Microscopes

Microscopes are used to look at things that are not visible to the naked eye. This category would demonstrate how microscopes work and information about different kinds of microscope.

4,322 Questions

What parts of the microscope are responsible for illuminating?

The light source (such as a bulb or LED), condenser lens, and diaphragm are responsible for illuminating the sample in a microscope. The condenser lens focuses the light from the source onto the sample, while the diaphragm controls the intensity and quality of the light.

What is occhiolino?

"Occhiolino" is an Italian word that translates to "wink" in English. It refers to the action of closing and opening one eye quickly, often used to signal a shared secret or understanding between two individuals.

What is scanning in reading?

Scanning in reading is a technique where you quickly look through a text to find specific information, such as keywords or dates, without reading every word. It is an efficient way to locate details in a text without the need to read it in its entirety. Scanning is often used when you have a specific question or need to find particular information within a text quickly.

The coarse focus knob should be used with what lenses?

The coarse focus knob should be used with low power objective lenses, typically 4x and 10x, to bring the specimen into general focus quickly. This knob makes larger adjustments to the focus position.

What are occulars on microscope?

Oculars, also known as eyepieces, are the lenses through which the viewer looks to observe the magnified image of the specimen on a microscope. They typically provide additional magnification to the image produced by the objective lenses.

What is the small disk found under the stage that regulates the amount of light that reaches the specimen in a microscope?

The small disk found under the stage of a microscope is called the diaphragm. It is used to control the amount of light passing through the specimen, helping to adjust the contrast and brightness of the image being viewed. By adjusting the diaphragm, the user can optimize the visibility of the specimen under different lighting conditions.

How much bigger does a microscope make something appear?

1000x microbes are so tiny they need something to maximemise them alot

What part of the microscope holds the eyepiece?

The body tube of a microscope holds the eyepiece at the top end.

Which lens of a microscope is responsible for producing a magnified image on the inside of the microscope that is not seen directly by the person using the microscope?

The objective lens is responsible for producing a magnified image on the inside of the microscope. This image is then further magnified by the eyepiece lens before it reaches the eyes of the person using the microscope.

Mixtures with different parts that can be plainly seen with the naked eye but speckled under a microscope are called?

Heterogeneous mixtures have different parts that can be plainly seen with the naked eye. When viewed under a microscope, these mixtures appear speckled or uneven due to the uneven distribution of components within the mixture.

What is the greatest use of IR scanning systems?

The greatest use of IR scanning systems is for thermal imaging applications, such as detecting temperature variations, locating heat sources, and identifying energy inefficiencies. These systems are commonly used in areas like medical diagnostics, building inspections, security surveillance, and industrial maintenance.

Who invented the worlds first microscope?

The world's first microscope was invented by Zacharias Janssen and his father Hans in the late 16th century. They were spectacle makers from the Netherlands.

Compare the function of the brightness control with the iris diaphragm?

the brightness control is the control that varies the luminance of the fluorescent screen of a cathode-ray tube, for a given input signal, by changing the grid bias of the tube and hence the beam current.The iris diaphram contains the amount of light that can enter through to the specimen.

What does the microscope use to form images?

Microscopes use lenses to focus light onto the specimen being observed. This magnifies the image, allowing for details to be seen that are not visible to the naked eye. The image formed is then viewed through the eyepiece or camera attached to the microscope.

How is the orientation of the letter e changed by the lenses of the microscope?

The orientation of the letter "e" seen through a microscope will be inverted, meaning it will appear upside down compared to the original orientation. This is due to the way the lenses in the microscope refract and bend light as it passes through them, resulting in a flipped image.

What are the 3 lens sizes on a microscope?

That depends on the type of microscope you are using, so check the lab you work or go to school in. At my lab, our microscopes have 4x, 10x, 40x, 100x magnification lenses.

Why background scanning is done before scanning the sample in ftir?

Background scanning in FTIR is done to capture the interference signals from factors like ambient air or solvents, which can affect the accuracy of the sample signal. It helps determine the baseline noise level and allows for the removal of background signals from the sample spectrum, resulting in a more precise analysis of the sample.

What advantage of electron microscopes compared to light microscopes is that electron microscopes?

have a higher resolution, allowing for the visualization of smaller objects and details. They also have a higher magnification, offering greater detail and clarity in the images produced. Additionally, electron microscopes can resolve structures that are beyond the resolving power of light microscopes.

Why store a microscope on the lowest objective?

Storing a microscope on the lowest objective (usually the 4x lens) helps protect the more delicate and higher magnification objectives from potential damage. The lower magnification objectives are sturdier and less prone to getting damaged if the microscope is accidentally bumped or mishandled. It also ensures that the lenses are in a safe position when not in use.

Why did the stereo microscope get the name stereo microscope?

The root stem of the word 'stereo' is 'stere' which is New Latin and from the Greek meaning solid, or three dimensional.

Because a stereo microscope uses two eyepieces to look down two separate objective lenses, it renders a three dimensional view of the specimen to the viewer.

What part of the microscope supports the objective lens system and the eyepiece?

The body tube of a microscope supports the objective lens system and the eyepiece. This tube holds the optics in place and allows for adjustments to focus on the specimen.

The is what the 3 objective lenses are attached to?

The three objective lenses are typically attached to a rotating nosepiece on a microscope. The nosepiece allows for easy selection of the desired magnification by rotating the lenses into position above the specimen. This configuration enhances the versatility and efficiency of the microscope during observation.

Knob on the end of a sword handle?

The knob on the end of a sword handle is called a pommel. It serves to balance the sword and provide a counterweight to the blade. Pommels can also be used as a striking or bludgeoning weapon in combat.
