Selectiegids
| Detectorformaat | Typische rol | Beschikbaar bereik | Koeling |
|---|---|---|---|
| CCD & linear array | Leg een golflengteband vast in één opname | Visible/NIR to 2.2 µm | TE cooling |
| Single point | Scan de golflengte met een monochromator | 200 nm to 22 µm | Room temperature, TE or LN₂ |
| PMT | Maximale gevoeligheid voor zeer zwakke UV–VIS-signalen | 185–900 nm, tube dependent | Room temperature |
Spectral coverage and cooling are model-dependent. Confirm the complete optical and electrical configuration before ordering.
De detectorselectie hangt af van het brandvlak, golflengtegebied, signaalniveau en de opnamemethode. Wij kunnen de volledige bron–monster–spectrograaf–detectorketen beoordelen.
