Positive Meniscus Lenses
Overview
- Lens with one convex and one concave surface
- Designed to converge light while minimizing spherical aberration
Key Features
- Improved Aberration Control
- Better focusing than simple convex lenses
- Higher numerical aperture capability
- Design & Construction
- Convex curvature dominates
- Optimized for reducing spherical aberration
- Wavelength Options
- UV, Visible, NIR
-
Applications
- High-performance imaging
- Laser focusing
- Optical systems requiring better correction
Why Choose Positive Meniscus
- Better performance than bi-convex in many systems
- Reduced aberrations
