Claims

[Claims for Utility Model Registration] 1. An optical semiconductor element, a package for airtightly housing the optical semiconductor element, and a cylindrical holder coaxially joined to the package on the optical axis of the optical semiconductor element; and a lens housed and held in the holder, the lens being held in the holder so as to be slidable in the optical axis direction via a lens holding ring, and an optical axis adjusting means attached to the lens holding ring. an optical semiconductor device collimator, wherein the position in the optical axis direction is set by . 2. The optical axis adjustment means includes a spring that presses the lens holding ring in the optical axis direction within the holder, and a holding section that holds the lens holding ring at a fixed position in the holder against the spring. 2. The optical semiconductor device collimator according to claim 1, further comprising: an optical semiconductor element collimator. 3. The optical semiconductor device collimator according to claim 2, wherein the holding portion is a welding portion that welds the holder and the lens holding ring to each other, or a locking tool that locks the lens holding ring through the holder.
