Spectroscopy Systems
For our CCD- linescan cameras some standard spectrographs with different gratings are available (other systems on demand).
In principle the cameras can work with all kinds of spectrographs, but it should be considered, that the spectra should be focused on a straight line. The focal line of a standard monochromator is a curve. Resultingly a measured spectra will be defocused in the sensor surface plane. The offered spectrographs have a special flat field correction for usage with linear sensors. We offer complete systems with the camera mount included. Also cooled systems for reduced dark noise are available. |

Sensors
For low cost applications the camera with the sony sensor ILX511 suits for the spectrometers very well or for high data rates the Dalsa sensor IL-C6.
Anyway the best choice for spectroscopy applications are the Hamamatsu PDA's (Photo Diode Arrays) when long exposuretimes are needed or FFT's (CCD-arrays, FFT: Full Frame Transfer) with especially large pixel sizes and increased sensitivity for low light applications. |

FFT and PDA sensors |
Example - spectra of a cold light lamp |
|
| |
| The FFT's are more sensitive than the PDA's, but don't have build in shutter and antiblooming function. They can also be delivered as back side illuminated thinned versions (series S7030 and S7031) with enhanced quantum efficiency especially in the UV spectral region. |
