It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially, a compound microscope consists of structural and optical components. However, within these two basic systems, there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated and explained below.Structural Components:
- The three basic, structural components of a compound microscope are the head, base and arm.
- Head/Body houses the optical parts in the upper part of the microscope
- Base of the microscope supports the microscope and houses the illuminator
- Arm connects to the base and supports the microscope head. It is also used to carry the microscope.
- There are two optical systems in a compound microscope: Eyepiece Lenses and Objective Lenses:
- Eyepiece or Ocular is what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10 x. Optional eyepieces of varying powers are available, typically from 5x-30 x.
- Eyepiece Tube holds the eyepieces in place above the objective lens. Binocular microscope heads typically incorporate a diopter adjustment ring that allows for the possible inconsistencies of our eyesight in one or both eyes. The monocular (single eye usage) microscope does not need a diopter. Binocular microscopes also swivel (Interpupillary Adjustment) to allow for different distances between the eyes of different individuals.
- Objective Lenses are the primary optical lenses on a microscope. They range from 4x-100x and typically, include, three, four or five on lens on most microscopes. Objectives can be forward or rear-facing.
- Nosepiece houses the objectives. The objectives are exposed and are mounted on a rotating turret so that different objectives can be conveniently selected. Standard objectives include 4x, 10x, 40x, although different power objectives are available.
- Coarse and Fine Focus knobs are used to focus the microscope. Increasingly, they are coaxial knobs - that is to say they are built on the same axis with the fine focus knob on the outside. Coaxial focus knobs are more convenient since the viewer does not have to grope for a different knob.
- Stage is where the specimen to be viewed is placed. A mechanical stage is used when working at higher magnifications where delicate movements of the specimen slide are required.
- Stage Clips are used when there is no mechanical stage. The viewer is required to move the slide manually to view different sections of the specimen.
- Illuminator is the light source for a microscope, typically located in the base of the microscope. Most light microscopes use low voltage, halogen bulbs with continuous variable lighting control located within the base.
- Condenser is used to collect and focus the light from the illuminator on to the specimen. It is located under the stage often in conjunction with an iris diaphragm.
- Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage. Most high quality microscopes include an Abbe condenser with an iris diaphragm.

We service and repair all sorts of microscopes.
We have spares for all kinds of microscopes and we can offer all variety of support for microscopes.
- Eyepiece: Microscope eyepieces (especially in biological microscopes) are typically 10x magnification. The eyepiece might have the ability to insert a reticle into it for making measurements. Some high school microscopes come equipped with a pointer in one of the eyepieces - this makes it easier for the teacher to point out specimens to students.
- Siedentopf Head: A siedentopf binocular head differs from a sliding binocular head in that the eyepieces can be adjusted in a circular movement up and down, rather than simply sliding closer together or further apart. The Siedentopf head adjusts the interpupillary distance by turning (rotating) the eyetubes about a central axis (that also has the distance scale printed on it). This system is designed to change the interpupillary distance without changing the tube length, so it is "compensation-free." In other words, you do not need to compensate for tube length changes manually. The sliding binocular head, is called "Jentsch," where the interpupillary distance is changed by moving the eyetubes closer together or farther apart in a linear fashion. In this design, the tube length changes when changing interpupillary distance, so the user has to compensate for that by adjusting the "focus" setting of the eyepieces on a scale to correspond to the interpupillary distance used. Siedentopf is particularly helpful when multiple users are using the same microscope.
- Carrying Handle: The best way to carry the microscope is to pick it up by the carrying handle and transport it while supporting the base.
- Coarse Focus: The microscope coarse focus knob will move the stage (in some cases it will move the head of the microscope) to change the focus. Coarse focus moves in a larger increment than fine focus would and should be the first knob used to adjust specimen focus.
- Fine Focus: Once the coarse focusing knob has been adjusted to get the specimen mostly into focus, the fine focus knob does exactly what the name describes - finely focuses the image.
- Rheostat Light Intensity Control: This knob is adjusted in order to make the light brighter or dimmer.
- Illuminator: The illuminator in this particular microscope is an LED light, which is a bright, cool light. Other lights you might find in a microscope include halogen (it heats up!), fluorescent (cool), or tungsten (also heats up). LED and halogen are usually the most common lights found in microscopes. LED light bulbs last much longer than halogen bulbs.
- Condenser: The microscope condenser is a lens that concentrates light from the illuminator and focuses this light through the specimen and into the objective lens.
- Mechanical Stage: A mechanical stage allows control of the slide without using your fingers - it consists of a slide holder and two knobs. The knobs allow for movement in the X or Y axis.
- Slide Holder: The slide holder is part of the microscope stage that holds the microscope slide securely in place.
- Objective Lens: The microscope objective lens gathers light from the object being observed and focuses the light rays to produce an image. The objective lens is also part of the overall magnification - the total magnification comes from a combination of the objective lens power and the eyepiece power.
- Revolving Nosepiece: The revolving nosepiece holds the objective lenses in place and allows the user to switch from one magnification to another without removing the objective lens.
