Sensor Size Comparison and Field of View (F.O.V)
About Image Sensor Sizes and Adapter Selection
Image sensors (CCD, CMOS, etc.) used in digital cameras vary in size depending
on the manufacturer and model. Please refer to the chart below showing
the relationship
between the microscope field of view and the camera’s shooting range,
and select the appropriate adapter for your specific 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. |
