Product Release
The Tucsen developed semiconductor refrigeration CCD photoelectric detection system has passed the identification of new products in Fujian province.
Tucsen developed semiconductor refrigeration CCD photoelectric detection system, the system uses large area array CCD chip, combined with the semiconductor refrigeration technology and characteristic of the low noise circuit design. The effective exposure time and ordinary CCD camera can be extended to the level of hours to achieve to fluorescence, luminescence, infrared high sensitive detection.
The experts come from the analysis of chemical, optical physics, electronics, instruments, quality inspection and other industries. We listened carefully to the report of the Tucsen technical director Mr. Yu Qiang, reviewed the relevant technical information, watching the demonstration of the product, the product of the low noise circuit gave a high evaluation. The CCD noise is composed of the photon shot noise, the readout noise, and the dark current noise. While the readout noise, dark current noise is the key indicator of CCD detection system. Tucsen CCD detection system, through a number of specific noise reduction techniques, such as semiconductor refrigeration, correlation double sampling, frequency technology, anti glow technology. Greatly reduce the noise of the products, and foreign similar products such as: the United States of America Roper and Germany VDS in the comparison, slightly dominant. In the readout noise reached the level of 4e. In the dark current noise reached the level of 0.25e/s, better than similar foreign products. Has been widely recognized by experts.
Experts agreed that: the project development of high technology content, reached the domestic leading level. In the scientific instruments, medical testing, astronomical photography and military and other aspects have a huge application value. Has a good application prospect in food safety testing, environmental monitoring, criminal investigation and hospital disease screening etc.. More Tucsen digital microscope products
