The Correct Kind of Overhead Projector (courtesy of Golan Levin)

The Overhead Projector (OHP) must be a traditional analog electric transparency projector. This projector must have a large hollow body in which the table top is also a glass (Fresnel) lens. A good example is the 3M 1820, 3M 1850, or 3M 1880. These projectors look like this:

There are many different manufacturers and models for overhead projectors. It is OK to use an older OHP (from the 1960’s or 1970s) if it is clean and working well. The most important properties of the OHP we need are:

- Transmissive (not reflective)
- We prefer “Doublet” lens
- About 2000-3000 Lumens of brightness
- 10.5-11 inch stage

So, I recommend an Overhead Projector in the 3M series, like the 3M 1880, hopefully with a brightness of 2000 to 4000 Lumens. If you cannot get 3M, there are other brands that work, but please check with us first. It is important that the projector is of the correct kind, as I have already emphasized. You will also need to get a spare lamp (lightbulb) for the OHP! This is especially important for long-term exhibitions (more than a few days).
