Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid immersion lens holders face difficulties in achieving close contact with observation objects, which hinders optical coupling due to fabrication errors and restricted movement of the lens.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the solid immersion lens is held in a fixed state by the lens holding unit, then the lens position is stable, but the lens cannot freely move to contact the observation object, preventing favorable close contact
Solution Approach 1:
The lens holding unit is designed to hold the solid immersion lens in an unfixed state, allowing it to move freely in the vertical direction. This dynamic holding approach enables the lens to automatically contact and adhere to the observation object under vibration, resolving the contradiction between position stability and movement freedom.
Solution Approach 2:
A vibration generator unit is introduced to apply vertical vibration to the holder main body, which transmits to the lens holding unit and solid immersion lens. The vibration facilitates the lens to adhere tightly to the observation object surface, enabling favorable close contact while maintaining overall system stability.
2Ease of operation
If the solid immersion lens is made to freely move with respect to the lens holding unit, then the lens can easily contact the observation object, but fabrication errors may prevent favorable contact
Solution Approach 1:
The vibration generator unit compensates for fabrication errors in the lens holding unit by applying vertical vibration that enables the solid immersion lens to adhere tightly to the observation object surface. This vibration mechanism overcomes positional deviations caused by manufacturing inaccuracies.
Solution Approach 2:
The system changes the operational state of the lens holding unit from a fixed rigid structure to a dynamic structure that accepts vertical vibration. This parameter change allows the system to tolerate fabrication errors while achieving favorable lens-to-object contact.
3Reliability
If the holder main body is caused to vibrate, then the solid immersion lens adheres tightly to the observation object surface, but the device complexity increases
Solution Approach 1:
A vibration generator unit is added to the holder main body to produce vertical vibration. This vibration mechanism, while adding device complexity, ensures reliable and favorable close contact between the solid immersion lens and observation object, which is essential for optical coupling.
Solution Approach 2:
The vibration generator unit serves multiple functions: it facilitates lens adhesion to the observation object, compensates for fabrication errors, and ensures consistent optical coupling. This multi-functionality justifies the added device complexity.
Applied Scientific Principles

Function Achieved in This Case
Improves close contact and achieves appropriate optical coupling between the solid immersion lens and the observation object, enhancing observation accuracy.
Implementation Method 1
when the holder main body is caused to vibrate by the vibration generator unit, the vibration is transmitted from the lens holding unit to the solid immersion lens, which causes the solid immersion lens to vibrate to adhere tightly along the surface of the observation object

AI summary
A solid immersion lens holder 200 includes a holder main body 8 having a lens holding unit 60 that holds a solid immersion lens 6, and an objective lens socket 9 for attaching the holder main body 8 to a front end of an objective lens 21. The solid immersion lens 6 is held in a state of being unfixed to be free with respect to the lens holding unit 60. A vibration generator unit 120 that causes the holder main body 8 to vibrate is attached to the objective lens socket 9. The vibration generator unit 120 has a vibrating motor 140 held by a motor holding member 130, and a weight 142 structured to be eccentric by weight is attached to an output shaft 141 of the vibrating motor 140. A vibration generated in the vibration generator unit 120 is transmitted to the solid immersion lens 6 via the objective lens socket 9 and the holder main body 8. Thereby, achieving the solid immersion lens holder capable of improving the close contact between the solid immersion lens and an observation object.
