Si photodiode array
The S4111-46Q is a Si photodiode linear array mounted in a ceramic DIP (Dual Inline Package). This photodiode array is primarily developed for low-light-level detection such as spectrophotometry, and cover a wide spectral range from UV to near infrared light. Since all elements can be used with a reverse bias for charge storage readout, The S4111-46Q is able to detect low level light with high sensitivity. Cross-talk between elements is minimized to maintain signal purity. Special filters can be attached as the input window (custom order products).

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.
