Hello. I will continue the story of my experiments to deceive reality
Last week I completed the optical tube, and together with our technologist, we adjusted the diamond inserts on the face mill. I must say right away that the result of the work of the mill turned out to be good. In my experience, the accuracy of the inserts in the face mill is within two microns. In my experience, the accuracy of the inserts in the face mill is within two microns.
But, as you can see from the photo below, the picture quality is far from ideal. The edge of the plate is not clear.
Our rechargeable flashlight, which has always been used to expose inserts, turned out to be disastrously weak for this optical system. As a result, I had to use the flashlight in my smartphone, which, it seems, can send an SOS signal if I find myself on a desert island.
What I plan to do in the future:
- buy a powerful source of directional light and fix it so that the light beam is directed exactly at the center of the lens
- add a green or blue light filter to the light source
- I need to try to shine on the insert from the other side. Now the light hits the back surfaces of the insert, and it seems to me that the light can "go to the sides" and because of this the edge is not so sharp. Perhaps, if you shine on the front surface of the insert, which is strictly perpendicular to the light beam, the result will be better.
- I need to try to work in reflected light, and not in transmitted light, as it is now. It is possible to apply a combination of reflected and transmitted light.
