Inverted Microscope Independent Optical Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inverted microscopes lack flexibility in arranging and replacing optical devices between the objective lens and imaging lens, limiting system expandability and optical performance.
Innovation Solution
The design includes a microscope main body with installation units that allow optical devices to be fixed independently, featuring abutting reference surfaces shifted perpendicular to the optical axis, enabling easy attachment and detachment of optical devices without altering the microscope's configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical devices are directly stacked and fixed in conventional inverted microscopes, then the optical path can be branched, but the optical devices cannot be easily detached or replaced
Solution Approach 1:
The optical device mounting structure is divided into multiple independent installation units, each capable of holding one optical device. Each installation unit has its own abutting reference surface and mounting mechanism, allowing individual optical devices to be attached or detached without affecting others. This segmentation enables flexible system configuration while maintaining easy access to each component.
Solution Approach 2:
The installation units are designed with standardized abutting reference surfaces that can accommodate different types of optical devices. The same installation unit structure can hold various optical components (filters, mirrors, beamsplitters) by simply changing the device while keeping the mounting structure unchanged, providing universal compatibility.
2Adaptability or versatility
If multiple optical devices are stacked with fixed positions, then the optical system can be configured, but the installation positions cannot be easily changed
Solution Approach 1:
The mounting structure transitions from fixed rigid positions to dynamic adjustable positions. Each installation unit can be independently positioned and adjusted within the optical path, allowing the optical devices to be reconfigured at different locations. This dynamic capability enables position flexibility without requiring complex reconfiguration of the entire mounting structure.
Solution Approach 2:
The installation units are arranged in multiple dimensions (vertical stacking and horizontal positioning), creating a three-dimensional mounting architecture. This multi-dimensional arrangement allows optical devices to be positioned at various locations and orientations, providing position flexibility while maintaining a relatively simple overall structure through spatial distribution.
3Reliability
If optical devices are installed in fixed positions between objective lens and imaging lens, then optical path branching is achieved, but optical performance cannot be optimized according to device positions
Solution Approach 1:
The mounting structure allows for adjustable parameters including the position, orientation, and spacing of optical devices within the optical path. By changing these parameters, the optical performance can be optimized for different applications while maintaining the ability to reconfigure the device arrangement. The abutting reference surfaces provide precise positional control for optimal optical alignment.
