Descrizione

Lente anamorfica con controllo manuale, permette la visione di un film cinemascope su apposito schemo anamorfico.
la lente è adatta per ogni videoproiettore, imposrtant eè che il proiettore in possesso abbia la funzione VERTICAL STRETCH,
oppure in alcuni casi coincide con la modalità di visione "LETTER BOX".
Introduction

Prismasonic anamorphic lens is a high precision optical product, which boosts a real cinematic atmosphere at your home Theater. It makes a variable horizontal expand from 1 up to 1.33* for the projected image thus supporting perfectly the constant height 2.37:1 CinemaScope setup. This special optical system is also used at every commercial movie theater. The 'pass' mode of the lens makes it possible to produce a normal wide screen picture for the 16:9 source material, without removing the lens. Also the other aspect ratios, such as 1.85:1 and 2.00:1 are possible due to the unique feature of a variable Prismasonic lens. This means that despite of the aspect of a source material, your projector always presents a constant picture height with the full panel resolution.

Additional significant advantage is that when the conversions are done optically, there will be NO need for the horizontal masking of a 2.37:1 screen. This is due to the fact that there is NO light spill from the display panel of projector with different aspect ratios, which may be a problem if the aspect ratio processing is made electrically by a projector or scaler.

H-850M (Manual 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.
