Fly & LED ring

Post by Adalbert »

Hello everyone,
I have just tested my LED ring.

BTW, the photograph has been taken by Olympus MSPlan 50x / 0.55 and CANON EF 70-200L

Interesting. Was there some lag between photos? The second stack makes me suspect the eye may have dried a bit. I like the first photo a bit better because the lenses are shiny.

Can you share how the ring light was positioned? What was the objective's working distance? The clarity at that mag is impressive! Your technique is excellent!

Hello Keith,
I am very glad that you like it.
- No, there were only some minutes between the stacking sessions.
- The WD of this Olympus is 8.1mm.
- The ring was mounted directly on the microscope lens. So, the lens was in the middle of the ring.
BR, Adi

Impressive detail. I'm not sure how this is working though. The ring light you link to is for the front of a stereomicroscope and has quite a wide diameter fixing, but from the magnification and resolution, it looks as though your images are taken with a microscope objective, which would have a much smaller diameter. Have you made some kind of adaption collar for the objective?

Hello Cactusdave,
Yes, I have changed the screws (to 5 cm long)

and used the mount of my medical diffuser.

Thanks for the info and the link to the diffuser setup.

The results are quite good and at very high magnification. The close coupling between actuator and bug provides good stability. Very important with LED exposures.

If the working distance is just 13mm and the leds are pointing straight ahead, surely hardly any light reaches the subject ?

First, the pictures demonstrate that light is illuminating well
Second, the LEDs are pointing inwards, clearly shown at the last picture, sadly the diffuser if used is not pictured

Hello Pau,
The diffuser for this LED-ring has been made of paper:
