Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optoelectronic unit measuring devices face instability and increased measurement time due to frequent movement of objective and imaging lenses, leading to potential measurement errors and prolonged testing processes.
Innovation Solution
An optoelectronic unit measuring device that includes an objective lens, an imaging lens, a photographing lens, and a focus adjustment module, allowing for the adjustment of focus positions between the imaging and photographing lenses without moving the objective or imaging lenses, using light transmitting members to refract light and change focus positions dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the objective lens or imaging lens is moved frequently to change focus positions for different measurements, then the focus position can be adjusted, but the optical system stability deteriorates and measurement errors increase
Solution Approach 1:
The patent introduces a light transmitting member (such as a transparent plate or prism) as an intermediary element in the optical path between the imaging lens and photographing lens. This intermediary modifies the light path to achieve focus position adjustment without moving the objective or imaging lenses, thereby maintaining optical system stability while enabling focus adjustment capability
Solution Approach 2:
The patent replaces the mechanical movement of lenses (objective lens or imaging lens) with an optical method using light transmitting members. Instead of mechanically moving heavy lenses to change focus, the system uses optical elements to refract or redirect light, achieving the same effect with minimal mechanical movement and maintaining system stability
2Adaptability or versatility
If the objective lens or imaging lens is moved frequently to change focus positions, then focus adjustment is achieved, but measurement time increases
Solution Approach 1:
The patent replaces slow mechanical lens movement with faster optical switching using light transmitting members. The light transmitting members can be quickly inserted or switched in the optical path without the time-consuming mechanical movement of heavy lenses, thereby improving measurement efficiency while maintaining focus adjustment capability
Solution Approach 2:
The light transmitting members are pre-positioned in ready-to-use locations within the optical path. When focus adjustment is needed, the system simply switches between pre-positioned elements rather than moving lenses during measurement, reducing adjustment time and improving measurement throughput

Function Achieved in This Case
This solution maintains optical system stability while accelerating measurement efficiency by allowing for quick adjustments in focus positions, enabling precise measurement of beam characteristics without moving the objective or imaging lenses, thus reducing measurement time and errors.
Implementation Method 1
the first light transmitting member can be used to refract the third testing light, and the third testing light is adjusted to focus at the first focus position
Data Source
AI summary
Herein disclosed is an optoelectronic unit measuring device comprising an objective lens, an imaging lens, a photographing lens, and a focus adjustment module disposed in a first light path. The objective lens receives a first testing light and converts the first testing into a second testing light. The imaging lens receives the second testing light and converts the second testing light into a third testing light. The photographing lens receives the third testing light and measures beam characteristic. The focus adjustment module selectively provides a first light transmitting member in the first light path, and adjusts the third testing light to focus at a first focus position or a second focus position. Wherein the focus adjustment module comprises a first carrier plate having a first area with the first light transmitting member, and moves the first carrier plate to selectively align the first area with the first light path.
