Aven Tools is frequently asked if it is possible to set up a stereo zoom microscope to remain in focus throughout it’s magnification range. It is possible through a process called parfocaling, and Tim Nelson will show you how.
Step 1. Zoom the microscope all the way in to it’s max magnification, then adjust the microscope position until there is a clear image.
Step 2. Zoom the microscope all the way out, then adjust the focus of the eyepieces until there is a clear image.
Step 3. Adjust the camera collar until there is a clear image on screen.
Now the microscope will remain in focus through the eyepieces as well as on screen, with no need to adjust the optics. To learn more visit aventools.com, or contact us at firstname.lastname@example.org
