Component Specifications

Definition
A lens element is a fundamental optical component designed to manipulate light through refraction, typically made from transparent materials with precise curvature. In precision optical lens arrays, multiple lens elements are arranged to correct aberrations, control focal length, and achieve specific optical performance metrics. These elements are manufactured to sub-micron tolerances for applications requiring high resolution and minimal distortion.
Working Principle
Operates on the principle of refraction, where light bends as it passes through materials with different refractive indices. The curvature of the lens surfaces determines how light rays converge or diverge, enabling functions like focusing, collimating, or imaging in optical systems.
Materials
Optical glass (e.g., BK7, Fused Silica), optical plastics (e.g., PMMA, Polycarbonate), or crystals (e.g., Sapphire). Materials are selected based on refractive index, dispersion, transmission range, and environmental stability.
Technical Parameters
  • Coating AR, HR, or custom
  • Diameter 5-100 mm
  • Centration <1 arcmin
  • Focal Length 10-500 mm
  • Clear Aperture >90% of diameter

Frequently Asked Questions

What is the difference between a lens element and a complete lens assembly?

A lens element is a single optical component, while a lens assembly consists of multiple elements combined to achieve specific optical performance, such as reduced aberrations or variable focus.

How are lens elements tested for quality?

Testing includes interferometry for surface accuracy, spectrophotometry for transmission, and environmental tests for durability under temperature and humidity variations.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
