Description

Powered by custom made, high precision optics, the Prismasonic P100M brings a real cinematic atmosphere in your own home theatre the way the director intended. The lens produces a variable horizontal expansion to the projected image from factors of 1.0 up to 1.35, thus supporting perfectly the constant height 2.40:1 Cinemascope setup. An internal ‘pass’ mode makes it possible to produce a normal wide screen picture with a 1.78:1 source material, without removing the lens. Also, the other aspect ratios, such as 1.85:1 and 2.0:1 are possible due to this unique feature of a variable Prismasonic lens. This all means that despite the aspect of source material, your projector always presents a constant picture height with the full panel resolution, exactly as in real movie theatres. Also with the 2.4:1 aspect ratio produced by the lens, the picture has around 15% more luminance compared to the zoomed picture of same size and projected from the same throw distance. This is due to taking the unused pixels of black bars into use with the aid of our anamorphic lens.

The prisms of the P-100 series have been finished by the optical glass using the highest possible specification parameters during the manufacturing process. In order to correct the chromatic aberration, the product has achromatic optics, which means that both lenses are made by two glass materials of different optical properties. All the air-glass surfaces have broad band anti-reflection coatings to prevent reflections and ghosting and to maximize the light output of the projector. The additional optical Front Element corrects the focus of an anamorphic expand, simultaneously for all horizontal expand factors.

The lens is available in black finished aluminium. A professional table stand has friction-based, individual controls for both height and tilt adjustments. Both shelf and ceiling mounting is conceivable. As a nice feature, the housing has a removable bottom plate. Thus it is convenient to clean the optics from both sides.

This manually controlled lens has two knobs on top to adjust the aspect ratio. The one control position expands the image to fill the 2.40:1 screen, while the other returns it back to 1.78:1. In addition to the instructive label printings, there are adjustable terminal stops for both prisms and both modes, so the initial setup can easily be operated to match the different screens and projectors perfectly.

Prismasonic P100M Lens:

The optics of prismatic lens is based on two achromatic prisms and a spherical focus correction element. All the air-glass surfaces have broadband anti-reflection coatings to prevent the reflections, and to maximize the light output of the system. Achromatic optics means that both prisms are made of two prism components of opposite polarity and different optical properties. The components are eventually seamlessly bonded together. The formed pair of achromatic doublets effectively reduces the chromatic aberration, which would occur as a colour fringing in a picture projected through the single prisms.
