6.2 Spectroscopy Applications
This section provides step-by-step instructions for acquiring a spectrum in LightField
for the first time. The intent of this procedure is to help gain basic familiarity with the
operation of the system and to show that it is functioning properly. Once basic
familiarity has been established, then operation with other operating configurations,
ones with more complex timing modes, can be performed.
This procedure assumes:
• The system has been set up in accordance with the instructions in previous
chapters;
• Familiarity with LightField;
If this is not the case, refer to the online help while performing this procedure.
• The system is being operated in spectroscopy mode with a spectrograph (e.g., a
Teledyne Acton Research IsoPlane spectrograph,) on which it has been properly
installed.
• A suitable light source (e.g., mercury pen-ray lamp) has been mounted in front
of the entrance slit of the spectrograph.
Any light source with line output can be used. Standard fluorescent overhead
lamps have good calibration lines as well. If there are no line sources available, it
is possible to use a broadband source for the alignment. If this is the case, use a
wavelength setting of 0.0 nm for alignment purposes.
CAUTION!
!
Overexposure Protection: Cameras that are exposed to
room light or other continuous light sources will quickly
become saturated. If the camera is mounted to a
spectrograph, close the entrance slit of the spectrograph to
reduce the incident light.
• The customer has installed a compatible shutter driver, such as the SHC-EXT
from Princeton Instruments.
• The spectrograph has an entrance slit shutter that is being controlled by the
NIRvana HS via the Shutter connector.
Perform the following procedure to configure LightField for the first time:
1. Set the spectrograph entrance slit width to minimum (10

m if possible).
2. Turn on the spectrograph.
3. Mount a light source such as a Teledyne Princeton Instruments IntelliCal
®
Hg/Ne-Ar Dual Switchable light source in front of the entrance slit.
4. Connect the Shutter connector on rear of the NIRvana HS to the shutter driver.
5. Connect the shutter driver to the entrance slit shutter which may be:
• An External Slit Shutter
A shutter assembly mounted externally to the spectrograph has shutter cable
that plugs into the Shutter driver.
• An Internal Slit Shutter
A shutter mounted internally has an external shutter connector in the sidewall
of the spectrograph.
6. Mount the camera to the spectrograph exit port.
7. Turn on the NIRvana HS.
8. Turn on the host computer.
9. Launch LightField.
