Re: Camera sensor size to see bigger F.O.V.
Yes you're right, edge's sharpness is also important for stitching. I am thinking that i can crop the best clear area from the bigger images (from the vignetted) maybe this work but I am not sure without try the camera I think Xline Olympus objective is good for this kind of situation ( but very exp...

Re: Camera sensor size to see bigger F.O.V.
Mu purpose is seeing bigger field of view. For example when scanning 15mmx15mm area, I have to take 650 photos (0.75mm x 0.55 mm). If I see bigger area for example (like 0.85mm x 0.75mm) I need less image and as a result less time to scan a tissue

Re: Camera sensor size to see bigger F.O.V.
@Hobbyst46 actually it is a scanner, objectives's FN value is 26.5 Tube lens information: Focal length : 180mm Projection area: 26.5mm, Focal Plane Position: 151.3mm 0.74mm obtained from 40x 0.95NA objective. When I checked image diameter through the eyepieces, (Olympus CX23 microscope) diameter is ...

Re: Camera sensor size to see bigger F.O.V.
First of all thank you for fast reply
Our equipment consist of ;
40x UPlanApo 0.95NA objective is purchased from Chinese
0.35X C-mount Camera adaptor and 1X Tube lens (both of them are from Olympus)
Actually the image on the tube lens is bigger than 0.75 x 0.55 mm, but camera has limited f.o.v.

Thank you @Scarodactyl I will also consider your shared product. So just to clarify something, How much bigger area can I see with best optical system at 40x ? For example https://www.leicabiosystems.com/digital-pathology/scan/aperio-gt-450/ (please navigate to COMPARE section)in this site there are...

Re: Increase FOV
Hi again, I have played some configuration within our optic system. I just put tube lens reversed and see that magnification decreased and field of view increased but image was not good as before. (I just wondered that how this will affect the situation) Field of view increased about 0.1 mm after tu...

So I will try with 0.5x tube lens and i will investigate the how 0.5x tube lens affect magnification and field of view
Thank you again

Re: Increase FOV
Hi, sorry for the late reply. Yes you're right tube lens is important factor. "How did you determine that the objectives do not magnify 40X in a CX 23?" As I understand from the images taken with my phone camera, same objects has different pixel length. Actually I tested with 20x objectives that fie...

Re: Increase FOV
Yes @apochronaut i agree with you 40X Olympus UPLFLN objective is magnifying more than the 40X Olympus Plan objective. Yes 40x UPlanApo 0.95NA objective is purchased from Chinese and it is not Olympus. I also viewed with microscope(Olympus CX23) and I see that 40x 0.65 is not magnify 40x or others i...
