2.10: Designing an Achromatic Doublet - Physics LibreTexts
网页An achromatic doublet is typically made of a positive crown glass lens whose power is positive but which decreases with increasing wavelength (i.e. toward the red), cemented to a weaker flint glass lens whose power is negative and also decreases (in magnitude) with increasing wavelength.
Achromatic Optics – lens doublets, apochromats, achromatism, …
网页These achromatic doublet lenses are available in focal lengths up to 500mm and are ideal in imaging applications, laser collimation, and as objective lenses in telescopes and other instruments. Custom achromatic lenses are available upon enquiry including triplet lenses and additional coatings.
24.3: Lenses - Physics LibreTexts
网页achromatic doublet: A type of lens made up of two simple lenses paired together designed so that the chromatic aberration of each lens partially offsets the other; in this way light in a range of wavelengths may be brought to the same focus.
Achromatic Doublet - optics-online.com
网页Achromatic doublet lenses ("achromat") are designed to eliminate chromatic and spherical aberrations inherent in singlet lenses. When used on-axis, an achromatic lens focuses an parallel input beam to a perfect "point", limited only by the effects of diffraction.
Achromatic Lenses (Achromatic Doublets) — Firebird Optics
网页Achromatic doublet lenses are focusing components used in laboratory and medical devices to reduce chromatic aberrations from broadband light sources. A doublet is typically composed of two individual lenses with varying levels of dispersion, fused together and shaped so that the chromatic aberration of one is counteracted by another.
Combinations of Achromatic Doublets (Chapter 8) - Introduction to Lens ...
网页The achromatic doublet is a fundamental building block in lens design because it is corrected for chromatic aberrations, and can also be corrected for spherical aberration and coma aberration. The early lens designers explored all combinations of …
Understanding Lenses: Aplanats and Achromats - Photonics
网页Depending on the application, doublet and triplet achromatic lens designs can be optimized for broad wavelength regions (usually in the visible from 400 to 700 nm) or for two distinct wavelengths (such as 1064 or 532 nm).
Cemented Achromatic Doublets - Thorlabs
网页Thorlabs' cemented achromatic doublet lenses are available with antireflection coatings for the 400 - 700 nm, 400 - 1100 nm, 650 - 1050 nm, or 1050 - 1700 nm wavelength range. They come in mounted and unmounted options, as well as matched pairs and kits.
Achromatic Lenses - Thorlabs
网页Our achromatic lenses are offered mounted, unmounted, and in matched pairs. We offer achromatic doublets, cylindrical achromatic doublets, and air-spaced achromatic doublets, as well as achromatic triplets that allow for maximum aberration control.
Lens Tutorial - Thorlabs
网页2024年7月5日 · The multi-element design of achromatic lenses reduces these aberrations and leads to significantly increased image quality and tighter focusing of monochromatic light. For example, Figure 2 compares the performance of a plano-convex lens and an achromatic doublet in focusing a monochromatic beam.
