Typically, when magnifying and observing cylindrical shapes with small diameters and high reflectivity (such as wires and filaments), glare may occur, making observation difficult.
This time, various methods of illumination were applied under the following conditions for observation.
|
Specimen: φ1mm wire and filament Observation equipment: Microscope Setting: Approximately 50x (field of view: 8×6 mm) |
(1) Observation with the standard LED ring light
 |
|
The standard ring light causes reflection (glare) to occur.

(2) Illumination from a low angle along the longitudinal direction of the specimen

(3) Arch light

■ Advanced application
An alternative method is to use the “4-segment LED light” and “V-block” for observation.
＜4 segment LED ring light＞
Illuminate two diagonal points and shine light from the longitudinal direction of the specimen, as shown in (2).
(This alone may be sufficient to achieve the desired effect)
 |
 |
＜V-block＞
Attach a reflector (in this case, white paper) to the V-block to allow the light to wrap around the specimen.
