Description
Technical field
The utility model relates to loading fixture technical field more particularly to a kind of fast axis collimation lens loading fixtures.
Background technique
Semiconductor laser is communicating at present, and industry and medical field have many uses general, volume, and photoelectric conversion efficiency is high.
Unique insufficient angle of divergence exactly issued from chip is bigger, it is therefore desirable to increase collimation lens.Due to semiconductor laser
Chip is all micron level, and collimation lens is also very exquisite small, therefore cost of manufacture is more expensive.
In order to solve the problems, such as that micro lens are high-cost, at present in many application fields using cylindrical optical glass rod
As collimation lens, which is about 60~100um, which can use predispersed fiber
The mode of stick-making and drawbench technique produces, therefore cost of manufacture is cheap more than aspheric collimation lens very much.In many collimation journeys
Application scenarios of less demanding are spent, in closely coupling, all generally use this cylindrical glass stick as fast axis collimation lens.
Since the lens surface of all participation laser assembly requires plating anti-reflection film, the glass bar surface of this cylinder is also required to
Plate optical thin film.However since this glass bar is very subtle, and glass material is frangible, this is anti-reflection to circumference plating is done on its surface
Film strips carry out very hang-up, because we can not rotate the glass bar lens of more more than 60 micron diameters simultaneously and ensure that it is not twisted
It is disconnected.
Utility model content
For overcome existing optical glass rod it is easy to damage the technical issues of, it is saturating that the utility model provides a kind of fast axis collimation
Mirror loading fixture.
To achieve the above object, the utility model provides the following technical solutions：A kind of fast axis collimation lens loading fixture, packet
Pedestal, pressing plate, dust cover and optical glass rod are included, wherein the pressing plate side of being set on the base, dust cover is arranged on pressing plate
Side；The pedestal is made of dust-proof bottom plate and the rectangle frame being arranged in above dust-proof bottom plate, wherein dust-proof bottom plate and rectangle frame are
Structure is split, is respectively equipped with silicagel pad above the rectangle frame left and right ends, rectangle frame left and right sides are carved with mark line respectively；Institute
Optical glass rod is stated equipped with several, wherein placement is straightened in each optical glass rod alignment mark line, it is ensured that adjacent two light
It is consistent to learn parallel and spacing between glass bar.
Preferably, the surface of the optical glass rod is coated with anti-reflection optical thin film.
Preferably, the optical glass rod diameter is 60~65 μm, which is 75~85mm.
Preferably, 2.3~2.8mm is spaced between the two adjacent marks line.
Compared with the existing technology, the utility model has the beneficial effects that：It is equidistant and be arranged in parallel more on loading fixture
Optical glass rod is cooperated by dust cover, pressing plate and silicagel pad, to optical glass rod is fixed on fixture, significantly
The breakage rate for reducing optical glass rod, thus greatly reduces production cost.
