P-Dsf32 Fiber Diascopic Illumination Stand - Nikon SMZ25 Instruction Manual

P-DSF32 Fiber Diascopic Illumination Stand

8.4
The P-DSF32 is a stand equipped with diascopic illumination
optical systems and the focusing mechanism of the support pillar
vertical movement type.
Combine this stand with an SMZ18 via a P2-FMDN Focus Mount.
This stand cannot be used in combination with an SMZ25.
The base with a large glass plate (180 mm dia.) enhances
usability and enables easier observation of samples in a container
such as a petri dish.
A dedicated hex driver is located at the top of the support pillar.
Sliding mechanism of the stage plate
The sliding parts are mounted on the base part for
mounting the stage plate, which can be slid by loosening
the stage plate fixing screw. There is a clearance gap of
approximately 3 mm around the stage plate when the stage
is securely set. The stage plate can be smoothly and finely
moved within the clearance gap by loosening the stage
plate fixing screw.
This mechanism is useful for positioning, especially for
high-magnification observation.
Securely fix the stage plate in place using the fixing screw
when this mechanism does not need to be used.
 Illumination of/off, brightness adjustment
Attach the C-FLED2 LED Light source for fiber illuminator as
the light source to the rear side of the base using a fiber. Turn
the illumination on/off and adjust the brightness using the
C-FLED2. For details, refer to the instruction manual supplied
with the light source.
 OCC (oblique coherent contrast) illumination
This stand supports OCC illumination so that a transparent sample can be observed at high contrast using diascopic
illumination with a white LED. OCC illumination is an oblique illumination method suitable for observing the phase objects,
where a sample is obliquely illuminated with a coherent illuminating light by shielding a part of the optical path using a
shading plate. With this illumination method, a colorless, transparent sample can be observed with relief and contrast.
To adjust the OCC contrast, turn the OCC adjustment knob. Adjust until the optimum observation state is obtained in
combination with the selected magnification and phase amount of the sample. In addition, the control position (knob
position) can be reproduced using the adjustment knob with a scale.
 Condenser lens
The base contains condenser lenses for low/high-magnification microscopy. Switch the condenser lens based on the
objective being used to ensure uniform diascopic illumination. A wide range of observation magnifications are supported.
To switch the condenser lens, slide the condenser lens switching lever to the right or left.
