These are particularly useful for determining the diameter of a microscope field. One of the larger divisions is positioned at one edge of the field of view, so that the fine part of the scale ovelaps the opposite side. The field diameter can then be determined to the maximum available precision.... A formula would be nice to have since the diameter or distance of the wedge area can change and the degree of the field of view can also change. Thank you and I look forward to hearing from you. Frank. Hi Frank, The area of a circle is π r 2 square units where r is the radius in units and π is approximately 3.1416. Thus for a radius of 6 miles the area of the circle is π × 6 2 = 36 × π

**Diameter of Field of View YouTube**

The field of view is the area seen through the magnifier. As power increases, lens diameter and field of view decrease. At 5 power (5X), field of view is about 1.5". At 10 power (10X), it is about 0.5". Usually, it is best to use low power for scanning larger surfaces and high power for small areas.... 9/09/2014 · Calculate the diameter of the field of view under different magnifications.

These are particularly useful for determining the diameter of a microscope field. One of the larger divisions is positioned at one edge of the field of view, so that the fine part of the scale ovelaps the opposite side. The field diameter can then be determined to the maximum available precision.... You cannot measure the diameter of the high-power field of view using the procedure outlined above because it is less than one millimeter, but you can use the! following ratio to calculate the field diameter under high power.

**Microscope Lab Estimating Size and Calculating Magnification.**

Field of View (FOV) The field of view is the maximum area visible through the lenses of a microscope, and it is represented by a diameter. To determine the diameter of your field of view, place a transparent metric ruler under the low power (LP) objective of a microscope.... b) If the diameter of the low power field is 2 mm, what is the diameter of the high power field of view in mm ?.8 mm The ratio of low to high power is 20/50. So at high power you will see 2/5 of the low power field of view (2 mm). 2/5 x 2 = 4/5 = .8 mm

## How To Find The Diameter Field Of View

### You cannot measure the diameter of the high-power field of view using the procedure outlined above because it is less than one millimeter, but you can use the! following ratio to calculate the field diameter under high power.

- The true field of view is therefore 1.25-degrees (50/40=1.25). The other formula for calculating FOV in degrees involves dividing the eyepiece field stop diameter by the prime focal length of the telescope and multiplying the result by the constant of 57.3.
- To calculate the diameter of the field of view for low and medium power. 1. Copy the following 2 tables into your notes under the “Observations” section of your lab report.
- The field of view is the area of sky or land seen through your binoculars, determined by the design of the instrument’s optics. It is expressed in two ways; as the width in feet at 1,000 yards, or in degrees of field. When expressed in feet the field is called linear, and when expressed in degrees it is called angular. Don’t let the terms confuse you, the conversion is easy – divide the
- Help us to grow by adding additional equipment to the database. When adding an eyepiece or binocular, please don't include the magnification or aperture details in the model, this will get added automatically.
