Overhead Projector, Deluxe, ABS Body

Quick Answer: The Overhead Projector, Deluxe, ABS Body is the upper grade of the standard-size overhead projectors in this range, housed in moulded ABS plastic, for projecting transparencies and transparent objects from its lit glass stage onto a screen. A deluxe overhead projector is aimed at rooms where the projector is used every day rather than occasionally.

Where the Deluxe Grade Fits

The range runs from economy through regular to deluxe, and deluxe models are also offered in a bigger ABS body with and without a vari-focal lens. The listing does not spell out the deluxe features. In overhead projectors generally, higher grades are distinguished by points such as a brighter or longer-life lamp, a spare-lamp changeover so a failed lamp is replaced by turning a knob, a better-corrected head lens with less colour fringing, and quieter cooling, so ask which of these apply if a particular feature is required.

For science teachers the benefit of a well-lit stage is in live demonstrations. Transparent dishes placed on the stage turn small reactions into large projected images: universal indicator changing colour as acid is added, crystals of a salt growing as a solution evaporates, or a precipitate forming where two solutions meet. Transparent plotting compasses placed around a current-carrying wire show the field direction to the whole class at once.

For larger rooms, the bigger deluxe ABS model is available, and the economy ABS model shares the same housing material at an entry grade.

Specifications

Care & Handling

• Do not rest hot apparatus or burners on the stage; the glass and the Fresnel lens beneath can crack or warp.
• Use shallow, stable dishes for liquids and wipe up any spill immediately with the lamp off.
• Replace the lamp only with the type specified for the projector; a wrong lamp may overheat the ABS housing.
• Cover the projector when not in use to keep dust off the head mirror.

Demonstrations and Teaching

• Daily transparency teaching in mathematics, physics and chemistry classrooms.
• Projecting microscale reactions in shallow dishes so the whole class sees colour changes.
• Showing field patterns with transparent plotting compasses around a wire or magnet.
• Presenting prepared transparencies in training rooms and lecture rooms.

Why Choose LabEquip

Deluxe overhead projectors are chosen by departments that still teach heavily from transparencies and by colleges that use them for live demonstrations. LabEquip lists this model in the General Lab Products range; send questions about lamps and features through the contact page.

Frequently Asked Questions

What does deluxe mean for an overhead projector?

It marks the upper grade of the range. The listing does not detail the features, but in overhead projectors higher grades usually offer points such as a brighter lamp, a spare-lamp changeover or a better lens, so request the feature list before choosing.

What is a spare-lamp changeover?

Some projectors hold two lamps. If the working lamp fails during a lesson, a lever or knob moves the spare into position so teaching can continue, and the failed lamp is replaced later.

Can chemical reactions be shown on the stage?

Yes, in shallow transparent dishes. Colour changes, precipitates and crystal growth project clearly. Keep quantities small, avoid anything that gives off harmful fumes near the warm stage, and never place a flame or hot object on the glass.

Why do reactions on the stage speed up?

The lamp warms the stage glass, so solutions in dishes become slightly warmer and evaporate faster. This helps crystal-growth demonstrations but can affect timed reactions, so switch the lamp off between observations if temperature matters.

Is the standard or big deluxe model better for my room?

The standard body suits classrooms and small lecture rooms. The big deluxe body is intended for larger rooms, and the vari-focal version adds adjustment of image size without moving the projector.

How should the head mirror be cleaned?

Blow off loose dust first, then wipe gently with a lens tissue or soft lens cloth. Many projection mirrors are front-surface mirrors whose coating scratches easily, so never rub hard or use abrasive cleaners.
