1 SMA Connector
Secures the input fiber to the spectrometer. Light from the input fiber enters the
optical bench through this connector.
2
Interchangeable
Slit
A dark piece of material containing a rectangular aperture, which is mounted
directly behind the SMA Connector. The size of the aperture regulates the
amount of light that enters the optical bench and controls spectral resolution.
You can also use the NIRQuest without a slit. In this configuration, the diameter
of the fiber connected to the NIRQuest determines the size of the entrance
aperture.
The user can change the slit. Ocean Optics also offers a range of FC connector
slits in the same wavelengths, with the product code INTFC-XXX. An INTFC-KIT
is also available.
3 Filter
Restricts optical radiation to pre-determined wavelength regions. Light passes
through the Filter before entering the optical bench. Both bandpass and longpass
filters are available to restrict radiation to certain wavelength regions.
Only Ocean Optics technicians can change the Filter.
4
Collimating
Mirror
Focuses light entering the optical bench towards the Grating of the spectrometer.
Light enters the spectrometer, passes through the SMA Connector, Slit, and
Filter, and then reflects off the Collimating Mirror onto the Grating.
5 Grating
Diffracts light from the Collimating Mirror and directs the diffracted light onto the
Focusing Mirror. Gratings are available in different groove densities, allowing you
to specify wavelength coverage and resolution in the spectrometer.
Only Ocean Optics technicians can change the Grating.
6 Focusing Mirror
Receives light reflected from the Grating and focuses the light onto the CCD
Detector or L2 Detector Collection Lens (depending on the spectrometer
configuration).
7 InGaAs Detector
Each pixel on the detector responds to the wavelength of light that strikes it.
Electronics bring the complete spectrum to the software.
