From time-to-time customers have prepared slides that are a challenge to slide scanners. One such obstacle is slides that are extra-thick (over 1.5mm).
The uScopeMXII slide tray has springs (slide clips) on each side of the tray that hold the slide in place and keep it stationary during scanning. These springs are designed to accommodate a maximum slide thickness of 1.5mm.
Customers can request a uScope to be built with a springless slide tray. However, this places a few responsibilities on the user to ensure quality scans and proper operation of the uScope.
This image shows a standard uScopeMXII slide tray (with the springs installed). Slides are inserted label-last (so that the label is sticking out the front of the uScopeMXII). Several parts of the slide tray are necessary for successful scanning.
Normally, the slide springs hold the label end of the slide down and prevent lateral and longitudinal slide movement while scanning.
With the springs removed, there is nothing to prevent slide movement. Any slide movement results in scans that do not stitch properly and that do not accurately target the desired region of interest.
Our solution is to place a small piece of double-sided tape to the bottom of the slide underneath the inside edge of the label (as shown). A large piece of tape is not required. We have found ½" Scotch (3M) double sided tape works well. It is available at most office supply stores and, of course, Amazon.com.
When you insert a slide into the uScopeMXII, it is important to push the slide in as far as possible. This ensures the far end of the slide is positioned under the slide retainer.
The retainer is angled so that the end of the slide is forced down and does not bounce or lift up while scanning.
The retainer securely holds the far end of the slide down while, in this case, the double-sided tape holds the label end of the slide down. The tape also prevents lateral and longitudinal movement of the slide while scanning.
Inserting a taped slide into a springless slide tray is a little different than inserting a non-taped slide into a standard slide tray.
Perhaps the easiest part of using the uScopeMXII is removing a slide. Simply grab the label end of the slide between your thumb and forefinger and pull straight out. This is the easiest way to break the adhesion between the tape and slide tray. There should be no reason for the slide to catch or stick while removing it.
