自聚焦玻璃透镜,与普通球面透镜比较,具有如下优点:容(?)制作很小直径的透镜,一般说来,直径可小到0.2mm。比0.2mm直径小的透镜也是容易制作的,但从分辩本领和像的亮度考虑,透镜直径最好不小于0.2mm;能够制作极短焦距的透镜;能够在透镜端面形成实像;一个自聚焦透镜的光性,相当于几个球面透镜组成的透镜的光性;使制作能弯曲的透镜成为可能。由于这些特点,它将具有广泛的应用。自聚焦玻璃 Self-focusing glass lenses, compared with ordinary spherical lenses, has the following advantages: Volume (?) Production of small diameter lens, in general, the diameter can be as small as 0.2mm. A lens smaller than 0.2 mm in diameter is also easy to manufacture, but the lens diameter is preferably not less than 0.2 mm in terms of the resolution and the brightness of the image, a lens with an extremely short focal length, a real image at the end face of the lens, a self- Of the light, the equivalent of a few spherical lens composed of the light of the lens; make curved lenses made possible. Due to these characteristics, it will have a wide range of applications. Self-focusing glass
