Title: Laser unit
Inventor: KIMURA AKIYOSHI
IPC: G03G15/04
Filed: 1987-12-26
Abstract: PURPOSE:To absorb the variation of the gap between a laser chip and a collimator lens due to a difference in heat expansion more efficiently by setting the orientation of a flow of molecules of a filler to be contained in a resin part and resin in the direction of the optical axis of a laser beam. CONSTITUTION:The semiconductor laser chip 3 and collimator lens 4 are assembled in one body by an assembly member 2 while the specific gap G is formed. The filler F for varying the linear heat coefficient, on the other hand, is added to the resin raw material of a collimator lens barrel 8. The orientation of the filler and the flow direction of molecules of resin are set in the direction of the optical axis, so the linear expansion coefficient of the resin part in the optical axis direction varies greatly by the filler and the amount of the filer necessary for a linear expansion coefficient for absorbing the variation of the gap by temperature variation can be reduced. Thus, the linear expansion rate is selected to absorb the quantity of the variation of the gap G between the laser chip 3 and collimator lens 4.
