Optical Observation Coating for Laser Protection Without Extra Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical observation apparatuses for laser treatments require additional pivoting mechanisms and multiple dedicated elements for laser protection filters, complicating the design and increasing installation space.
Innovation Solution
Integrate a laser protection filter as a coating on a single optical element, such as the main objective, which blocks laser radiation without the need for additional elements or pivoting mechanisms, using a transmission characteristic that minimizes color distortion and interference effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate laser protection filter with a pivoting mechanism is added to the beam path, then laser radiation protection is improved, but the device complexity and installation space requirements increase
Solution Approach 1:
The patent combines the laser protection filter function with an existing optical element (beam splitter or objective lens) that is already present in the optical path. Instead of adding a separate filter component, the protective function is merged into the existing optical element by applying a coating layer, thereby eliminating the need for additional pivoting mechanisms and reducing overall device complexity
Solution Approach 2:
The existing optical element serves dual purposes: it performs its primary optical function (beam splitting or focusing) while simultaneously providing laser radiation protection through the integrated coating. This multi-functionality approach eliminates the need for dedicated protection components and simplifies the overall system architecture
2Object-affected harmful factors
If multiple dedicated laser protection filters are added for different beam paths, then comprehensive laser protection is improved, but the quantity of components and device complexity increase
Solution Approach 1:
The patent merges multiple protection functions into single optical elements. The beam splitter incorporates protection for both the left and right observation beam paths, while the objective lens provides protection for the illumination beam path, thereby reducing the total number of filter elements from three separate filters to coatings on existing components
Solution Approach 2:
Each coated optical element serves multiple protective functions simultaneously - the beam splitter protects both observation beam paths and the objective lens protects the illumination path, demonstrating multi-functionality that reduces the quantity of components needed
