Description
Technical field
The utility model belongs to optical element technology field, and in particular to a kind of die assembly of aspherical cylindrical mirror.
Background technology
With the increasingly maturation of optical-fiber laser collimation technique, the volume of optical-electric module entirety is less and less, while increasingly
The requirement of high collimation high light beam quality.Cylindrical mirror gradually substitutes other conventional lenses in many fields at present, and aspheric
Face cylindrical mirror can reach optimal state in precision and using effect.
Currently used sphere cylindrical mirror, spherical lens at the same time in the two-dimensional direction have incident light an effect, and cylindrical lens
But only there is identical effect in one-dimensional square.Typical practical applications are come whole into line distortion to light beam with a pair of of cylindrical lens
Shape, with extensiveization that fast axis collimation device is applied, miniaturization and integrated demand are more and more urgent, but it is saturating to be limited to current column
The devices such as mirror element, at present collimater can only use spherical lens and sphere cylindrical mirror, the distortion of imaging is larger, can not high beam
Quality.Fast axis collimation device is compact, high performance aspherical cylindrical mirror, it is designed it is intended that beam shaping and laser diode are accurate
Straight application provides support, the design and high-NA of its aspherical cylinder enable it to be while high light beam quality is maintained
The output of one whole laser diode provides uniform optical collimation.
