An apparatus for inspecting a collimator including a pigtail formed with first and second fibers, a GRIN lens disposed coaxially relative to the pigtail, and a glass tube supporting the pigtail and the GRIN lens in a single unit, to inspect optical properties of the collimator, comprising an inspection table; a gripping part, which is provided on the inspection table, gripping the collimator subject to inspection; a light supplying part transmitting a predetermined optical signal to the first fiber; a light receiving part, which is connected to the second fiber, receiving an optical signal returned from the second fiber, entering the first fiber; a measuring part calculating a value of the predetermined optical signal, which entered the first fiber, and a value of the optical signal, which returned from the second fiber; and an image displaying part displaying the value obtained from the measuring part. With this configuration, the collimator can be inspected in part, thereby increasing the product reliability of the collimator.
Description
technical field [0001] The invention relates to a device for detecting collimator. Background technique [0002] A collimator is a device used for optical communication, which converts the incident light from a light source into a parallel beam. Collimators are generally used as components of various devices including optical communication devices, semiconductor devices, and the like. [0003] Such as figure 1 As shown, a typical collimator includes a lead wire 12 and a GRIN (gradient index) lens 14, both of which are arranged on a coaxial line; a glass tube 15 that accommodates and supports the lead wire 12 and the GRIN lens 14; and a tubular metal sleeve A barrel 16 which protects the glass tube 15 on the outside. [0004] In the lead wire 12 made of glass, there are a pair of optical fibers 13a and 13b forming an incident path for predetermined light into one end of the lead wire 12, and the light enters the lead wire 12 through the incident path. The other end of the...
