■ Focus adjustment mechanism:
With TOOL SCOPE, a focused image of sample can be obtained when the sample and the front edge of objective lens reach a specified distance (working distance).Because the main unit of TOOL SCOPE does not have any mechanism to bring an object in focus, a focus adjustment mechanism to match both distances of the sample and the front edge of objective lens with each other is required separately.
Note, however, that a working distance is determined by an objective lens used. The higher the magnifying power of the objective lens, the shorter the working distance becomes.
Various supporters are made available which function to hold TOOL SCOPE in place and additionally have the focus adjustment mechanism.
■ Illumination:
Illumination is required when observing a sample. Excluding those products with built-in lighting equipment, lighting needs to be provided from an external source. Also, when the illumination from the built-in lighting equipment is not sufficiently bright, external lighting is required.
As such external lighting, lighting of light-guide type, oblique lighting, ring lighting, etc. are available.
To keep the lighting equipment itself which is a heat source away from a sample, use the lighting of light-guide type, whereas this lighting of light-guide type should be selected as well when illumination intensity needs to be increased. Because the lighting of light-guide type provides oblique lighting where illumination is given from the surrounding area of objective lens, there are instances in which illumination cannot be provided by a high-magnification objective lens because the sample comes closer to the front edge of lens.

※Working distance: It is the distance between a sample and the front edge of objective lens when creating an image of the sample.
※Actual field of view: It is the range of a sample which can actually be observed. This value is determined by multiplying the number of eye-piece's fields of view (the range of an image of objective lens which can be observed with eye-piece) by the magnifying power of objective lens.
※The overall magnifying power is what can be obtained through multiplication performed for each magnifying power of objective lens and eye-piece to be combined with each other.
※The overall magnifying power is based on the combination of TOOL SCOPEs (mechanical tube length: 163 mm).
