Mitutoyo 176 808A Toolmakers Microscope
Digimatic Micrometer Heads, 30X Magnification
The Mitutoyo 176 808A Toolmakers Microscope is
one in a series of microscopes that have been specifically designed for the
purposes of measuring the dimensions and angles of a variety of machines/tools.
As such, it can be effectively used for such purposes of checking shapes of
screw threads, inspection of matching templates and gears among others.
Mitutoyo 176 808A Features and Functions
The following are some of the features of the
Mitutoyo 176 808A Toolmakers Microscope:
- A monocular viewing head
- Two digimatic micrometer
- Tungsten illumination
- A 6 x 6 inch stage
- A 15x eyepiece (with built
in vernier protractor- secondary scale)
*Vernier protractor indicates where a given
measurement lies when it is between two marks of the main scale
Unlike a good number of other toolmakers
microscopes in the market where readings have to be done manually, this compound toolmakers microscope comes with two digimatic micrometer
heads with 0.00005"/0.001 mm
resolution display LCD readout, which provides statistical process control
output, allowing for readings to be read directly during measurements. This
makes it easier to get the readings given that they are simply displayed on the
LCD readout than getting the readings on a scale with other tool maker's
In addition to the 2x objectives, this
microscope also comes with 15x eyepiece, which features a built in vernier
protractor as well as a angle dial for controlling angle movement. This
enhances the viewing experience, allowing for more accurate readings.
With regards to lighting, the Mitutoyo
176-808A compound toolmakers microscope uses 24V Tungsten bulbs, which
supports the simultaneous use of contour illumination (method used for
observing a work piece using transmitted light) with green filter for viewing
as well as oblique surface illumination (reflected) with angle orientation
Here, both the transmitted ad reflected illumination
intensity can be adjusted to obtain the optimal illumination
intensity for the work piece.
* Here, it is important to note that the
transmitted light used for this microscope is not meant to pass through the work
piece as is the case with various biological microscopes.
The Mitutoyo 176-808A compound toolmakers
microscope also comes with a diopter adjustment. This is an important component
of the microscope that is often used to compensate for differences in eye
visions. Here, it also serves to show specific magnification power depending on
the person operating it.
The dimensions of the XY stage are 6 x 6 inch,
which is sufficient working space for a majority of the tools measured using
this microscope. Moreover, the stage travel range is 2x2 inch, which is
important for maneuverability, moving the object during observation. This is an
important feature of the tool maker's microscope in that it allows for
effective measurement of the parts of the object.
Some of the other components of the microscope
- A grounding wire
- A bulb setter
- A cross- line reticle
- Len cap
Mitutoyo 176-808A Toolmaker's Microscope with Digimatic Micrometer Heads, 30X Magnification
The Mitutoyo 176-808A Toolmakers Microscope only
achieves a 30X total magnification. This may be one of limitations of the tool
maker's microscope for some users considering that some of these microscopes
can achieve a total magnification of up to 160x. However, this is still good
resolution that will allow for effective measurements of various parts.
The Mitutoyo 176-808A Toolmakers Microscope is a good quality microscope that has been designed with a range of features that allow for comfort during use, enhancing the viewing experience. A good example of these features include the 30-degree depression angle meant to allow for comfortable viewing, an adjustable diopter that accommodates differences in eye vision as well as a leaf spring mechanism, which assist with glass removal and replacement.
This toolmakers microscope therefore serves a great purpose in the measurement of dimensions and angle of machined metals.
