3. LongPass Absorbing Filter (optional): If selected, an absorbing filter
is installed between the slit and the aperture in the SMA 905 bulkhead.
The filter is used to limit bandwidth of light entering spectrometer or to
balance color. Filters are installed permanently. A filter is for a specific slit.
If you anticipate needing the filter with multiple slit sizes, then you must
specify this at the time you order. You will know which filter is installed in each slit
because of the color-coded dots on the outside as shown in the figure and described in
the table below.

4. Collimating Mirror (specify Standard or SAG+): The collimating mirror is matched
to the 0.22 numerical aperture of our standard optical fibers. Light reflects from this
mirror, as a collimated beam, toward the grating. You can opt to install a standard
mirror or a NIR-enhancing but UV absorbing SAG+ mirror.
SAG+ mirrors are often specified for
fluorescence. These mirrors absorb nearly all UV
light, which reduces the effects of excitation scattering in fluorescence measurements.
Unlike typical silver-coated mirrors, the SAG+ mirrors won’t oxidize. They have excellent
reflectivity — more than 95% across the VIS-NIR.
Specify standard or SAG+ mirrors when ordering your spectrometer.
