When measuring something with a meniscus, you should always measure at the lowest point of the curve. For no particular reason other than scientists have accepted that has the standard.

Field of view microscope definition in simple terms it is the area you see under the microscope for a particular magnification. Say, for example, you are viewing a cell or specimen under an optical microscope. The diameter of the circle that you see is the field of view of the microscope.

If using a stereo microscope with an auxiliary lens, the magnification factor of this lens should also be employed in the equation by multiplication with the objective magnification. You will have to multiply the eyepiece magnification by the objective magnification to find the total magnification before dividing the field number.

When you switch eyepieces or objective lenses, ensure to repeat the FOV calculations with the new inputs on field number and magnifications. For objects that require higher magnifications, convert your measurements from millimeters to micrometers.

Higher power lenses will allow you to view tiny objects, so the angle of view will be small; low power lenses will do the opposite and let you view bigger (wider) objects.

IDS Imaging uEye+ GigE Cameras are used in a variety of applications such as automation, automotive, medical technology, and logistics.

The Gain camera feature allows you to increase the brightness of the images output by the camera. Increasing the gain increases all pixel values of the images.

You would zero your balance to maintain accuracy in your measurements, in other words, to get the correct weight. A balance works much like a see-saw. If you have two people of equal weights on opposite sides, the see-saw balances, but if one of them sits closer to the center than the other, they APPEAR to have different weights.

A meniscus is the curvature that is seen when water is poured into a relatively narrow glass cylinder, for example a graduated cylinder. This is caused by the water having a greater attraction for the sides of the cylinder than for itself. Because of this, it appears to “crawl” up the sides of the tube.

1) a compound microscope involves 2 lenses (the ocular that you look through, and the objective down by the slide). The magnification of these is multiplied to get the total magnification. For example, if the ocular has a magnification of 10x, and the objective has a magnification of 10x, the total magnification would be 100x. Also, the microscopes will allow you at most to see the organelles within cells. You CANNOT see atoms with any of the microscopes you listed.

As you increase the magnification, the field of vision is reduced. Depending upon the lens system, this can vary. A crude way of measuring the field of view is by using a ruler under the microscope for a particular magnification.

When you record the image to a digital medium the FOV can be expressed as a distance (e.g., 1 mm) or in calibrated pixel counts (e.g., 1024 pixels at 1 um/pixel) along the major axis.

To calculate the field of view of microscope you need to know the eyepiece magnification, field number and objective lens. Once you have this information you can calculate the field of view of the microscope by dividing the field number by the magnification number.

The Field of View on a microscope determines the size of the imaged area. It gains importance when you want to measure specifics such as densities -for example, an experiment to estimate the density of cells in a solution. To get the answer, you have to acquire an image of a Field of View, count the number of cells and divide it by the imaged area. The result would be an estimate of cells/micron.

Note that the extent of the Field of Vision depends on the magnification. Objectives with higher magnifications have smaller Fields of Vision. Thus, the size of the Field of Vision should be selected as a function of the size of the features that are to be studied. Bacteria are smaller (around 5 microns) than most human cells (a brain's astrocyte can have 90 microns in diameter). Therefore, to study astrocytes larger Fields of Vision are necessary.

Best Answer: The difference is a simple microscope has one lens where a compound microscope has an objective lens and an eyepiece with a longer focal length. a simple microscope only has one type of lens, usually objective lens, but a compound microscope had both objective lens and ocular lens.you should zero your balance because since a menicus can not be read properly. one usually has to estimate the amount by reading it at eye level. To actually know the correct amount thats in your pipette, you need to set your balance at zero. a simple microscope has one lens (handheld), and a compound microscope has more than one lens (an eyepiece & objectives)A compound microscope will have many different zoom options when choosing what level of magnification. Its magnification also relies on more than one lense (hence the word compound).A simple microscope will magnify much less than a compound one.A magnifying class will do just that magnify the image. Any time you magnify something you lose detail. Compund and even some simple microscopes use a x10 magnification on the eyepiece that will reduce the loss of detail.A meniscus is just the center of something. So If you look at a scale the middle part where the scale teeters is the meniscus. When you weigh something you must make sure the scale is equal to zero. If you do not then your measurement will not be accurate because you may be starting with an incorrect reading.

Field of view (also abbreviated as FOV) for a microscope is the extent of the observable area in distance units. The optics provide a clear and undistorted view in a field around the optical axis, and the field of view is selected from this.  The rays that produce the image in this view are generally aberration-free and do not create a significant falloff in image intensity.

Generally Fresnel lenses are divided into 7 classes (called orders). The order is determined by the distance of the flame to the lens. The First Order ...

For instance, if your eyepiece reads 10X/22, and the magnification of your objective lens is 40. First, multiply 10 and 40 to get 400. Then divide 22 by 400 to get a FOV diameter of 0.055 millimeters.
