Choosing a microscope is simply a question
of getting the right tool for the job. Since microscopes are put
to such a wide range of uses, there are naturally many types of
microscopes and specialized accessories. This is a brief guide to
the types of microscopes that Meiji Techno offers and the applications
for which they are commonly used.
| Biological
Microscopes |
These microscopes are used by
laboratories, universities and hospitals to look at biological
specimens for research and diagnostics. |
| Industrial
Microscopes |
Industrial Microscopes
are used primarily in assembly work or quality control. They
are used to inspect materials and finished products. |
| Stereoscopic
Microscopes |
Stereo microscopes are typically
used in work or study environments that require users to work
with the specimen with their hands or with tools under the microscope.
Usually low magnification however, some models can achieve 300X
with decent resolution. |
| Electronic
Inspection Equipment |
Usually stereo
microscopes are used to inspect printed circuit boards for flaws
in manufacturing or production. An "oblique viewer"
can be added on a stereo microscope giving it the capability
to revolve around a component to inspect its connection to the
PCB. |
| Measuring
Microscopes |
These are microscopes with digital
readouts on the stage lead screws. They provide reliable, accurate
and repeatable measurements on x, y and z axis. |
| Metallurgical
Microscopes |
Metallurgical
microscopes are used throughout the sciences and industry. They
are made to observe shiny and/or flat metal or other surfaces. |
| Polarizing
Microscopes |
Polarized Light Microscopes have
many applications in the science, industrial and academic fields.
Using polarized light, scientists can discover the origin, content
and chemical makeup of many different organic and inorganic
materials. |
| Asbestos
Microscopes |
Meiji Techno
has specialized asbestos microscope models for mineral and other
fibre discovery and identification for abatement companies and
government agency's worldwide. |
| Video
Macroscopes |
Video Macroscopes are used in
machine vision, measurement and production environments where
small size and high resolution are required. |
 |
 |
 |
| 10X Magnification |
35X Magnification |
70X Magnification |

Applications
Your
application is the most important factor in deciding which
microscope to use. What you need to see and what you want
to do with that image will determine what kind of microscope
you need. There are two basic types of optical microscopes:
compound and stereo. If you need very high magnification
to view the internal structures of cells, you would most
likely use a compound microscope. If you need to examine
solder joints on circuit boards or other relatively large
objects, you would probably use a stereo microscope.
Within
each of these applications, however, there can be far more
demanding requirements; a researcher studying the functions
of neurons will require a far more sophisticated instrument
than a high school biology teacher introducing students
to cellular structures for the first time. If you have a
very specific application, you may need a highly specialized
microscope or special accessories. With our wide range of
microscopes and accessories, Meiji Techno can help you configure
an instrument for almost any application.

| Compound
Microscopes
Compound
microscopes like the one pictured here are what most people
visualize when they think about microscopes. They have a
number of objectives (the lens closest to the object being
viewed) of varying magnifications mounted in a rotating
nosepiece. Typically the range of magnification on a compound
microscope is between 40x and 1000x, although some are capable
of higher or lower magnifications.
Because
only one objective is used at a time, the viewer sees a
two-dimensional image of the specimen (usually reversed
and upside-down).
Although
there is no product listing on the Meiji Techno homepage
menu for "compound microscopes," the listings
for biological,
metallurgical
and polarizing
microscopes all refer to types of compound microscopes.

| Stereo
Microscopes
Unlike
a compound microscope that offers a 2-dimensional image,
stereo microscopes give the viewer an erect (upright and
un-reversed) stereoscopic (3-dimensional) image. This is
particularly useful for biologists performing dissections,
technicians repairing circuit boards, paleontologists cleaning
and examining fossils, or anyone who needs to work with
their hands on small objects.
Most
stereo microscopes are used at magnifications from 5x to
50x, but with the proper microscope and accessories, magnifications
up to approaching 400x can be achieved. Meiji Techno offers
two basic types of stereo microscopes: the EM
Series based on the Greenough design, and the RZ
Series based on the common-main-objective design.

Photography and Video Applications
For
many applications the ability to capture, display, and preserve
specimen images is of equal or greater importance than actually
viewing the specimen through the eyepieces. Photomicrography
(35mm and other chemical formats) has been a common option
on microscopes for decades, but the recent development of
relatively inexpensive CCD (charged couple device) video
and digital cameras has greatly increased both the popularity
and flexibility of microscope imaging. Instead of clicking
through slides during a lecture, university professors can
now display real-time video images on projection televisions;
petroleum geologists can e-mail images of core samples to
their laboratories from remote locations around the world;
oncologists can refer to CD or on-line catalogues of cell
images to help them make faster and more accurate diagnoses.
Whether your application calls for 35mm, large-format Polaroid,
video, or digital imaging, Meiji Techno can provide you
with the appropriate microscope and accessories.
Trinocular
Microscopes
There
are many different methods for capturing, displaying, and
recording microscope images, and each has its own advantages
and disadvantages. It would be impossible to cover all of
these options here (Check the Photo/Video
Accessories page for more details), but one basic piece
of information will be important in selecting your microscope:
While it is possible to mount a camera on a monocular or
binocular microscope
(Note: a binocular microscope has two eyepieces,
but is not necessarily a stereo microscope), it is far better
to use a trinocular microscope designed for camera work.
Trinocular
models have two eyepieces for normal viewing, plus a third
"phototube" on which you can mount a camera without
interfering with the normal operation of the microscope.
Nearly all of the Meiji Techno microscopes you will find
on this website are available in trinocular models.
Hopefully
this brief outline can help you to determine which kind
of microscope your application requires.
