Embodiment
Hereinafter with reference to relevant drawings, the optical element film coated appliance according to preferred embodiment of the present invention is described, wherein components identical will be illustrated with identical reference marks.
Please refer to Fig. 3～shown in Figure 5, comprise a load-carrying unit 31, two retaining elements 32, one first lid 33, and one second lid 34 according to the optical element film coated appliance 3 of preferred embodiment of the present invention.In the present embodiment, the substrate 4 of two colored drum spectral filters of optical element film coated appliance 3 clamping simultaneously is to carry out film-plating process, as forming the film-plating process of anti-reflecting layer.
Load-carrying unit 31 has two carrying recesses 311 and two retaining element connection sections 313, wherein, carrying recess 311 is positioned at the outer wall and the substrate 4 in order to carry colored drum spectral filter respectively of load-carrying unit 31, and retaining element connection section 313 lays respectively at around the carrying recess 311.In the present embodiment, each radian that carries recess 311 is respectively 120 °, so that cooperate the shape of substrate 4 of the colored drum spectral filter of required carrying, at this moment, the convex surface of substrate 4 is provided with towards carrying recess 311, so that allow substrate 4 concave surface outwardly, so in follow-up film-plating process, can form plated film in the concave surface of substrate 4; Each retaining element connection section 313 axis direction setting of parallel load-carrying unit 31 respectively.In addition, load-carrying unit 31 more comprises the portion 315 that is rotatably connected, the place, axle center that it is positioned at an end of load-carrying unit 31 and is arranged at load-carrying unit 31; At this moment, the portion 315 that is rotatably connected can be used for being connected (not shown) with a swivel bearing, so that utilize swivel bearing to come driven rotary load-carrying unit 31.
