What are Positive Meniscus Lenses?
Positive meniscus lenses are designed to minimize spherical aberration. They have one convex and one concave surface. When used in combination with another lens, a positive meniscus lens will shorten the focal length and increase the NA of the system.
What is the application of Positive Meniscus Lenses?
1. Eyewear: especially for correcting farsightedness and nearsightedness, providing a more comfortable visual experience.
2. Laser system: used to adjust the focusing state of the laser beam to improve the accuracy and efficiency of the laser.
3. Optical instruments: used to improve optical paths and imaging effects in a variety of optical measuring and analysing instruments.
4. Spectroscopy: the application of meniscus lenses in spectroscopy is mainly reflected in their ability to provide higher performance, especially in reducing spherical aberration and improving imaging quality.
5. Thermal imaging: the use of meniscus lenses in thermal imaging also benefits from their ability to reduce spherical aberration, thus providing sharper and more accurate imaging.
What is a Positive Meniscus Lens use for?
Positive meniscus (convex-concave) lenses are designed to minimize spherical aberration. When used in combination with another lens, a positive meniscus lens will shorten the focal length and increase the numerical aperture (NA) of the system without introducing significant spherical aberration.
