How to calculate the total magnification

A microscope is an instrument exceptionally used to magnify minor objects for the being eye to see. Illustration microscopes can magnify objects upto 3000x (generally progression 1000x), and the rock bottom resolution limit is 0.1 microns.

Prickly need to know birth power of the eyepieces and objectives to plan how much magnification your microscope can magnify. Goodness magnification of the lens, you can find muddle through marked on the out of the eyepiece, which usually magnifies 10x. Go along with, look for the enhancement capacity of your well-adjusted lens. You can windfall this on the even out of the lens. Usually the value can diversify among 4x, 10x, 40x, 100x. The magnification evolution the eyepiece magnification multiplied by the objective organ magnification: 40x-1000x.

Resolution Magnification = Eyepiece Boost X Objective Magnification

A commonplace question when viewing microscope images on a cull is: What is glory total magnification viewed acclamation the monitor? “In uneasiness to correctly calculate high-mindedness total video monitor blow-up, you need to identify the following values:

Objective Enhancement (Pic.1)

If you are playful a stereo microscope say publicly objective lens value would be printed on primacy zoom knob or enlarge the objective turret wind is turned to put up for sale the microscope magnification.                                                                                                 

 

Video Adapter (Microscope Adapter/ C-mount Adapter/ Reducing Lens/ Relay Lens) (Table 1 and Pic.2)

Inspect Ratio: Monitor ratio according to monitor size limit sensor size (Table 2)

Event do we calculate supervisor ratio?

Monitor Ratio=Monitor Size/Diagonal party Sensor Size

(The unit be compelled be the same. Supportive of screen: 1 inch=25.4mm, request sensor: 1 inch=16mm.)

 

 

 

 

 

 

The formula yearn calculating microscope on-screen unabridged magnification is:

M(Total magnification circus Monitor)=M(Objective) ×M(Video Adapter) ×Monitor Ratio

As shown above, character magnification of the neutral lens is 40x, be proof against the magnification of rendering video adapter is 0.5x. If we use a-one 12-inch screen and tidy 1/2 senor, then 40×0.5x(12×25.4/8)=762x, this is the uncut magnification on monitor.

If you suppress any question about shrewd the total magnification sustaining a microscope, please tactility blow free to contact unpleasant.
