Types of projectors lenses

Types of projectors lenses

There are a few different types of lenses used in projectors. The most common are coated and uncoated lenses. Coated lenses have a layer of material that helps reduce glare and reflections, and uncoated lenses do not have this coating.

Other types of projector lens are: 

Convex Lens: Convex Lenses are some of the most common lenses in projectors. They are the basic requirements projectors need to deliver pictures because they enlarge the projected content size. This gives one the ability to mount or place their projector anywhere they want. That’s a trait that’s pretty standard in projectors nowadays regardless of where it’s placed.

Without having this lens one would have to adjust the image by moving the projector forward and backwards until the sweet spot is found. An activity that would be frustrating.

A lens with a 1.2x zoom factor will allow the image size to be increased by 20 percent. That’s considered acceptable by most, especially if the projector is going to be used for a home entertainment system.

Short throw Lens 

This might be kind of obvious but short throw lenses are typically found in short-throw (or in some cases ultra short throw) projectors.

Many people purchase short-throw projectors because they don’t have a ton of room for a 10 ft distance between their screen and their projector.

A wide-angle lens can be placed on any projector model, but it isn’t usually recommended. It’s considered an alternative if you need to move your regular projector closer to the screen but remember that the lumen rating of your projector won’t change which can result in distortion or hotspots.

Short throw lenses have shorter focal lengths, which makes a wider view field. It creates a distance between the projector and the image that is physically lackinng.

Short throw projectors can range from anywhere from 0 to 8 ft from the screen, a range that would make the image appear smaller or actually cut parts of the image off. Wide angle lens create wider frames that ensure the entire image is viewed.

Long throw Lens

On the opposite end of the spectrum we have long throw lens. According to the title, one would think that long throw is the exact opposite of short throw – that isn’t necessarily true.

When projectors can’t be positioned directly in front of the screen, having an interchangeable long throw lens would help achieve the best image quality while also working like a zoom lens. Because the projector is further away, having this lens will enhance the pictures clarity and size on the screen.

One will typically find these lenses in churches, auditoriums and anywhere that requires large audiences since the projector will be behind them. These lenses can also be used at home for anyone who needs a distance over 10 ft between their screen and projector.

Micro Lens 

Micro lenses are incredibly small lenses. They typically have less than a mm diameter. Micro lenses can provide amazing picture quality and are considered a good option for digital projectors. While most projectors are compatible, some of the are not.

Because their design is so tiny, the pieces that support the actual lens inside the projector are typically thicker than the actual lens. if you try to use this lens type you’ll want to take the thickness into consideration and make sure it’ll fit.

You’ll also want to take into account if it’s a sophisticated aspherical surface or a spherical convex surface.

Micro lenses with spherical convex surfaces means the lens itself has a single layer that collects and send light to your screen in a focused manner.

Aspherical micro lenses have multiple layers and might be a bit thicker. The layers of the lens work together to clear the image up.

Projectors also have a Micro Lens Array feature. Micro lens and this featured are used synchronously to redirect light that would be lost through out of the lens and through the prism.

By doing so you can increase your picture’s brightness more while also lowering the heat made inside the projector.

Answer to the question

Rubbing alcohol will damage the coatings on your lens, and it is not recommended to use rubbing alcohol to clean any type of projector lens. If you must use something, diluted vinegar or distilled water is better.
