01 / OVERVIEW

Spherical lenses for precision optical systems

A spherical lens is an optical component with one or more spherical surfaces designed to focus, collimate, or diverge light within an optical system. Spherical lenses are available in positive and negative configurations, including plano-convex, plano-concave, bi-convex, bi-concave, meniscus, and ball lenses, providing versatile solutions for imaging, laser, sensing, and illumination applications.

Strahl Optics applies optical fabrication processes to achieve accurate spherical geometry and consistent surface quality across different lens forms. Curvature and dimensional accuracy are evaluated during fabrication to maintain the intended optical performance.
