Product Introduction
1. Plano-Concave Spherical Lens
The plano-concave spherical lens is a negative focal length diverging lens commonly used in optical systems. It features one flat surface and one concave spherical surface, causing incident light to diverge. It is suitable for beam expansion, collimation, numerical aperture reduction, and optical path matching. Manufactured with high-precision optical glass grinding and polishing, this lens offers high surface accuracy, good transmittance, low stress, and stable imaging. It is ideal for laser, imaging, sensing, and scientific research applications.
2. Plano-Convex Spherical Lens
The plano-convex spherical lens is the most commonly used positive focal length focusing lens in optical systems. With one flat surface and one convex spherical surface, it efficiently focuses parallel light to a point or collimates a point source into parallel light. It is a core component for focusing, collimating, imaging, and coupling optical paths. Featuring a simple structure, easy assembly, high stability, and cost-effectiveness, it is widely used in laser focusing, fiber coupling, machine vision, imaging lenses, projection optics, medical diagnostics, and scientific research.
3. Aspheric Lens
The aspheric lens is a high-end optical component with a continuously optimized surface profile. Through aspheric curvature design, it precisely corrects various aberrations such as spherical aberration, coma, and distortion, significantly improving imaging quality and light concentration efficiency. Compared with traditional spherical lenses, a single aspheric lens can replace multiple spherical lens combinations, enabling system miniaturization, lightweight design, and simplified assembly. Widely used in high-end optical systems such as laser focusing and collimation, high-resolution imaging, automotive optics, machine vision, AR/VR, medical diagnostics, and fiber optic communications, it is the preferred choice for optical paths requiring high resolution, high brightness, and compact size.
