Applications

Overhead projectors like the 3M 1865 were the standard presentation tool in classrooms, corporate training rooms, and conference rooms from the 1970s through the early 2000s, before LCD projectors became mainstream. Instructors and presenters would place printed or hand-written transparency sheets on the illuminated glass stage, and the lens arm would project the image onto a screen or white wall. The 3M 1800 series was one of the most widely used OHP lines in North American education and business settings. While newer digital projectors have largely replaced OHPs in most environments, these units remain in use in schools and organizations that still maintain transparency-based training materials, and they are also sought by collectors and vintage AV enthusiasts. The portable, fold-flat form factor of the 1865 was designed specifically for presenters who needed to move the unit between rooms or carry it to off-site venues.
