Microscopes

Sara's best choice for filming the movement of chromosomes during cell division would be a fluorescence microscope. This type of microscope can visualize fluorescently labeled chromosomes in real time, allowing for the observation of dynamic changes during cell division.

1.hold the microscope two hands one on the arm/ handle and the one is in the base of the microscope

2. Store the device in a clean dry box or cabinet, usually with some kind of plastic dust cover.

3. When using the High-Power objective lens, be very careful when focusing not to drive the head of the lens into the cover-slip or slide. Always visually adjust the head of the lens about 1 mm or so above the cover-slip, then looking through the eye-piece, use the "fine" focus control to bring the sample into sharp focus.

4. Always replace damaged parts and components with manufacture recommended replacements. If you must use other manufacture's parts, be sure they have the right specifications for your particular microscope.

5. When moving your microscope from place to place in the lab, use one hand to grip the microscope while supporting it at the base with your other hand. This keeps accidents and the lost of parts to a minimum.

6. Don't leave slide, sample, and cover-slip on the microscope stage for extended periods of time, and when through viewing, raise the objective lens away from the cover-slip and turn the objectives to the lowest power objective len setting. Remove the slide and put the microscope away.

7. If the microscope uses a light bulb as its light source, turn the power off when the microscope isn't actually in use.

8. Cleaning the eye-piece and objective lens, aways follow the manufacture's recommendations and instructions.

Generally speaking, the clips on the stage hold the slide down and in place.

A microscope magnifies an object, allowing small details to be seen more clearly. It uses lenses to focus light on the object, enabling observers to view it at a level of detail not possible with the naked eye.

Magnetic lens utilize the Lorentz Force which they deflect the charged particles such as electrons or ions. The lens is round shaped with a core of pure iron, surrounded by copper wire (like a simple electromagnet with magnetic force inside). Usually the core of pure iron include four different layers: two outer ones are north poles and the two inner ones are south poles. When charged particles travel through the hole in the middle of the lens the magnetic force will deflect the beam, focus or widen it depending on the type of lens is convex or concave. Another thing important is that there is an electric current running through the wire to create magnetic force so magnetic lens would be heated very quickly as so they need to be cooled down with water or liquid nitrogen.

Magnetic lens have two main aberration types: chromatic aberration (due to the monochrome of the beam) and the spherical aberration (due to the equal spread of magnetic force over the surface area of the magnet's core).

Recently, they use superconductors to create magnetic lens as well to increase perfection of magnetic lens as superconductors can create strong magnetic force in a small region of the core in which improve the correction of spherical aberration. Beside, superconductors can save more power as the current keep running infinitely as there is no resistance. However, as the current is static, it's hard to maintain the strength of the magnetic force that would lead to harsh of maintenance of lens's focal length (the main factor that create the magnification and resolution of the lenses)

For more complex calculations and equations related to magnetic lens, you can search for it on other webpages.

An electron microscope would be the most suitable to view a virus that is 50 nanometers in size. The resolution of an electron microscope is much higher than a light microscope, allowing for visualization of smaller structures like viruses.

Multiply the magnification of the eyepiece (usually 10x) and the magnification of the objective you are using,

Example: eyepiece = 10 x objective lense = 40x

10 x 40 = 400

magnification of 400x.

Macro-scope

You could probable find them in places like walmart and Kmart and places like that, just go to the stores and ask.

1. Place slide on stage and stabilize w/clips
2. Center slide on stage
3. Lowest-power objective lens is in place
4. Decrease between stage and tip of objective lens
5. Focus with coarse and fine knobs

The total magnification of a microscope is determined by multiplying the magnification of the objective lens by the magnification of the eyepiece. This calculation gives the overall magnification level that is achieved when viewing an object through the microscope.

In order to focus a high powered lens, you have to turn the knob using the scanning lens. Then rotate the high powered lens. But you must be careful as to not turn the knob so much that it cracks the slide because then you have to clean a glassy mess.

You could reuse the microscope to observe something else, store it, or let someone else borrow it, etc.

The basic microscope is an optical instrument that uses a lens or a combination of lenses to produce magnified images of small objects, especially of objects too small to be seen by the unaided eye.

Modern instruments, such as an electron microscope, use electronic or other processes to magnify objects in a similar way.

Microscopes are used in industrial processes, in investigation of living cells, in comparative studies of chemistry and geology, and in diagnostic medicine.

Zaccharias Janssen and his father Hans lippershey in 1959

Scanning is a speed reading technique. An advantage of scanning is that it allows you to quickly cover a large amount of information to find a specific piece of information.

The future for microscopes is likely to involve advancements in imaging technology, such as the development of higher-resolution and higher-speed imaging techniques. Additionally, the integration of artificial intelligence and machine learning algorithms may enable automated analysis of microscopic images, allowing for faster and more accurate data acquisition and analysis. There may also be advancements in portable and handheld microscope devices, making microscopy more accessible and convenient. Overall, the future of microscopes holds great potential for furthering scientific discoveries and applications in various fields.

Don't crush the slide with the objective lens.

we did both agent x's quizzes.

First Quiz: We found out that Montys colours = superb fairy wren.

Agent X always gives us the cluse.

Sadly the 2nd clue was Muray Renmark.

Our teacher said North Para.

ANswer?: Murray Renmark

Lesson?: ALways listen to Agent X.

The code leads to murray renmark river. (Crime Site)

ALways Trust Agent X.

We lost our chance to go to canberra cos our teacher didnt trust him.

AF Smyth is former agant he wants to help.

carry by arm and base

hold the arm by the right hand your left at the base

An optical microscope

put the slide on the platform, start with lowest magnification, gradually adjust the fine adjust knob until image appears clearly. then, keep switching to higher magnification powers.
