Field of view dependent on Achromatic lens?
« on: November 09, 2017, 01:26:57 PM »
Hi Daniel,
how does the field of view depend on the Achromat used?
We noticed that it changes size, depending on the focal length.

Cheers,
Ivo

Hi Ivo,
The focal length of the achromatic lens changes the overall magnification of the Miniscope system. There is a decrease of about 30% of FOV area when going between a 12.5mm focal length lens and a 20mm focal length lens. The longer the focal length, the smaller the FOV will be. You can use a resolution calibration test slide to get exact numbers.
