Image intensifiers are devices that can detect and amplify very low levels of light to capture images.
They are used in a wide range of applications, including imaging of micro-discharges in the invisible regions and observation of high-speed phenomena.
The V7669U is multialkali photocathode image intensifier with spectral response range from 160 nm to 900 nm and an effective photocathode area of Φ25 mm.

1. What are cookies?
For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently.

Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
