S6795 and S7747 are 6-element Si PIN photodiodes molded into clear plastic packages. These photodiodes feature high sensitivity, low noise
and low cross-talk. S7747 is specifically developed for violet laser detection, providing greatly improved sensitivity at
l=410 nm.
Custom-designed devices (with different element shapes, number of elements, characteristics and packages) are also available to meet your
specific needs. Feel free to contact our sales office.
