|
|
| What are the major types of optical microscopes? |  |
| The most common types of microscopes are classified according to the type of view they provide. A high-power or compound microscope gives a highly magnified view of a tiny cell, mineral grain or pixel on a c |
|
|
| How does a microscope work? | |
| A microscope works by producing an enlarged image of a small object. Because the eye can only focus to about 10 inches (25cm), this limits its ability to see fine detail by simply moving in close |
|
|
| How does a microscope get light to the specimen? What do I need to know about illuminators? | |
| The lowest-powered microscopes may not need any light other than that provided from room lighting or the sky. However, the microscope may be so close to the specimen that the instrument may shade it. Or you |
|
|
| What is a condenser? | |
| A condenser is a glass lens or lens system located within or below the stage (sub-stage) on compound microscopes. Its basic function is to gather the light coming in from the illuminator and to concentrate t |
|
|
| Magnification: how do I calculate it for my microscope? | |
| It’s very easy to figure out the magnification of your microscope. Simply multiply the magnification of the eyepiece by the magnification of the objective lens. |
|
|
| What’s the resolution of a microscope? Is this related to numerical aperture? | |
| A microscope’s resolution is its ability to form separate images of lines or dots. It’s defined in terms of the actual distance between details on the object. The wave nature of light puts a prac |
|
|
| What do the numbers on the barrel of the microscope objective mean? What about the letters DIN and JIS? | |
| Microscope objective lenses will often have 4 numbers engraved on the barrel in a 2x2 array. The upper left number is the magnif |
|
|
| How do I focus my microscope? | |
| First, insert a slide or you specimen on the microscope stage. For first time use, get an object with a clearly identifiable pattern, like the engraving marks |
|
|
| What are parfocal objectives? | |
| Parfocal refers to the ability to change objectives with differing powers and have the focus remain sharp. The distance from the top of the objective to the object being viewed is the parfocal distance. |
|
|
| My microscope has a filter wheel. How is it used? | |
| Filters are used to increase contrast and color correction for visual observations of specimens or slides. They may be used with live specimens as a non-lethal substitute for staining. |
|
|
| My 100x objective is called a wet objective. What does this mean? What is oil immersion and why is it important? | |
| A wet objective means it operates with oil between the lens and the specimen. Oil concentrates light from the condenser and reduces light losses from reflection and refraction. Oil immersion is the technique |
|
|
| What is the difference between achromatic, semi-plan and plan objectives? | |
| Most microscope objectives come in three basic designs: achromatic, semi-plan and plan.An achromatic objective corrects for color and has a flat field across the central 65% of the image. It&rsqu |
|
|
| What is the working distance of my microscope? | |
| There are two working distances for microscopes: objective and stage. Together they define the space you have to work with objects and still focus with your microscope. |
|
|
| How do I use my microscope for photography? | |
| There are several ways your microscope can take photos.The first method is to use a |
|
|
| What do I need to know about microscope stages? | |
| Your microscope’s stage holds specimens and slides for examination. Plain stages are usually fixed platforms with a circul |

|
| What’s the best microscope for looking at coins, stamps, jewelry and rocks? | |
| A stereo microscope is the best choice for looking at collectibles. Its lowest powers may allow you to see the entire stamp or coin. It has enoug |
|
|
| What is the standard diameter of microscope eyepieces? | |
| The international standard microscope eyepiece tube diameter is 23mm or about 0.9 inch.Many stereo microscopes use eyepieces with a barrel diameter of 30mm (1.2"). |
|
|
| What would be the best microscope for surveying a Petri dish’s contents? | |
| A stereo microscope would be effective for examining Petri dishes. The stage is large enough to hold big dishes and the wide field of view will make it easy t |
|
|
| What is bright-field illumination? How is it different from dark-field illumination? | |
| In order to see specimens clearly, a microscope will need to light or illuminate them. The most common type of illumination for biological micros |
|
|
| What is the resolution of my microscope in microns and image scale in microns per pixel? | |
| A microscope’s resolution is its ability to form separate images of lines or dots. It’s defined in terms of the actual distance b |
|
|
| I’m a stamp and coin collector. Which microscope is best for getting pictures of a whole stamp or coin? | |
| You want a microscope that has a very low power.Since most coins and stamps are approximately an inch i |
