ultrafast PIN photodiodes have certain advantages over vacuum photodiodes.
Besides the compact size and low-voltage power supply, they feature higher sensitivity, which is typically two orders of magnitude larger in the near infrared as compared to vacuum photodiodes.
Our UV-extended version is the only commercial photodiode that covers the spectral range from 190 nm to 1100 nm and has risetime below 200 ps.
Because of the extremely low dark current, the built-in high-power battery provides trouble-free operation for UP TO FIVE YEARS*! In combination with our ult...
