Abstract
The invention relates to a pipe cap lens for encapsulating a laser and converging rays. A positioning surface of a pipe cap in a traditional product is a plane and linearly contacts with a lens, therefore, the positioning area is too small and the accuracy is influenced. The pipe cap lens for encapsulating a laser and converging rays is characterized in that the positioning surface in the pipe cap is concavely spherical, and the spherical radius of the positioning surface is approximate to the spherical radius of the lens so that the pipe cap and the lens can be favorably combined to increase the positioning area and improve the positioning accuracy. The pipe cap lens for encapsulating the laser and the converging rays comprises a lens (1), a pipe cap (2) and a binder (3), wherein the pipe cap (2) is provided with a concave spherical positioning surface, the spherical radius of the positioning surface is approximate to the spherical radius of the lens (1) which is fixed on the positioning surface through the binder (3), and the binder (3), i.e. an adhesive or glass with a low melting point, is mounted at the joint of the lens (1) and the pipe cap (2).
Description
Technical field
The present invention relates to a kind of pipe cap lens, belong to optical-fibre communications laser module field.
Technical background
Pipe cap lens is used for the encapsulation of laser instrument, can converge light simultaneously.The locating surface of pipe cap is the plane in the existing product, and is the line contact between the lens, and location area is too little, influences precision.
The innovation and creation content
Difference of the present invention is that the locating surface of pipe cap is a concave ball shape, the spherical radius of locating surface is close with the spherical radius of lens, the two can well in conjunction with, increased the area of location, improved bearing accuracy.
Concrete scheme is: comprise lens (1), pipe cap (2), bond (3), pipe cap (2) has the locating surface of a concave ball shape, the spherical radius of the spherical radius of locating surface and lens (1) is close, and lens (1) are fixed on this locating surface by bond (3).Bond (3) is placed in the junction of lens (1) and pipe cap (2).Bond (3) is a glue, also can be low-melting glass.
Description of drawings
Accompanying drawing is the synoptic diagram of the embodiment of the invention.
Embodiment
Further describe embodiments of the invention below in conjunction with accompanying drawing.
