Typically,

(1) Observations are made using two polarizing filters,
(2) Adjusted to be orthogonal to each other.

This method allows obtaining contrast and coloration based on the sample’s polarization characteristics. It is also effective in reducing sample reflection and glare.

(1) Two polarizing filters are used.
In the case of our company’s metal microscope
(on the light source side)	(on the lens side)
In the case of our company’s microscope (halation removal microscope)
(on the light source side)	(on the lens side)
(2) Adjusted to be orthogonal to each other One of the two polarizing filters can be adjusted for this purpose.
In the case of our company’s metal microscope, (adjusted on the light source side.)
In the case of our company’s microscope (halation removal microscope), (adjusted on the lens side.)
Rotating the polarizing filter gradually induces changes.

(Note) Applying polarization can suppress reflection and glare to some extent. However, it may not completely eliminate them. The effectiveness can vary depending on the object.
