INTSMA Slit
Installation Instructions
Description
Ocean Optics Jaz, Torus and QE65 Pro Spectrometers offer a special feature that make them even
more customizable for your unique application. Part of the versatility of these spectrometers lies in
their replaceable laser-cut slit and aperture assemblies (INTSMA). Your spectrometer arrived with the
slit size specified in your order. However, if your needs have changed, you can order additional
replacement slits (in various widths from 5 µm to 200 µm) and install the new slit using these
instructions. Be sure to use a fiber with a diameter that matches the slit size to optimize throughput.
The INTSMA slit kits offer you the following advantages:
• Adjustable Throughput
The spectrometer throughput can be set for applications such as absorbance and fluorescence.
For example, QE65 Pro users who need great sensitivity for low light applications can change
slits to avoid saturation in absorbance applications.
• Adjustable Optical Resolution
Optical resolution is a function of grating groove density and slit size. By changing slit size,
you can observe different Raman shift resolution with a single QE65Pro spectrometer.
• Multiple Uses for Your Spectrometer
For example, a Jaz spectrometer can be changed from an absorbance spectrophotometer in the
lab to a fluorescence unit in the field. Or a Torus configured to resolve closely aligned
emission peaks for one application and make low light level measurements for another.
• Field-Changeable
Our laser-cut slit and aperture assemblies can be changed in the field, eliminating the need to
send us your spectrometer for rework. Changing slits can be as easy as removing a few
screws. You can also send us your spectrometer to change the slit size and take advantage of
the opportunity to purchase one of our calibration and maintenance packages.
Note
If you are changing to a smaller slit size, you will need to have your spectrometer
recalibrated for accurate measurements. Best practice would be to validate the
spectrometer calibration using an HG-1 Mercury Argon Calibration Source (or similar
light source) whenever the slit size is altered.
