Types
of Microscopes:
Stereo Microscopes are used for inspection
and work usually involving non-microscopic activities, such
as inspection of coins, insects, electrical and machine
components, rocks and gems, etc. They are also used for
dissection. They are often referred to as "low power
microscopes". These Microscopes provide enough magnification
to see and manipulate the fine details of specimens and
objects. Objects are seen in 3-D through dual objectives.
Compound Microscopes are made with education
in mind and generally offer higher magnification than stereo
microscopes. The typical magnifications are of 40x, 100x,
400x, and even 1000x.They are primarily used for viewing
microscopic items, such as cells, cell structures, bacteria,
microscopic creatures, etc. They are often referred to as
"high power microscopes".
High Power Professional and Industrial Microscopes
offer advanced optics and capabilities required in medical
and research professions. These Microscopes offer superior
optics and performance required for demanding applications.
Features generally include binocular heads, trinocular heads
for photography, variable halogen illumination, built-in
mechanical stage, semi-plan, plan, and infinity optics,
dark field, phase contrast, koehler illumination, and more.
Microscope
Features:
To ensure that you are getting a quality microscope, it
is important to look for the following features in the microscopes
that you are comparing. These features are a testament to
the integrity of the manufacturer with regard to their products
and services.
- State
of the art DIN objectives (now the standard, and are
easier to repair).
- Parfocality,
Parcentrality enables the user to switch optical powers
and keep the specimen still within the field of view with
minimal fine focus adjustment.
- Student-Proof
features like locked-on stage clips, eyepieces, locked-in
or one-piece eyetube, slip clutch focusing system to protect
the gears from over-focusing.
- Adequate
plate on bottom (make sure edges are not sharp and
wires are not exposed).
- UL-Approval
not only guarantees safe operation for the user, but
is a well-reputed quality and the standard for electrical
instruments.
- Smoothness
of rotating head (no grinding, sticking).
- Spring-loaded
40 + 100X objectives (necessary to protect cover glass
and slide from damage).
- All-metal
internal parts are what will guarantee that a microscope
can withstand the wear and tear of constant use.
- Patented
features assure that the manufacturer is willing to
invest in their product designs.
- Warranty
- on defective parts and workmanship for the natural life
of the instrument.
