LIRIS detector properties |
|
|
|
|
|
|
|
|
|
Detector size |
1024 x 1024 pixels |
|
|
Full-well capacity |
100000-150000 e- |
|
|
Spectral range |
0.85-2.5 μm |
|
|
Quantum efficiency |
90% (K), 80% (J) |
|
|
Readout noise (CDS) |
< 10 e- |
|
|
Readout noise (MNDR) |
< 3 e- |
|
|
Gain |
3.5-3.7 e- / ADU |
|
|
Pixel size |
18.5 μm |
|
|
Pixel scale |
0.250" / pixel |
|
|
Field of view |
4.27' x 4.27' |
|
|
Bad pixels |
~1.5%, almost all of them located at the very detector edges |
|
|
Linearity |
< 2% within 25000 ADU, drop to 15% within 35000 ADU. For very low illuminations (few 100 ADU), the detector is undersensitive (see the linearity
over the 4 sections of the detector here).
|
|
|
Charge persistency |
< 1%, disappears after two or three detector reads |
|
|
Saturation limit |
45000 ADU (before Dec. 2006: 35000 ADU) |
|
|
Dark current |
~ 0.065 e-/s at 83 K |
|
|
Readout time |
0.9 s |
