Important facts about stereo microscope

Stereo microscopes have 3D viewing of varieties visible to the uncovered eye. They are popularly referred to as Dissecting or Low Power Microscopes. It is estimated that 99% of stereo microscope applications use not as much of 50x modification. It is best to use them for viewing circuit boards, plant life, crystals, insects, etc.
Dual power magnification: The dual power stereo microscopes offer two or above fixed points of magnification at an affordable cost without compromising on optic quality. 20x/40x and 10x/30x are the two common kinds. You need to simply turn the objective lodging to select into the right level of magnification. One of the excellent starter microscopes is the dual power.
Zoom magnification helps you to zoom easily through the magnification range just like SLR camera or the binoculars. Some have click stops or detents at intervals over the zoom range in order to quickly get back to the accurate level of enlargement in the zoom scope.
Focusing: While viewing an opaque or solid object, it is recommended to use the top incident light. You need to utilize the bottom light for better transparent specimens. The majority of stereo microscopic applications need only top light.
Barlow lens: It is possible to use either an accessory or Barlow lens to change the mainlength of the microscope along with the working distance, field of view, and magnification power. For instance, if you are having a 0.5x Barlow lens, you need to adjust to halve the magnification level as you double the working distance.
Stereo microscope parts
There are three main parts in the stereo microscope.
  • Viewing body or head which accommodates the optical constituents in the upper portion of the microscope.
  •   Stand that offers assistance to the microscope and has an integrated illumination.
  •    Focus block attaches the microscope from head to stand and concentrates on the microscope.
It is well known that stereo microscopes are modular. It means it is possible to use the same head in conjunction with various focus stands and blocks.
Just like in the compound microscope,   the stereomicroscope has two optical systems. They are objective lenses and eyepiece lenses.
Oculars or eyepieces help you to view from the top of the microscope. The standard eyepieces come with anexpanding power of 10x. There are optional eyepieces with different powers ranging from 5x to 30x.
Eyepiece tube helps in holding the eyepiece in the right area above the objective lens.
Diopter adjustment ring helps for possible discrepancies of our vision in one or both the eyes.
