Definitions

  • the present invention relates to fee method of forming an air gap for manufacturing a high performance polarizing prism for a polarization watch.
  • the high performance polarizing prisms are more increasingly needed in public health as well as the laser technology because it is effective for prevention and cure of diseases including the increase of the amount of the circulating blood flow in human body, typically in the brain and heart, and recovering various metabolic disorders.
  • the polarizing prisms of which the interface between two right- triangle prisms is connected by an optical adhesive have a big Length/Aperture ratio, 2.5-3.0, and so they can't be used in the limited structures such as a ring or a watch.
  • the objective of the present invention is to establish the method of forming an air gap for manufacturing a high performance polarizing prism for a polarization watch which has high transmittancy, high extinction ratio and small Length/Aperture ratio.
  • the method of forming an air gap using the screen printing comprises the following steps:
  • the screen is printed down for a certain time after adhered closely to the positive film on the glass plate of the printing-down apparatus, and then is developed in the water at ordinary temperature.
  • the prisms are fixed by according the air interface of the printed prism with the air interface of the unprinted one which has the same optical characteristics as the printed one and putting them in an acrylic resin case for a polarizing prism in a watch.
  • the high performance polarizing prism manufactured like this shows various beneficial effects for human body by being installed in the limited structures such as a polarization watch.
  • Fig. 1 shows a right-triangle prism used in manufacturing a high performance prism according to an embodiment of the present invention.
  • Fig. 2 shows a positive film of the original painting used in the screen printing according to an embodiment of the present invention.
  • Fig. 3 shows the screen printed down and developed according to an embodiment of the present invention.
  • Fig. 4 shows the air interface of the printed right-triangle prism according to an embodiment of the present invention.
  • Fig. 5 shows the high performance polarizing prism fixed in an acrylic resin case according to an embodiment of the present invention.
  • Fig. 6 shows a polarization watch where a high performance polarizing prism is installed according to an embodiment of the present invention.
  • Fig. 1 shows a right-triangle prism used in manufacturing a high performance prism according to an embodiment of the present invention.
  • the air interface 11 of the right-triangle prism 10 is a rectangle and is screen-printed.
  • “L” and “A” is the length and aperture of the right-triangle prism 10, and the angle ⁇ is 90 degrees.
  • a iceland spar crystal with high optical quality that has no straie, cracks, diffusion and impurities is, after adjusting its optical axis, cut with a cutting angle, 49°63', and separately processed. Then two right-triangle prisms which have the same optical characteristics are taken.
  • Fig. 2 shows a positive film of the original painting used in the screen printing according to an embodiment of the present invention.
  • Fig.2 only two zonal black lines 21 are on a positive film.
  • the dotted portion indicates the same rectangle as the air interface 11 of the right-triangle prism.
  • the zonal black lines 21 are accorded with each one of two edges of the air interface 11 of the right-triangle prism 10.
  • Fig. 3 shows the screen printed down- and developed according to an embodiment of the present invention.
  • a screen 30 coated with the sensitizer is printed down the illuminated portion 31 is hardened. And then only the image 32 remains on it as the screen 30 is developed.
  • the screen 30 printed down is developed in the water at ordinary temperature and as the result the sensitizer on the portion under the zonal black line 21 is removed, and the image 32 is made which has the same size as the zonal black line 21.
  • Fig. 4 shows the air interface of the printed right-triangle prism according to an embodiment of the present invention.
  • the printed layer 41 is made.
  • the thickness of the printed layer 41 is the same as the screen 30 and its width is the same as the zonal black line 21. In one embodiment the thickness of the screen 30 is 0.09 mm and so the width of the printed layer 41 is also 0.09 mm.
  • Fig. 5 shows the high performance polarizing prism fixed in an acrylic resin case according to an embodiment of the present invention.
  • the imprinted right-triangle prism 52 is on the printed right-triangle prism 51 and both of them are fixed in an acrylic resin case 53.
  • the air gap between those two prisms is maintained constant. This air gap is as thick as the printed layer 41 and after all its thickness is the same as the screen.
  • the wavelength range of the high performance polarizing prism is 215 to 2300 run and the prism has a high extinction ratio, 1 X 10 "6 .
  • Fig. € shows a polarization watch where a high performance polarizing prism is installed according to an embodiment of the present invention.
  • a high performance polarizing prism 61 is installed on the right of the polarization watch 61.
  • the polarization watch 60 is an analogue crystal clock and the high performance polarizing prism 61 is cube-shaped 10 mm long, 7 mm wide and 6 mm high.
