The dimensions of a high QE PDs was measured as well as the ones for C30665. (Attachment 4, Unit in mm)
They seemed to be very much compatible.
The PDs came with the designated case (Attachment 1). The bottom of the case has a spongy (presumably conductive) material.
Diodes have no window. Each came with an adhesive seal on it. (Attachment 2)
There is a marking of a serial at the side.
I opened one (Attachment 3). The sensitive area looks just beautiful. The seal was reapplied to avoid possible contamination. |
