Lens TRIZ Cases
- Imaging Lens Assembly Aberration Correction via Curvature Ratios
Aspheric lens configuration corrects spherical aberration and astigmatism in compact imaging systems.
- Four-Element Optical Imaging Lens Compact Design
A four-element optical imaging lens uses controlled surface shapes to shorten total length while maintaining high optical performance.
- Zoom Lens Optical Path Bending Member Positioning
A zoom lens configuration positions an optical-path bending member near the image face to shorten the optical axis length.
- Freeform Lens Rectangular Image Sensor Utilization
An asymmetric freeform lens transforms circular fisheye images into rectangular shapes, eliminating unused sensor area.
- Five-Element Plastic Lens System Aberration Control
A five-element plastic lens system uses specific refractive power distribution and aspheric surfaces to correct optical aberrations.
- Micro Zoom Lens Aberration Correction via Group Segmentation
Segmented lens groups with negative and positive refractive powers resolve the contradiction between miniaturization and aberration control in compact cameras.
- Five-Element Optical Imaging Lens Compact Design
A five-element optical imaging lens uses alternating refractive powers to reduce total track length.
