Q
How is the multiple calculated?
Answer Question
A
Equipped with eyepieces: H6mm, H20mm
The multiples are: 300/6=50 times, 300/20=15 times.
If you choose a 3 times Ballov lens, the magnification is 50X3=150 times, 15X3=45 times; plus a 1.5 times orthographic lens, the imaging is a positive image, and the magnifications are: 50X1.5=75 times, 15X1. 5=22.5 times. Namely: minimum magnification: 15 times, maximum magnification: 150 times.
