Q: What are the disadvantages of using aspheric lenses? A: Aspheric lenses have some limitations, including a relatively smaller light area, potentially causing slight blurring of objects viewed through the lens’s edge when the eye rotates. Additionally, due to the natural spherical shape of the eyeball, wearers may need time to adapt as objects viewed […]
Q: How do aspheric lenses perform at high precisions, and what advantage do they have over traditional spherical lenses in this regard? A: Even at high precisions (+7.00D-22.00D), aspheric lenses maintain clear vision, showcasing a high luminosity performance. Traditional spherical lenses may struggle to eliminate aberrations at such high precisions, making aspheric designs a preferred […]
Q: What benefits do aspheric lenses offer in terms of peripheral vision and aesthetics? A: Aspheric lenses provide better peripheral vision compared to spherical lenses, enhancing overall visual comfort and safety. They can be designed with flatter base arcs, resulting in a thinner and slimmer profile, improving the appearance of the wearer and reducing peripheral […]
Q: How do aspheric lenses address optical aberrations, specifically spherical aberration? A: Aspheric lenses are designed to reduce aberrations, especially spherical aberration, which causes blurriness and reduced image quality. By focusing light to a single point regardless of entry angle, aspheric lenses overcome this distortion, resulting in clearer and sharper vision. Back to top page
Q: What are the advantages of using aspheric lenses over traditional spherical lenses? A: Aspheric lenses offer several advantages, including optical benefits such as the reduction of aberrations, particularly spherical aberration. They focus light to a single point, enhancing vision clarity and sharpness. Aspheric lenses also provide improved peripheral vision, have a thinner and slimmer […]
Q: What challenges arise when increasing the diameter of optics, such as aspheric lenses? A: The CNC polishing equipment must have a broad range of motion and the lens’s weight becomes an issue. Measuring large aspheres is challenging, especially if the sagittal height hinders a tactile profilometer’s stylus. Using a larger stylus may compromise accuracy. […]
Q: What benefits do Polarization Directed Lenses offer? A: These lenses, serving as a thin film equivalent of a geometric optic, boast a much smaller volume compared to an equivalent spherical optic, leading to substantial reductions in weight and thickness. The technology employed in their creation is also adept at producing gratings and other polarization […]
Q: What are the disadvantages of Polarization Directed Lenses? A: For optimal efficiency, these lenses necessitate incoming light to be circularly polarized, demanding careful setup and potentially additional polarization optics in the optical design. Additionally, as these lenses function as gratings, they exhibit significant chromatic aberration when employed with broadband illumination. It is advisable to […]
