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.
