AI Technical Summary

Technical Problem

Existing optical devices face challenges in easily and quickly adjusting the distance between optical components to maintain high light transmission efficiency.

Method used

The optical device incorporates a transparent component interposed between the optical fiber and lens, which increases the distance between the optical components, allowing for easier adjustment by selecting a component with the appropriate thickness from a range of options, and includes a support member with a thermal expansion coefficient matching the base to stabilize the assembly.

Benefits of technology

This configuration enables faster and more precise adjustment of component distances, reducing manufacturing effort and cost while maintaining high light transmission efficiency and stability under thermal changes.

Abstract

To provide an optical device having such an improved new configuration as to more easily or more quickly adjust, for example, a distance between two optical components, and a method for manufacturing the optical device.SOLUTION: An optical device includes, for example, a first optical component for transmitting light between one end and the other end, a second optical component for bundling light at one end and coupling the light, or collimating the light emitted from the one end, and a transmission component which is interposed between the first optical component and the second optical component, transmits light emitted from the one end or the light incident on the one end, and makes a distance between the second optical component and the one end longer than that when there is no transmission component. The first optical component may be an optical fiber. The optical device may include a relaxation member for reducing intensity of the light on the interface.SELECTED DRAWING: Figure 1
