The purpose of the illuminator is to provide even, high intensity light at the place of the field aperture, so that light can travel through the condensor to the specimen.
What is the function of the illuminator on a microscope?
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.
What are the illuminating parts of the microscope and their functions?
Illuminating parts are a mirror and a condenser lens. The light beams from different sources are reflected back by the mirror into the condenser lens, which focuses the light onto the specimen. There is an iris diaphragm which regulates the illumination of the field of view.
What is the function of the mirror?
A mirror reflects light waves to the observer, preserving the wave’s curvature and divergence, to form an image when focused through the lens of the eye.
What is the function of each part of the microscope?
Arm: The arm connects the body tube to the base of the microscope. Coarse adjustment: Brings the specimen into general focus. Fine adjustment: Fine tunes the focus and increases the detail of the specimen. Nosepiece: A rotating turret that houses the objective lenses.
What is the function of a mirror or illuminator in a microscope?
Illuminator: A steady light source (110 volts in the US) that shines up through the slide. Mirrors are sometimes used in lieu of a built-in light. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage.
Which part of the microscope is the most important?
The most important part of a microscope are the objective lenses.
What are the three components of the illuminating system?
To fulfill these requirements, the illumination system of the compound microscope consists of three parts: an internal light source, a condenser, and an iris diaphragm.
How do we hold the microscope properly?
Important general rules: Always carry the microscope with 2 hands—place one hand on the microscope arm and the other hand under the microscope base. Do not touch the objective lenses (i.e. the tips of the objectives). Keep the objectives in the scan position and keep the stage low when adding or removing slides.
What is the function of the body tube on a microscope?
The microscope body tube separates the objective and the eyepiece and assures continuous alignment of the optics. It is a standardized length, anthropometrically related to the distance between the height of a bench or tabletop (on which the microscope stands) and the position of the seated observer’s…
What are 3 types of mirrors?
Three common types of mirror are the plane mirror, which has a flat, or plane, surface; the convex mirror; and the concave mirror.
Why can’t vampires look in mirrors?
Why You Can’t See Vampires In Mirrors. … Vampires are transparent and light passes through them so if they stand in front of a mirror there is no reflection because the light is just passing through them. Vampires can counter this, but for the most part, their reflections are obscured.
Why are mirrors expensive?
Some mirrors are made from cheap material such as plate glass or BK7 while good quality mirrors use expensive material like borosilicate glass or Ultra-low Expansion Glass materials which makes them a lot more costly than a regular/standard mirror.

What are the powers of a microscope?
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers. When coupled with a 10x (most common) eyepiece lens, total magnification is 40x (4x times 10x), 100x , 400x and 1000x.
