8. DESCRIPTION
8.1 Optics
This product adopts the features of the LV-7215 and other zoom lenses, the aperture
ratio of the LCD panel is large, a 0.79 type (nominally 0.8 type), and the size has been
reduced while achieving high luminosity with a 200 W SHP lamp.
●
1.6
×
wide zoom lens (Same as LV-7215/7210/5210)
This product incorporates a projection lens that has a first rate zoom ratio of 1.6
×
magnification. Constructed of 11 layers in 11 groups, this is a 6-group zoom lens in
the configuration: Neg./Pos./Pos./Neg./Pos./Pos.
By using an aspherical lens (G2, G10) on both sides, the front lens is much smaller
and the number of lenses has been reduced, resulting in the realization of a more
compact wide-angle lens. Also, by using one UD lens (G9) with its error dispersal
characteristics, the occurrences of color aberrations have been suppressed while
achieving high pixelization.
In consideration of the environment, all the glass in the optical system is lead free.
●
Projection distance (Same as LV-7215/7210/5210)
This product can display images with excellent fidelity on 100-inch screens at a throw
distance of 2.5 m.
Refer to the table below for the relationship between the throw distance and the screen
size.
* The projector displays correctly at screen sizes between 40 and 300 inches; the quality of
projections at other screen sizes is not guaranteed.
●
LCD panels
This product consists of opposing 20 mm (0.79 type) LCD panels (without micro-
lenses).
The capacity is essentially the same as the LV-7210.
●
Lamp
This product adopts as its light source the 200 W SHP lamp to achieve luminance of
1500 lm.
However, the output is set to 190 W in order to balance luminance, production of heat,
and power consumption.
