Overhead Projectors which are also known as OHPs are used to project and
enlarge an image which is on a transparent sheet onto a distant screen for
easy viewing. It is quite an old type of device, yet, widely used in
businesses, schools, colleges and universities. Places such as these have
their own projectors as they are required very frequently. However, an
Overhead Projector Hire is required for events such as conferences,
meetings, exhibitions and similar events. Companies and persons, who won’t
require the use of this electronic device often, opt for a daily rental –
as and when required or if required for period of time, they settle in for
a long term lease.
When the machine is rented out, most of the rental companies offer the
required accessories as well, such as, transparencies, overhead projector
trolleys, projection screens which are in varied sizes etc.
Before renting out the projector make sure that it has all, or at least
most the features that are required to produce a clear picture, such as:
High/low brightness control
Colour fringe control
Safety cut out
Whisper quiet operation
When you call your rental agent for your Overhead Projector Hire, you can
discuss all the important bits of information and check its availability,
before committing yourself to hire it.
A vital point to keep in mind is that the projector should allow the
presenter to write down ideas and points as the discussions are going on,
so that it can be projected instantly onto the screen in order that the
attending delegates can take the notes down. This is a very convenient
feature that most projectors should offer.
If you are a person/company who hires overhead projectors often, it is
important to be familiar with the different types of projectors so that you
will be able to request for the right one according to your event’
requirement. There are 3 general types of projectors:
· Transmissive · Reflective · Opaque
Transmissive : These projectors are generally comprised of a base with a transparent
stage area, a light source inside the base, a projection head mounted above
the stage and a condensing lens system located near the stage for directing
the light towards the projector head. Above the base is a projection head
which includes lenses and a mirror which functions to gather light from the
projector base and redirects it to the distant screen. The projection head
is supported by a post as it is necessary to be adjusted so that the
projected image on the screen may be brought into focus.
Reflective : A reflective overhead projector is used for presentation of an image to
number of viewers.
Opaque : Opaque projectors are similar to the Reflective projectors but are able
to project images of opaque materials and three dimensional objects in
addition to transparencies.
From these three types of basic overhead projector systems, the
Transmissive Projector is the larges and heaviest.
Overhead Projector Hire is a common requirement for event organising. If
you don’t own a machine it is always advantageous to have a sound knowledge
of its technology so that you will hire the most appropriate unit for the
