In the assembly of optical lenses, ensuring centering accuracy is a critical step after aligning the optical lenses with the lens barrel.Centering accuracy is a key parameter that characterizes the co...

In the field of laser applications, two essential concepts often arise: collimation and focusing. These terms are frequently encountered, yet they can be confusing for those new to laser technology. F...

Telecentric lenses are renowned for their unique capabilities, particularly in applications requiring precise measurements and stable imaging. These lenses offer several key advantages that set them a...

The classical Cassegrain system is composed of two reflective mirrors: a concave parabolic primary mirror and a convex hyperbolic secondary mirror. The focus of the parabolic mirror coincides with the...

Dove Prisms, also known as Dove Prisms, are a distinctive type of optical element renowned for their ability to rotate objects. This unique property has made them indispensable across a wide range of ...

Broadly speaking, any optical surface that is neither spherical nor planar is referred to as an aspheric surface. A spherical lens has a constant curvature from the center to the edge, while an aspher...

1. Chromatic Aberration CorrectionTraditional spherical lenses, due to their spherical symmetry, exhibit varying refractive indices for different wavelengths of light, leading to chromatic aberration....

1. High ResolutionImage resolution is typically quantified using the Contrast Transfer Function (CTF), measured in line pairs per millimeter (lp/mm). Many machine vision integrators often combine nume...
