rmpsrpms Pillar of the Community United States 4037 Posts	Posted 12/03/2014 10:42 pm What sort of magnification are you looking for? Microscopes have fixed optical systems and adjust focus by moving the subject up or down, or sometimes moving the whole optical path up or down. Some folks have modified their microscopes to have the focus wheel driven by a stepper motor, with the stepper motor controlled by software. Others use a linear stage like a StackShot and mount the subject on it, with software controlling the stage position and thus focus.

I want to have clear focus of a mint mark which fills the screen. I currently have a cheap scope - thought I would try that first. It's software has a focus function but it is grayed out and not active. I did not know about the fixed optical system...I'll try moving the subject - thanks. Report this Post to the Staff

DVCollector Bedrock of the Community United States 10045 Posts	Posted 12/06/2014 8:52 pm Are you looking for finer focus adjustment? I bought myself a used medical lab scope. They will have coarse/fine focus wheels. Then I dropped in this Celeston microscope imager into one of the objective tubes (mine is stereo). That lets me view the image on a big screen and focus mechanically. Report this Post to the Staff

I have an old postal scale from the 50s and decided to try that. It helped! Moving the arm of the scale with one hand makes the adjustment and holds it steady easily. Here is my most recent attempt: https://goccf.com/t/192092#192092 Lighting is still a challenge.. Edited by Pete2226 12/07/2014 06:27 am Report this Post to the Staff
