Projection Lenses

• 

Projection lensand photographic lens is a pair of opposite lenses, the camera lens is used to image the outside world to the CCD or COMS in the digital format, on the other hand the projection lens designto digital format images projected onto the screen.

From the optical design point of view of these two lenses are no different, because the optical path is reversible. However, they still have some differences. First, the photographic lens is generally iris adjustable diaphragm, which control in the photography industry is known as the aperture. tv lensesgenerally in order to maximize the output illumination, aperture stop is not adjustable.

Second, the projector lensis generally fixed focus lens, even zoom lens projectors, the zoom ratio is generally not greater than 2, consumer digital camera zoom ratio are normally more than 3, only the SLR digital camera with fixed focus Lens or a lens with a zoom ratio less than 3.

Third, the lens of different caliber, projection lens diameter is generally much larger than the camera lens.

At Hyperion Optics we develop projection lensesas following:

Short focus (ultra-short focal length) lens, which is used to project large-screen short-range

Medium focal length lens for normal distance projection

Telephoto (super telephoto) lens, for long-range projection of small screen

In addition to that there is a ball screen lens, it is a single lens shot surface

We can design and produce high performance projection lens, the maximum resolution of up to 4K, projection ratio can reach 0.8: 1, which means that the distance of one meter projection of 60-inch screen.

The following table shows the relationship between the projection ratio and the focal length

Now, with the increasing proportion of widescreen video, deformation projection lens has gradually begun to penetrate into the market. Compared to traditional projection lens + deformation lens, the deformation projection lens structure is more compact, better image quality, lower prices.

We have a wealth of experience in design and manufacturing, and we can make performance / price balance designs based on different chip sizes, resolutions, and projection ratios.
