QE65000 Components Table
Ocean Optics permanently secures all components in the QE65000 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 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 QE65000 without a Slit. In this configuration, the diameter of
the fiber connected to the QE65000 determines the size of the entrance aperture.
Only Ocean Optics technicians can change the Slit.
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
L2 Detector
Collection
Lens
An optional component that attaches to the CCD Detector. It focuses light from a tall
slit onto the shorter CCD Detector elements.
The L2 Detector Collection Lens should be used with large diameter slits or in
applications with low light levels. It also improves efficiency by reducing the effects
of stray light.
Only Ocean Optics technicians can add or remove the L2 Detection Collection Lens.
8
CCD
Detector
(UV or VIS)
Collects the light received from the Focusing Mirror or L2 Detector Collection Lens
and converts the optical signal to a digital signal.
Each pixel on the CCD Detector responds to the wavelength of light that strikes it,
creating a digital response. The spectrometer then transmits the digital signal to the
OOIBase32 application.
