Operating the illumination
The P-400R has a ring illuminator consisting of eight white LEDs around the objective.
Caution: Notes on the ring illuminator
Note the following when using the illuminator:
Do not point the luminous section to a person.
Do not look into or look directly the luminous section.
When you observe a specimen with a high reflection rate, illumination may be
scattered around the specimen. Wear protective glasses or goggles if
necessary.
About the illumination when observing a sample with a polished surface
When observing an object having a high reflection ratio, such as a sample with a
polished surface, under low magnification, if you use the ring illuminator in
P-400R, an LED image may be reflected. In such a case, use another illuminator.
