QE
Pro
Components Table
Ocean Optics permanently secures all components in the QE
Pro
at the time of manufacture. Only Ocean
Optics technicians can replace interchangeable components, where noted.
Item Name
Description
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 QE
Pro
without a Slit. In this configuration, the diameter
of the fiber connected to the QE
Pro
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
Back-thinned
Area Detector
with TE Cooling
Provides 90% quantum efficiency and bins pixels in a vertical column to
acquire light form the entire height of the spectrometer’s slit image. This
improves light collection and signal-to-noise significantly. This 2D area detector
is back-thinned (back-illuminated) and does not require the detector upgrade
that is normally applied to other detectors.
Only Ocean Optics technicians can add or remove the Detector.
8
Detector
with OFLV Filter
Eliminates second-order effects and is used with an HC-1 Grating in a 200-950
nm wavelength system in a QE
Pro
.
