Fused Silica vs. BK7 for High-Power Laser Optics
Choosing between fused silica and BK7 is a critical decision when purchasing high-power laser optics. The wrong substrate can increase absorption, cause thermal lensing, reduce beam quality, shorten coating life, and create unexpected replacement costs. As an optical spherical lens manufacturer, Sunday Optics helps laser users evaluate substrate material, wavelength, pulse format, coating

Meniscus Lens vs. Plano-Convex Lens: Which Performs Better?
Choosing between a meniscus lens and a plano-convex lens is not simply a matter of selecting the stronger Spherical Lens. Engineers usually compare the meniscus lens vs. plano-convex lens for a specific application, such as finding the best lens for a collimated laser beam or identifying a reliable custom optical spherical lens manufacturer. The decision depends on spherical aberration, focal

How Does Lens Orientation Affect Spherical Aberration?
Spherical Lens orientation changes where marginal rays meet the optical axis. For a plano-convex lens focusing a distant, collimated beam, placing the curved surface toward the incoming beam usually reduces spherical aberration compared with reversing the lens. This practical rule is often described as the best orientation for a plano-convex lens, but the correct choice also depends on lens

Why Contaminated Laser Lenses Fail at High Power
A contaminated laser lens can appear harmless at low power, yet fail within seconds when the beam reaches a high-power operating condition. The reason is localized absorption: dust, oil, fingerprints, process fumes, and microscopic moisture absorb part of the laser energy and convert it into heat. That heat creates a thermal lens, coating stress, surface deformation, and eventually a

Which Spherical Lens Shape Is Best for Your Optical System?
A Spherical Lens selection can determine whether an imaging or laser assembly reaches its target resolution, transmission, and working distance. This guide explains the best spherical lens shape for optical system design, how to choose spherical lens curvature, and when to work with a custom spherical lens manufacturer. It compares the plano-convex lens, biconvex lens, and other forms using

How Ball Lenses Support Compact Optical Measurement Systems
A compact optical measurement system can fail even when its sensor, light source, and software are correctly specified. The underlying problem is often the optical interface: insufficient working distance, poor coupling efficiency, excessive package size, or alignment sensitivity between the emitter, target, and detector. In conventional lens assemblies, these issues may force engineers to add

What is an Aspheric lens? How to define aspherical lens? The ordinary lenses we usually see have two spherical surfaces — just like a piece cut from a perfect sphere, with the same degree of curvature from the center to the edge. An aspherical surface, however, means: the surface is not a perfect sphere, and its degree of curvature gradually ch

Applications of Cylindrical Lenses
Astigmatism is an optical aberration that can cause images to appear distorted or blurred. It occurs when light rays entering the eye or an optical system are not focused equally in all directions, resulting in different focal points in different planes.
