Lytro Photography through Microscope
on: 2014/05/31 00:27

Hi,

I was able to take photos with the Lytro through a microscope. Without the eyepiece, I was not able to take any photos with the microscope - the pictures were just a small bright circle.

Taking photos through a 10x objective yields photos, and I can touch to refocus on the screen. However, the Lytro photos after processing have vertical or horizontal dark lines as defects. These lines throws off the refocusing - instead of refocusing on the subject, it is refocusing on the dark grid.

I think I understand why the artifact is there. The Lytro camera operates using a f/2 lens, which only operates at f/2. The microlens are designed to accept f/2. However, through the 10x microscope eyepiece, I am not getting large angle rays - ie, it is smaller than f/2. Looking at the raw pictures through Lytro Compatible Viewer shows that the photos are composed of small dots surrounded by black - indicating that it is not getting large angle rays from the eyepiece. This is the cause of the dark grid.

I think using a higher magnification objective may help, as it produces larger angle rays.

Do you think this is correct? Let me know your thoughts.

Thanks,
James

I don't know the answer to your question but read on the Lytro webpage the following quote. "In terms of our camera working with a microscope, the image-side f-number is highly mismatched between cameras and microscopes" I don't understand this statement or the implications of it but seems to agree with your statement. I was wondering if you considered using a inverted zoom lens as a microscope primary. The image may have more of the large angle rays.
