I´m just trying to find the correct backfocus for our new 6200.
The drawing says 17.5mm with the tip tilt plate, without it that should be 12.5mm
The ccd window is 2mm, and I assume the IMX455 has a 1mm coverslip, that would make about 1mm difference optical.
Long story short, is the specified backfocus optical or mechanical?
Thanks in advance
