Episcopic Illuminator

The illuminators which can be used for this microscope system include a coaxial episcopic illuminator, which is attached
between the zooming body and tube, a ring fiber illuminator, which is attached to the tip of the objective, and an illuminator
that has a flexible fiber for adjusting the illumination direction.

P2-CIA Coaxial Epi Illuminator

7.1
Attach this illuminator to the position between the zooming body
and the tube. The C-FLED2 LED Light Source for Fiber
Illuminator is used as its light source. The light from the light
source is led into the device by the two-branch fiber and episcopic
illumination is generated along the optical axis. This illuminator is
suitable for observing mirror-like samples.
 1/4 λ plate
When using coaxial epi illuminator with a 0.5x or 1x objective,
an optional 1/4 λ plate must be attached to the tip of the
objective.
1/4 λ plates are supplied to prevent flare in the imaging
system due to light reflected into the optical system.
There are the following two types of 1/4 λ plates.
• P2-CIA QL0.5X 1/4 λ plate 0.5x for coaxial epi illuminator:
Intended for 0.5x objectives
• P2-CIA QL1X 1/4 λ plate 1x for coaxial epi illuminator:
Intended for 1x objectives
When using a 0.5x objective, remove the protection ring from
the tip of the objective, and then screw the 1/4 λ plate. When
using a 1x objective, remove the correction glass from the tip
of the objective, and then screw the 1/4 λ plate.
The brightest illumination is generated when the white dot on
the 1/4 λ plate is at the front. Select a position that has the
optimum brightness and contrast for observation.
