Despite a 20 um overhang this is an outstanding device with high QE. Glowing on top 50 lines out.

Given on loan to Danish people (DFOSC) in September 1999, should be shipped back in Garching at some point. Danish people may have killed this device. Tested here looks dead....

This device has not been thoroughly tested due to charge injection from the wiping drain. VDD must be reduced.

Not so nice for a science grade...! Beware ! VDD (Drain) must be 11V and VDR = 24 V (otherwise massive Glowing will occur) |

Nice Eng grade device, It looks like that E2V has used a trick to reduce IR fringing, because IR fringing is different than usual.

E2V said that this device has 82 traps ... it turns out to be a very nice science grade usable for spectroscopy... mistake from them ? Yes ! Indeed, this is 8462-13-2 instead of 8462-14-2, shipped back to E2V.
