Microscope Magnification and Field of View Calculator Details
Are you a biology student or researcher looking to analyze microscopic samples with precision? Our Microscope Magnification and Field of View Calculator is here to help! This powerful tool allows you to determine the field of view of your microscope based on the objective lens magnification and eyepiece field number, making your observations more accurate and informative.
How to Use the Calculator
Using the calculator is straightforward. Simply input the field number of your eyepiece and the magnification of your objective lens, and the calculator will provide you with the corresponding field of view diameter. This information is crucial for understanding the size and scale of the objects you're observing under the microscope.
What are Microscope Magnification and Field of View?
A microscope's magnification is the ratio of the size of an image to the size of the object being viewed, and it's determined by the combined power of its objective lens and eyepiece. The field of view, on the other hand, is the diameter of the area visible through the eyepiece or camera.
Calculating Magnification and Field of View
Our calculator offers three methods for determining magnification and field of view:
Calculate the Field of View Diameter
Input the eyepiece field number (FN), objective lens magnification (MO), and tube lens magnification factor (MT) to find the field of view diameter.
Calculate the Diameter for a Higher Power
Enter the magnification of the lower power objective lens (MLP), the lower power field of view diameter (DLP), and the magnification of the higher power objective lens (MHP) to determine the field of view diameter for a higher power objective.
Calculate Estimated Specimen Size
Provide the microscope field of view diameter (DFV) and the number of specimens in the field of view (N) to estimate the size of the observed specimen.
Common Questions and Example Calculation
What if I don't know the eyepiece field number?
Most eyepieces have the field number engraved on them, but if yours doesn't, you can use a standard value of 18-22 mm.
How do I determine the tube lens magnification factor?
The microscope manufacturer usually provides this value, which can range from 1x to 1.6x, with 1x being the most common.
Microscope Magnification and Field of View Calculator Example
For example, Let’s say you have the following data:
- Eyepiece Field Number (FN): 20 mm
- Objective Lens Magnification (MO): 40x
- Tube Lens Magnification Factor (MT): 1.0x
- Low Power Magnification (M LP): 10x
- Low Power Field of View Diameter (D LP): 2 mm
- Higher Power Magnification (M HP): 100x
- Number of Specimens in the Field of View (N): 5
Calculate Field of View Diameter:
DFV = 20 mm / 40×1.0 = 0.5mm
Calculate the Diameter for a Higher Power:
DHP = 10 × 2 / 100 = 0.2mm
Calculate Estimated Specimen Size:
Lsp = 0.5 / 5 = 0.1mm
