Transmitted Light Observation Apparatus for Optical Material Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying and demonstrating optical materials fail to allow customers to easily observe transmitted light, making it difficult to judge the performance of these materials.
Innovation Solution
A transmitted light observation apparatus comprising a light emitting section, a holding section for test materials with different transmittances, and a reflecting portion that reflects and makes visible the light paths through these materials, using light sources and materials that scatter specific wavelengths to highlight differences in optical performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If demonstration lenses are colored or decorated with patterns to attract customers, then the visual appeal and sales promotion improve, but the ability to observe transmitted light and evaluate optical performance deteriorates
Solution Approach 1:
The demonstration device is divided into separate functional sections: a light source section that emits light through the lens, and an observation section with a mirror that reflects transmitted light back to the viewer. This segmentation allows the lens to maintain its decorative appearance while enabling separate evaluation of optical performance through the reflected light path
Solution Approach 2:
A mirror is introduced as an intermediary element in the observation path. The mirror reflects light that has transmitted through the lens back toward the customer, enabling them to see the optical performance without interfering with the lens's decorative appearance. This intermediary allows simultaneous achievement of visual appeal and performance evaluation
2Difficulty of detecting and measuring
If the observation apparatus uses light scattering sections to make light paths visible, then the visibility of transmitted light improves, but the device complexity increases
Solution Approach 1:
The light scattering section is integrated into the mirror assembly, allowing the same component to serve dual functions: reflecting transmitted light and making the light path visible through scattering. This self-service approach eliminates the need for separate visibility enhancement devices, thereby reducing overall device complexity while maintaining improved light path visibility

AI summary
In order to allow for easy judgment of performance of optical material having a prescribed function, provided is a transmitted light observation apparatus comprising a light emitting section that generates light including light of a prescribed wavelength; a holding section that holds a first test material and a second test material arranged respectively in optical paths of the light generated by the light emitting section; and a reflecting portion that reflects at least a portion of the light transmitted respectively through the first test material and the second test material. Transmittance of the first test material for the light of the prescribed wavelength is different from transmittance of the second test material for the light of the prescribed wavelength. The light of the prescribed wavelength has a wavelength from 380 nm to 500 nm.
