Overhead projectors were a staple in classrooms and offices when the models we see today did not exist. The ones we have today are a mixture of the old and new technology to give you the finest of both worlds.
Being more affordable is one of the reasons why you still see them at some schools or offices.
The larger and older models come with a light source, a fan to cool the system, and a focusing lens. On the top, you have a mirror that helps to project the slide you placed.
Slides here are also printed or handwritten on transparent sheets so the light can pass through and give you a projection.
The other one is the newer kind, where you can connect the projector to any other multimedia device using a wireless connection or a USB and have the projection ready.
This kind is mostly used for entertainment purposes, where the older models are for presentations.

Overhead Projectors Buying Guide
The resolution of a projector refers to the number of pixels it has. These pixels come together to create the image on the screen. Hence, the more pixels you have, the smoother the projection.
When you see resolutions in two numbers such as 1280 x 720, this tells you that you have 1280 pixels horizontally, and 720 vertically.
For a home theatre, you should opt for a resolution of a minimum of 720p. This will give you the details you seek from movies, sports, or other entertainment. The latest and finest resolution we have now is the 4K. It means you get 4 times the resolution of a 1080p screen. However, they tend to be very expensive, and hence are not used on a small scale.
Offices do not need the splurge since there are less details and colors to be projected. Schools tend to project both videos and data, and for these mixed projections opt for a mixed resolution. We recommend the 1280×800 which would do the job well.
If you look at all the top overhead projectors, you will see that they all have a top-notch lens. For this kind of projector specifically, lens quality plays a big part in the projection.
You have three basic kinds- the singlet, doublet, and triplet. Triplet lens have a superior projection quality than the previous two, and hence costs a little higher as well.
If you use this for offices where the slides include detailed spreadsheets, intricate graphics, or colored sheets, then going for the triplet is your best option.
On the other hand, if the slides are monochrome and texts are printed in large clear fonts, a singlet would suffice.
The brightness of a projector is determined by its lumen count. The higher this count is, the higher the brightness will be, and vice versa. This brightness need varies from place to place and changes with work needs.
For example, if you plan on using the projector for presentations in a small meeting room, you can easily work with 2500 lumens if you can dim the lights. And if the lights need to be on, which is the case for most offices and schools, you need a higher count of around 3000 lumens.
A home theatre system on the other hand does not need the higher brightness since you can easily turn off all the lights. This saves you money because you can settle for lumen counts below 2500 which tend to be cheaper.
This applies to the overhead projectors that have a head. This is important to consider if you want longevity in the device. And let us face it, we all want that.
Closed head projectors keep out all the dust, and in case you are moving it, you will not find fingerprints on it either which can be a hassle to remove.
Open head projectors on the other hand are easier to clean and they are more compact, making it easier to move.
If you value portability more, go for this. Otherwise, the closed head will serve you well.
When you are looking for the best overhead projector, you will come across a mixture of older and newer models together. They both serve different purposes and hence are chosen by different professions. But no matter which you choose to go with, there are certain factors to keep in check.
Points like the resolution, brightness, lamp life apply to every projector out there, making it crucial for you to check them before making a purchase. To conclude, your next projector can be found from this list, all you have to do is take a careful look at it.
