HIGH-PRECISION TELECENTRIC OPTICAL PATH

In order to obtain the best projected image accuracy, a precise 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 pure-glass lens provides an unprecedented resolution of 93 lines 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 fully motorized zoom and focus, plus optical lens shift to adjust the position of the image up to 75% vertically and 30% horizontally.
NERO 4 also includes Perfect Fit, a fully-programmable zoom/focus and lens shift feature which allows the creation of up to 2.40:1 images without the need of an optional anamorphic lens.

 

Spectacularly-high brightness

A new high-power long life 450W lamp enables NERO 4 UHD  to provide up to 5000 ANSI-lumens 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 for shift of the image or of the object. This is important in projection to avoid 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, due to the constant magnification.

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.
