Description
Technical field
The invention belongs to Screen Technology field, particularly to making and the technique for applying thereof of a kind of aqueous projection screen paint.
Background technology
Projection screen paint, is a environment protecting water-based paint, and the screen being applied to projection electronics uses, and is a high-tech
Nano metal reflecting coating, if brushing or roller coating, one layer of projection screen paint of spraying, so that it may so that projection picture reaches best effective
Really.Its application is very wide, be home theater, the displaying of exhibition sale point, meeting room, large stadium such as: cinema, music hall, physical culture
Field, museum, the best product that television station and colony place show.Showing a film in China's 70-80 age uses calico to make
For screen, over time and the progressive industrial development of society, second filial generation product just adds fibrous material cloth conduct by white plastic PU
Screen, can reach waterproof, and spot-resistant, resistance to ag(e)ing are good, convenient with band.The projection screen currently used, the shortcoming being primarily present
It is that refractive power is low, reflective too strong, the light action of image is not up to optimum efficiency！Image there will be refined white, the whitest image,
Form and aspect are unintelligible, also to splice at large-scale projection screen, there is splicing line shortcoming.It addition, be limited to closely at object point and light
Under conditions of axle region, ideal image could be realized.Light is once beyond near axis area, even the light sent from same point
Monochromatic, do not intersect at a bit, say, that will appear from significant aberration yet.Furthermore, what we were run into is to have even mostly
The polychromatic light of continuous spectrum.Because the refractive index of medium becomes (dispersion) with wavelength, so the different wave length sent from same object point
Light, even if near axis area, do not intersect at a bit yet, which forms aberration.Aberration and aberration the most seriously destroy
As ground definition.If (light gathering power) considers in terms of energy, the light beam entering optical system is unsuitable narrow；And in order to make
Visual field is wide, and object also should not be limited in paraxial region.It means that on the one hand require imaging clearly, eliminate as much as aberration
And aberration；On the other hand requiring that again aberration is wide and bright, both may often be such that and can not get both.This is at actual optical instrument
The class contradiction being frequently encountered by problem, in other words, definition and image field energy accumulating degree after mainly imaging is amplified it
Between relations problems.Below also simply consider from the viewpoint of geometric optics.Actually due to the fluctuation property of light, light beam is more
Being restricted, cross section is the least, and diffraction pattern is the most obvious.This will destroy the definition of picture again from another point of view.It is to say, more
Reducing aberration, diffraction will be the most obvious；Avoiding the impact of diffraction, aberration becomes again obvious.This is again another kind of contradiction, or
Saying, this is mainly the relations problems of imaging definition and details resolution degree.In actual optical instrument, going out of these problems
It is now inevitable.In order to make these problems have a suitable process standard, people just pay special attention to weigh optical instrument
The gain and loss of the aspect such as amplifying power, light gathering power and resolving power, in order to match instrument according to some index and actual conditions
Device element, it is achieved the set purpose of instrument.To these problems, we try hard to only make tentatively introducing, without regard to too much in principle
The particular problem of Application Optics.
