We offer one of the largest selections of microscopes, digital microscopes, and digital cameras for microscope eyepieces. We also carry a large variety and antique accessories, and other microscope parts.
Compound Microscopes
A compound microscope uses multiple lenses, namely the objective lens and the eyepiece (ocular) lens, to magnify static 2D samples. These lenses allow the compound microscope user to observe a large amount of detail in the samples. They are typically simple to use, feature their light source, and are convenient to set up. Our compound microscopes for sale are also lightweight, making them easy to store.
What is a Compound Microscope Used For?
Most of us remember using a microscope at some point in school, usually in biology class (or a science class that included a section on biology), and for most of us, it was the same kind of microscope. A " biological microscope " is one kind of compound microscope. Sometimes other names are used for biological microscopes too. If you hear either of the terms "brightfield microscope" or "transmitted light microscope," it is referring to the same thing.
There are other types of compound microscopes in common use too. A phase contrast microscope uses a special lens, called a "phase contrast objective lens," together with a phase slider (or phase turret condenser). This combination intensifies the contrast of the object being observed, without the need to stain it with dye. These "phase contrast" microscopes are often used in university and medical research settings, to look at bacteria, blood cells, and other tiny structures in living creatures. We’ll go into them in more detail below.
Another type of compound microscope is the " polarizing microscope ." These use an analyzer and a polarizer to cross-polarize and pick out even subtle differences in colours in the optical path of whatever it is being examined. These microscopes are especially useful in science and industries that examine chemicals. Pharmaceutical companies, petrologists and geologists often use polarizing microscopes for the examination of chemicals, minerals, and thin slices of rock samples.
Finally, fluorescence microscopes and differential interference contrast microscopes (DICs) are other types of a compound microscopes. They are both used most commonly in biology-related fields and use different light wavelengths to fluoresce an object under observation, highlighting particular features of the sample.
Stereo Microscopes
A stereo microscope is an optical microscope that provides a three-dimensional view of a specimen. It is also known by other names such as dissecting microscope and stereo zoom microscope. Dissecting microscope parts include separate objective lenses and eyepieces. As a result, you have two separate optical paths for each eye. The slightly different angling views to the left and right eyes produce a three-dimensional visual. Because it gives a three-dimensional view it is also called as the dissecting microscope.
The Characteristics of a Stereo Microscope
Two separate objectives
Two separate optical paths
Uses the light reflected from the object
Typical magnification range between 10x and 50x
Three-dimensional images
Parts of a Stereo Microscope
Stereo Head: This is the moveable top portion of the microscope and the stereo head holds the two adjustable eyepieces.
Ocular Lens: These are the eyepieces through which the viewer looks at the specimen. The eyepieces are typically set at 10x magnification. It is also possible to upgrade to a higher magnification level.
Diopter Setting: It compensates for the focusing differences between the left and right eye. Setting it correctly prevents eye strain.
Objective Lens: Stereo microscopes have two separate objectives, each one connecting to one of the eyepieces. The eyepiece and the objective lenses collectively determine the magnification of the microscope. They can have a fixed single objective, a rotating multiple-lens turret or a zoom. It allows you to change the magnification levels depending on the applications.
Focus Knob: Stereo microscopes usually have one focus knob. Helps move the head of the microscope up and down to bring a sharp image of the object. Most dissecting microscopes have standard "rack and pinion" focusing. Rack is the track with teeth and pinion is the gear that rides on the teeth. The knob helps the pinion move along the rack.
Stage Clips: Stage clips help to hold the slides or other thin objects in place on the stage.
Stage Plate: It is located directly under the objective lens. It is where the specimen is placed for viewing. Some stereo microscopes have reversible black and white stage plates to provide appropriate contrast with the object being viewed.
Illumination: Many microscopes have both top and bottom lighting. Some microscopes only have one source of illumination, top or bottom. The top lighting shines down on the specimen and reflects light off them. The bottom lighting transmits light up through the stage to show translucent specimens.

While you need to purchase your growing researcher their own magnifying instrument for examine done outside of the school lab, you don't have the foggiest idea what highlights are fundamental and what highlights are only there to make the magnifying instrument sound more great than it really is.One beneficial thing to know is that the nature of an understudy magnifying instrument doesn't constantly connect with its sticker price, and on the off chance that you realize what to search for, you can get a very OK understudy magnifying instrument at a similarly better than average cost.While picking an understudy magnifying lens from numerous sensibly valued alternatives, you simply need to guarantee that the magnifying instrument you are thinking about have some crucial characteristics that will make them ideal for any scholastic endeavor.Attractive Features Of A microscopes for studentsThe main element you should search for in an understudy magnifying instrument is its center ability.
A decent magnifying instrument will have both fine and coarse center settings; both are basic if your understudy is to utilize the magnifying instrument for a wide range of survey.The whole explanation behind purchasing an understudy magnifying lens is, obviously, to let your understudy amplify protests so their surfaces can be contemplated in detail.
You ought not make due with a magnifying instrument with under 400X amplification, and 1000X would be greatly improved.
Be that as it may, the more noteworthy the amplification, the darker the outside of the article will show up.
So your selection of magnifying lens will likewise need to incorporate a light source fit for enlightening even the most profoundly amplified examples.
Both fluorescent and halogen bulbs can do the activity.The "organize" of the understudy magnifying instrument, on which the examples will be set for review, ought to work precisely with the goal that your understudy won't need to turn away from the magnifying lens' eyepiece while modifying it.
