Overhead projectors

OHPs overhead projectors

Overhead projectors, used in schools, colleges and university classrooms, allow teachers to write ideas down as discussed, which are projected instantly onto a projector screen so that all students can see. OHP's shine light through transparent acetate sheets to display whatever is written or printed on them onto a projector screen. You can also photocopy pages from books onto acetate sheets.

Main advantage of an overhead projector (OHP) over a multimedia projector is cost. Models range from sturdy, budget economy models for prolonged classroom use to stylish, flatbed models for classroom, training and boardroom presentations. Portable flatbed OHP's are available for presentations on the go. Models on the market also include powerful OHPs for large audience lecture theatres. Some models have single lamps, whilst others offer twin lamps, which means that should a bulb go in the middle of a presentation, then with a flip of a switch it transfers to the second lamp and your presentation is uninterrupted. More information on lamps and lenses below.

OHP accessories
Overhead projectorsSingle and triple lenses

Standard single element lens overhead projectors are fine for writing on acetate sheets or displaying text on screen. High definition overhead projectors have a triple element lens that is designed for displaying fine pictures or engineering diagrams. These are more slightly more expensive than standard overhead projectors.

Single and twin lamp projectors

Overhead projector lamps are inexpensive but only last around 50 hours. When a lamp blows it will need replacing. You need to let the projector cool down before doing this. If the lamp dies during a presentation or teaching session this would be inconvenient and disruptive. Twin lamp overhead projectors have two lamps installed with only one lamp being used at a time. If one lamp dies then a switch is thrown to turn on the second lamp.

Projector brightness

Projector brightness is measured in ANSI lumens. Standard overhead projectors are around 2200 ANSI lumens (250 watt) and are fine for normal classrooms. High brightness projectors are around 4200 ANSI lumens (400 watt) and are used in lecture theatres and other very large rooms.

Flatbed and portable projectors

Flatbed overhead projectors are designed to be portable so that the projector can easily be carried between venues. These are around 5kg to 7kg in weight and fold for easy transport. Some standard projectors just have a foldable arm to allow easier transport.
