Vacuum Sealing Adds Life to Scientific CCDs

Facebook X LinkedIn Email
How the sensor is packaged influences both its life span and performance.

Dr. Hugh Cormican, Andor Technology

Perhaps a key question for any scientific imaging application is how long the CCD camera will last before the chip underperforms. One major “camera killer” is condensation on the chip. Most cameras leave the factory virtually blemish-free, but over time, they pick up moisture, hydrocarbons and other gas contaminants. CCD performance will then decline proportionally. Eventually, it becomes so poor that the camera is virtually unusable. One way to preserve the integrity of the chip is to house the sensor in a vacuum environment. However, it is important to understand that all vacuums are not...Read full article

    ccd camera
    A CCD camera, or charge-coupled device camera, is a type of digital camera that utilizes a CCD image sensor to capture and record images. CCD cameras are widely used in various applications, including digital photography, scientific imaging, surveillance, and machine vision. CCD camera suppliers → The key components of a CCD camera include: CCD image sensor: The heart of a CCD camera is the CCD image sensor, which is a semiconductor device consisting of an array of...
