Hi,
When running the auto calibration on my microscope, flatfield correction with the 4x lens does not work as expected, a pink circle remains in the corners of the image:
I was able to get rid of the pink shadow playing with the illumination and removing the lens from the condenser. But shouldn’t the software also be able to do that with flatfield correction?
Also I am planning to use the openflexure microscope for a project where I need to use a lens with an even lower magnification. Got these 1x and 2x lenses from Aliexpress with 45mm parfocal distance: https://www.aliexpress.com/item/1005005885257912.html?spm=a2g0o.order_list.order_list_main.23.56cb18021e0qZ6
In theory a lens with these specifications should work, right?
The image with the 2x lens looks like this:
So basically I can get a sharp image with this lens, but most of the image is black. Also the object needs to be very close to the lens, much closer than the 23.5mm working distance that were advertised in the product description. What could be the issue here?
