Introduction
Prismasonic anamorphic lens is a high quality optical product to boost your digital projector to the next level. It makes a variable horizontal expand to the projected image, thus supporting perfectly the constant height, 2.37:1 CinemaScope setup, which is also used in the real movie theaters. Because the lens is variable, you also can easily get the 'pass through' mode for the 16:9 material without removing the lens, and thus maintaining the constant height with the full panel resolution. Also other aspects, such as 1.85:1 and 2.00:1 are possible due to the unique feature of a variable Prismasonic lens.
The other very significant advantage is that when the conversions are done optically, there will be NO need for the horizontal masking of the 2.37:1 screen. This is due to the fact that there will be NO light spill from the LCD/DLP panel with either aspect modes, which is a problem if the conversions are made electrically by the projector or scaler/processor.
H-850 Series (Manual and Remote controlled)
The H-850 series models have two optical elements. The prisms of H-850 series have been finished by the optical glass using the highest possible specification parameters during the manufacturing process. Moreover, all the optical surfaces have multicoated anti-reflection (AR) surfaces to prevent reflections and ghosting, and to maximize the light output of the projector. The H-850M has manual control knobs to expand the image to full 2.37:1 and to squeeze it back to 'pass' mode. In addition to the instructive label printings there are adjustable terminal stops for both prisms and both modes, so the tuning can be easily operated to match the different screens and setups perfectly. Compared to the preceding H-700 series, the H-850 series accepts ~20 % bigger beams. Also the prisms have been further optimized, so that there exists a bit less chromatic aberration compared to H-700 series lenses. The table stand is more professional having now the individual controls for the height and tilt adjustments. This lens is available in silver or black finished aluminium. As a nice feature the housing has a removable bottom plate, so cleaning the prims from both sides is possible if needed.

HD-5000 Series (Manual and Remote controlled)
The HD-5000 series models have five optical elements. The prisms of HD-5000 series have been finished by the optical glass using the highest possible surface accuracy parameters during the manufacturing process. In addition to this the prisms are achromatic, which means that both prisms are made by two glass materials having different optical properties. This specific technology eliminates the chromatic aberration (color fringing) from the image. An additional optical front element FE perfectly corrects the focus of an anamorphic expand, and also eliminates a slight focus shift between the 'stretch' and 'pass' modes, if compared to the non-FE lens models. Moreover, all the optical surfaces have the multicoated anti-reflection (AR) surfaces to prevent the reflections, and maximize the light output of your projector.
Compared to the preceeding H-FE1500 series, the HD-5000 series accepts ~20 % bigger beams. Also the achromatic prisms have been further optimized, so that there exists NO chromatic in a working throw range (down to 1.5). The table stand is more professional having now the individual controls for the height and tilt adjustments.
The operation of HD-5000R lens is very simple. The other button of remote control expands the image to 2.37:1 and the other squeezes it back to 'pass through' mode. There are adjustable terminal stops for the both prisms and both modes, so the tuning can be easily operated to match the different screens or setups perfectly.
The power for the lens unit is fed by the 12 volts AC/DC adaptor. The motors are very silent, and it takes about 2 seconds to go from end to end. This speed enables you also to stop the prisms quite accurate to the intermediate positions such as 1.85:1 or 2.00:1.
The remote control uses 12 volts battery. It has two powerful IR leds, and can be controlled without problems even at the very largest HT rooms from the seat, via screen, back to lens unit. If one has an universal remote controller, it is possible to IR learn it.
The HD-5000M has manual control knobs to expand the image to full 2.37:1 and to squeeze it back to 'pass' mode. In addition to the instructive label printings there are adjustable terminal stops for both prisms and both modes, so the tuning can be easily operated to match the different screens and setups perfectly.
