find a CCD camera to facilitate their study of the varying states of phospholipid bilayers that mimic cell membranes. They wanted to create and image in vitro membrane models tagged with the fluorescent dye rhodamine. To capture the images, they needed a camera that not only has a high sensitivity to rhodamine's red light, but also offers the standard advantages of a CCD device. Products & Services
Video cameras take continuous pictures and generate signals for display or recording. They capture images by breaking them down into a series of lines. This search form does not include consumer devices such as camcorders.

Charge coupled device (CCD) cameras contain light-sensitive silicon chips that detect electrons excited by incoming light. They also contain micro circuitry that transfers a detected signal along a row of discrete picture elements or pixels, scanning the image very rapidly. CCD cameras use two-dimensional CCD arrays with many thousand of pixels.

Complementary metal oxide semiconductor (CMOS) cameras use image sensors that operate at lower voltages than charged coupled devices (CCDs), reducing power consumption for portable applications. Each CMOS active pixel sensor cell has its own buffer amplifier, and can be addressed and read individually.
