The well-known rangefinders that include monitors can no longer meet today's needs, and another rangefinder with a new architecture is needed to simultaneously increase the brightness of the display without affecting the background color.

有鑑於此，本發明之主要目的在於提供一種測距儀及其顯示器鏡組裝置，可同時提高顯示器之亮度又不影響背景顏色，對視覺效果有極大改善。 In view of this, the main purpose of the present invention is to provide a rangefinder and its display mirror device, which can simultaneously increase the brightness of the display without affecting the background color, and greatly improve the visual effect.

The ridge-shaped 稜鏡15 includes a ninth surface 151, a tenth surface 152, and a ridged surface 153. The ninth surface 151 of the ridge-shaped 珜鏡15 faces the second surface 112 of the first 稜鏡11. As shown in FIG. 1C, the angle 136 between the fourth surface 131 and the fifth surface 132 of the second 珜鏡 13 is equal to 101.45 degrees, the angle 137 between the fifth surface 132 and the sixth surface 133 is equal to 90 degrees, and the sixth surface 133 is The angle 138 of the seventh surface 134 is equal to 112.5 degrees, the angle 139 of the seventh surface 134 and the eighth surface 135 is equal to 135 degrees, and the angle 140 of the eighth surface 135 and the fourth surface 131 is equal to 101.05 degrees.

當一可見光2入射第一稜鏡11後，將直接穿透第一面111射向第二面112，射向第二面112的可見光2將發生全反射，使得可見光2改變行進方向射向第三面113及光學多層膜17，因為光學多層膜17允許紅 外光通過，可見光將部份穿透部份被反射，所以部份的可見光2將被反射改變行進方向射向第二面112，且由第二面112射出第一稜鏡11再入射屋脊型稜鏡15，射向屋脊型稜鏡15的可見光2將直接穿透第九面151，接著可見光2將分別於第十面152、屋脊面153及第九面1發發生全反射改變行進方向，最後由第十面152射出屋脊型稜鏡15。 When a visible light 2 enters the first 珜鏡11, it will directly penetrate the first surface 111 to the second surface 112, and the visible light 2 directed to the second surface 112 will be totally reflected, so that the visible light 2 changes the direction of travel and hits the first Three sides 113 and optical multilayer film 17, because the optical multilayer film 17 allows red When the external light passes through, the visible light will partially penetrate through and be reflected, so part of the visible light 2 will be reflected to change the direction of travel to the second surface 112, and the second surface 112 will emit the first 珜鏡 11 and then enter the roof type In 珜鏡15, the visible light 2 directed to the ridge-type 珜鏡15 will directly penetrate the ninth surface 151, and then the visible light 2 will be totally reflected on the tenth surface 152, the roof surface 153 and the ninth surface 1 to change the direction of travel, Finally, the tenth face 152 shoots out the ridge-shaped 珜鏡15.

當另一可見光71由第八面135入射第二稜鏡13後，將直接射向第五面132、光學多層膜17及第三面113，可見光71將直接穿透第五面132，因為光學多層膜17允許紅外光通過，可見光將部份穿透部份被反射，所以部份的可見光71將穿透光學多層膜17，由第三面113入射第一稜鏡11，最後由向第二面112射出第一稜鏡11再入射屋脊型稜鏡15，射向屋脊型稜鏡15的可見光71將直接穿透第九面151，接著可見光71將分別於第十面152、屋脊面153及第九面151發生全反射改變行進方向，最後由第十面152射出屋脊型稜鏡15。 When another visible light 71 enters the second prism 13 from the eighth surface 135, it will directly hit the fifth surface 132, the optical multilayer film 17 and the third surface 113, and the visible light 71 will directly penetrate the fifth surface 132 because of the optical The multilayer film 17 allows infrared light to pass through, and visible light will partially penetrate through and be reflected, so part of the visible light 71 will penetrate through the optical multilayer film 17, enter the first tincture 11 from the third surface 113, and finally pass from the second The surface 112 emits the first 稜鏡11 and then enters the ridge-type 鏜鏡15, the visible light 71 directed to the ridge-type 鏜鏡15 will directly penetrate the ninth surface 151, and then the visible light 71 will be on the tenth surface 152, the ridge surface 153 and The ninth surface 151 undergoes total reflection to change the direction of travel, and finally the tenth surface 152 shoots out of the ridge-shaped henna 15.

上述可見光2與可見光71在第二面112重合。 The visible light 2 and the visible light 71 overlap on the second surface 112.

請參考第1B圖，當一紅外光201R入射第一稜鏡11後，將直接穿透第一面111射向第二面112，射向第二面112的紅外光201R發生全反射，使得紅外光201R改變行進方向射向第三面113及光學多層膜17，因為光學多層膜17允許紅外光通過，可見光將部份穿透部份被反射，所以紅外光201R將直接穿透第三面113及光學多層膜17，由第五面132入射第二稜鏡13，射入第二稜鏡13的紅外光201R將直接穿透第七面134，由第七面134射出第二稜鏡13。 Please refer to FIG. 1B. When an infrared light 201R enters the first prism 11, it will directly penetrate the first surface 111 toward the second surface 112, and the infrared light 201R directed toward the second surface 112 will be totally reflected, making the infrared The light 201R changes its direction of travel and strikes the third surface 113 and the optical multilayer film 17. Because the optical multilayer film 17 allows infrared light to pass through, visible light will partially penetrate and be reflected, so infrared light 201R will directly penetrate the third surface 113 And the optical multilayer film 17, the second yam 13 is incident from the fifth surface 132, and the infrared light 201R incident on the second yam 13 will directly penetrate the seventh surface 134, and the second yam 13 is emitted from the seventh surface 134.

綜上所述，當可見光2及紅外光201R同時由第一面111入 射分合光稜鏡裝置10，可見光2及紅外光201R最後將被分光朝不同方向前進，可見光2將從第十面152射出分合光稜鏡裝置10，其行進方向沒有改變，紅外光201R將從第七面134射出分光合光稜鏡裝置10，其行進方向改變。 In summary, when visible light 2 and infrared light 201R are simultaneously entered from the first surface 111 The split light beam device 10, the visible light 2 and the infrared light 201R will finally be split into different directions, and the visible light 2 will exit the split light beam device 10 from the tenth surface 152, the direction of travel is unchanged, and the infrared light 201R The beam splitting device 10 is emitted from the seventh surface 134, and its traveling direction is changed.
