Before purchasing or using an overhead projector, it is a good idea to become familiar with the following components and options.

Lenses
Overhead projector lenses come in three different variations: singlet, doublet, and triplet. The image projected will get sharper as your lens quality increases (singlet is the most basic triplet is the most advanced).

Brightness
A projector´s brightness is measured in lumens. There is a wide range of lumens available. Lower lumen models work best with black and white images. When using color, choose an overhead projector with high lumens so the color is vivid and bright.

Head Types
Closed: Lenses and mirror are enclosed to keep out dust and fingerprints.
Open: Lenses and mirror are not enclosed.
Inverted: This is an open-head version. An inverted head lowers the projector height so it is easier to view the screen.

Features
Lamp changer: For uninterrupted use if lamp burns out during presentation.
Color tuning: For image color adjustment in a wide range of projection.
Lamp High/Low switch for brightness vs. Longer lamp life.
Folding Post for storage and portability.
