surface. Since the prism surface is narrow,
twist the end of the cotton swab into a
pointed tip and use it to wipe the prism
surface lightly.
2. Wipe the side-view light diffuser plate
and prism using a cotton swab. Use a
hand mirror when wiping the prism
surface since it cannot be seen from the
front.
