HIGH-PRECISION TELECENTRIC OPTICAL PATH

In order to obtain the best projected image accuracy, a delicate balance is required between the light engine, the DLP® chipset and the video processing electronics. Building on its heritage of high-end light engine design, SIM2 has invested heavily in the development of a high-precision telecentric optical system. The SIM2 NERO 4S UHD HDR models’ pure-glass lens provides an unprecedented resolution of 93 line pairs per millimeter to guarantee exceptional on-screen clarity.
Special coatings have been applied to the optical components to further enhance image and color performance.Installation aids include wide ratio zoom lens (2x zoom) and fully motorized focus and zoom adjustments, plus optical lens shift to adjust the position of the image up to +/- 75% vertically and up to +/- 30% horizontally. 
The 2x zoom lens provides easy, simple, effortless, and accurate setup in most size rooms and applications; for instance, for a 140-inch diagonal screen size, the projector can be installed from between 4.2 to 8.3 meters (from 13.7' to 27.3') from the screen. 

 

 

Spectacularly-high brightness

A new high-power long life 450W lamp enables NERO 4S UHD HDR to provide up to 6000 ANSI-lumens (>10,000 ANSI-Lumens on Dual NERO 4S UHD HDR) for vibrant and clear images across the whole screen.

Why a Telecentric Optical System

In a telecentric optical system the chief ray is parallel to the optical axis. The optical system can be telecentric in the object space, in the image space or in both of them.

The telecentric system has no perspective error.

The size of an object moving towards or far from the lens appears to be always the same. For this reason telecentric lenses are used widely for industrial application where precise measurements are required.

The main advantage of a telecentric system is its independence from the position of the object or of the image.

The telecentricity guarantees that there is no magnification change during refocusing.

​This is particularly useful in projection systems if vertical and / or horizontal shift ​ are needed.

A further advantage of telecentric lenses is their low distortion. The rays cross the telecentric lens elements forming small AOI ​(Angle of Incident)​ and this guarantees good performance ​in terms of color separation and glare.
