Optical lenses are fundamental components used to focus, collimate, diverge, or image light in optical systems. By precisely controlling the path of light through refraction, lenses enable accurate image formation, beam shaping, and optical measurement across a wide range of industries.
Shape Optics manufactures a comprehensive range of precision optical lenses, including single lenses and achromatic doublet lenses, designed to meet demanding performance requirements in imaging, laser, medical, and industrial applications. From prototyping to volume production, lenses are produced with tight tolerances, excellent surface quality, and customizable optical coatings.
Functions of Optical Lenses
Optical lenses perform several critical functions within optical systems:
- Imaging – Forming clear, high-resolution images in cameras, microscopes, and sensors
- Focusing & Collimation – Converging or parallelizing light beams in laser and optical instruments
- Aberration Control – Achromatic doublet lenses reduce chromatic aberration for improved color accuracy
- Measurement & Detection – Supporting accurate optical measurement and inspection systems
- Beam Shaping – Modifying beam size and divergence in laser processing and illumination systems
