PSDs are optoelectronic position sensors that utilize photodiode surface resistance. Unlike discrete element detectors such as CCDs, PSDs provide continuous position data, high position resolution, and high-speed response.
One-dimensional PSDs have a long, narrow photosensitive area and detect positions in a longitudinal direction. Suitable for use in displacement meters and other high precision distance measurement applications, such as optical switches.
PSDs for two-dimensional position detection are available in double-sided and front-side segmented models.
Easy-to-use PSD modules integrate our PSDs with a current-to-voltage conversion circuit.

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 are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. 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.
