详细介绍
The Model 830 SC200 CCD camera is a new member to the ORIUS familly of high performance CCD cameras. It is a 2k x 2k CCD (4M pixels) camera designed to deliver extraordinary resolution and TV readout speed for imaging applications in both life and materials science. The combination of HCR (high-contrast resolution) optical technology, and advanced CCD readout electronics has given the SC200 camera the best price-performance value.
This camera which is offered in both 35mm and bottom port configurations can also provide a high resolution view of the sample making it ideal for use in materials science imaging applications and life science applications such as small particles, cryo, low dose and viruses. The side mount configuration is offered to 120kV TEM’s only. The side mount option provides a large field of view of the sample suitable for imaging applications in general life science.
The SC200 can output high quality (gain normalized) LIVE images that are corrected for cosmetic defects or shading.
