Sensor Size Comparison and Field of View (F.O.V)


Sensor Sizes ▼  Compatible Adapter▼ Filed of View and Range of Photo ▼

Image sensors (CCD, CMOS etc) used in digital cameras vary in sizes depending on maker and
its model. Please refer to below charts describing relation between microscope Filed of View
and shooting range of photo and select correct adapter for your particular DSLR model.

How to find F.O.V
for Olympus Eyepiece
【GSWH10X/22
 
GSWH : model name
10X : magnificaition

22 : F.O.V (φ22mm)
1 Shooting Image is based on the area visible with a 10x eyepiece
2 Make sure F.O.V of you particular eyepiece model
It varies even when magnifications is same
3 Common F.O.V range for high magnification microscope is 18-22
Common F.O.V range for is 22-27
Peripheral image of objective is distorted and out of focus compare to
the center area. Our adapter is optically designed to have shooting range within the FOV and able to capture quality images even to peripheral.

 Formula:

DSLR Microscope Adapter - Field of View (F.O.V) for APS-C, APS-H, 35mm Full Frame, FourThird

 
Calculation Example
Camera : Canon EOS Rebel T3i
Sensor Size : 22.3 x 14.9mm (approx 1.06inch)
LCD Monitor size : 3.0 in (wide)
Adapter : NY-1S (x 1.74)
Objective Lens : x 20
LCD Displayed
Magnification
: 20 x 1.74 x (3/1.06)
 = x98.5 (approximate value)
