Both projectors feature a FUJIFILM unique folded lens. Bending and focusing light to create an image requires a high-precision optical design. By utilizing the optical design software originally developed by FUJIFILM, dozens of elements were combined to create a lens that can be rotated without creating distortion and that projects a high-quality image to every corner of the screen.
Maintaining high resolution without distortion requires precise alignment of the optical axis. Multiple adjustments are optimally combined to deliver a high-quality image.
We overhauled the color design of the Z-projector to increase the color space. The projector boasts a wide variety of customizable controls - including settings for hue, saturation, color temperature, and seven-color tuning - that combine with edge blending to allow images to be displayed effectively using multiple projectors.
The front lens group (Group G1) features a wide-diameter aspherical lens. It is to this wide(Φ87mm)aspherical element with a surface ground to high-precision, single-micron tolerances, that the projector owes its ultra-short throw.
With a throw ratio*1 of 0.34, the projector's ultra-short-throw lens can project images of up to 300-inch from ultra-close range. A 100-inch image can be projected from an ultra-short distance of only 72 cm (28 in.)*2.
- *1 The "throw ratio"(TR) is the throw distance divided by the screen width.
- *2 The distance between the lens and the surface on which the image is projected.
The position of the projected image can be adjusted lens shift range of 70% in the vertical direction and 35% in the horizontal direction (when horizontal projection at 16:10). Furthermore, it is equipped with a function to memorize the lens shift position for each projection direction.
Our projector-lens design techniques are a product of roughly 30 years experience, this has lead to the development of lens barrels capable of maintaining high resolutions even when rotated in six directions on two axes. A compact design has been achieved by combining the lens and imaging system and by optimizing the layout of parts within the projector.
