All modules are permanently wavelength calibrated. Can be saved to the Front End Electronics via the AdminTool software. tec5 uses the C' coefficient set given on the Zeiss protocol.
- Make sure the whole SMA input of a module is illuminated. Zeiss spectrometers' optical input often include a fiber-optical cross-section converter. If only a few fibers are illuminated, wavelength inaccuracies may occur.
- If the input NA is reduced, artifacts originating from the second-order blocking filter may occur.
- If the NA is too small, it affects the wavelength resolution as only a small part of the grating is illuminated. A high-resolving spectrum requires that a sufficient number of grating lines must be illuminated to create a good interference pattern.
- Keep cable length as short as possible
- Apply shielding if applicable
- USB cables - limited to 5 meters
- PCIe cables - Longest tested 8 meters
- Ethernet Cables - limitless
- Very important for a proper video signal
- Combine all GND cables to a central location, such as a metall chassis (if possible)
- Ground shielding cables on one side only
- MMS Modules: Use metal tongue of housing for improved shielding
- Shortest integration time is the readout time (exceptions: InGasAs Arrays and the CGS Spectrometer Module)
- Shortest integration time for the InGaAs arrays is 0.1 ms
- Shortest integration time for CGS Spectrometer module (S1115x Arrays) is 0.25 ms
- Longest integration time is 6.5 s (standard)
- Longest integration time can be extended to up to about 9 min. Please see SDK manuals for details
All detectors show a non-linear response to illumination levels. This can be corrected via software as the response is generally a stable feature of the sensor. Our MultiSpec® Pro II software contains the ability to correct this issue. Please contact us if you are interested in correcting the non-linearity.
Make sure that heat is adequately dissipated from a cooled sensor and provide good airflow and heat conductivity. The maximum temperature that can be bridged is less than 50°C.
