TRANSMITTED LIGHT OBSERVATION
}When an SZX series transmitted illumination base is used, the microscope can be used in transmitted light brightfield/
darkfield, focal light and simplified transmitted polarized light observations.
To perform these observations, rotate the mirror unit turret on the coaxial fluorescence illuminator to select the light path
without fluorescence mirror unit (No. 4/TBF).
The following table shows the main specifications of the transmitted illumination base.

Note 1. When the MVPLAPO2XC objective is used and the zoom ratio is 2.5X or less, insufficiency of brightness in the
peripheral section becomes noticeable. To prevent this, place the diffusion plate* ( 45 mm, made of plastic)
provided with the microscope body below the stage glass of the SZX transmitted illumination base.
When the SZX-ILLB2 is used and the contrast selector lever is set to the "High" position, irregularities may be
noticeable in the image.
* A protection sheet is attached to the diffusion plate. Peel off the sheet before using the plate.
Note 2. To reduce background noise during fluorescence observation, it is recommended to use the SP-BW-2 stage
plate (B&W) or the SP-FL fluorescence center plate (with metallic plate).
However, if transmitted light observation is also necessary, use the SP-C stage glass or the SP-FL fluorescence
center plate (with glass plate) instead, and place the ND6 filter (
position for the diffusion plate described in Note 1) above. If both the diffusion plate and ND6 filter are used, they
can be stacked in the position.
