| 英文摘要 | PURPOSE:To lock a lens at a fixed position only by inserting it into a hole so as to facilitate the positioning by forming projections around a lens in advance, and locking it inside a lens holding member hole using these lens projections, and fixing this locking part with low melting point glass. CONSTITUTION:A holding member hole 3 has a taper part 4, wherein the center is made the same axis, and a cylinder part 5, and the depths of the taper part and the cylinder part are made in the rate of 1: And when a spherical lens 2 is fixed in the hole of a spherical lens fixing base 7 having a hemispherical hole and a split ring 6 made of sapphire material is set in the spherical lens 2, since the inside diameter of the split ring 6 is a little smaller than the diameter of the lens, the split ring 6 is fixed in the position which includes the meridian of the spherical lens 2 by the elastic force of a spring. Next, the spherical lens set with the split ring 6 is taken out and is inserted into a lens holding member hole 3. And it is covered with paste 8 and is heated to about 500 deg.C and then it is kept in the fused condition for about one minute. Thereafter, by naturally cooling it, the glass is baked and this part is fixed. |
