PSD (Position Sensitive Detector) is an optoelectronic position sensor utilizing photodiode surface resistance. Unlike discrete element detectors such as CCD, PSD provides continuous position data and features high position resolution and high-speed response.
|Photosensitive area||4.7 x 4.7 mm|
|Peak sensitivity wavelength (typ.)||920 nm|
|Photosensitivity (typ.)||0.6 A/W|
|Spectral response range||340 to 1060|
|Dark current (max.)||5 nA|
|Rise time (typ.)||0.3 μs|
|Terminal capacitance (typ.)||45 pF|
|Interelectrode resistance (typ.)||10 kΩ|
|Measurement condition||Typ. Ta=25 ℃, unless otherwise noted|

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.
