Optical Filters TRIZ Cases
- Photonic Crystal Filter for Broadband Angular Selectivity
Segmented photonic crystals with multilayer cells create continuous bandgaps from 50 nm to 100 mm, avoiding complex metallic extraordinary transmission.
- Substrate-Free MUX/DEMUX With Angled Fiber Array
Direct attachment of the optical assembly to the angled fiber array eliminates free space and aberration, reducing insertion loss.
- Integrated Spectral and Polarization Optical Filter for Image Sensors
Segmented unit filters with metal reflectors and cavities resolve scattered light interference from moisture or glass surfaces.
- Quantum Dot Color Filter Film Heat Resistance
Replacing organic pigments with quantum dots and a dianhydride-diamine modified surface layer improves heat resistance while maintaining high color saturation.
- Mosaic Scan Filter Array for High-Resolution Color Imaging
A mosaic scan filter array captures full-color information in each pixel without interpolation.
- Color Filter Substrate Light Anti-Reflection Layer Optical Loss
A color filter substrate integrates a light anti-reflection layer to boost light transmission rates across RGB units.
- Light-absorbing composition for near-infrared cut optical filters
A light-absorbing composition disperses phosphonic acid and copper ions in a curable resin to form an optical filter laminate.
- Six-Lens Optical System Aberration Correction via Segmentation
Segmenting the optical path into six elements with specific refractive powers corrects aberrations while maintaining a large aperture for compact cameras.
- Light-emitting Device Packages with Intermediate Refractive Layers
A light-emitting device package uses an intermediate layer with specific refractive indexes to manage emitted light direction and improve extraction efficiency.
- Image Sensor Micro-Lens Array LTO Layer Delamination Prevention
A Low Temperature Oxide layer prevents delamination and particle attachment in image sensors, maintaining lens integrity and yield.
- Imaging Device Polarization Alignment Wave Plate
A wave plate converts linearly polarized light into circular polarization for flexible design.
- Blue Photoresist Composition for Infrared Emission and Display
A blue photoresist composition incorporates surface-modified infrared light-emitting materials to create functional color filters.
