Achromatic Spherical Lenses, Cemented Lenses, Bonded Lenses, Doublet, Triplet

With over a decade of production experience, we have significantly improved our achromatic spherical and cylindrical lenses manufacturing. From the beginning stage during evaluation, we help customers with material selection for cemented elements, thoroughly analyze potential production risks, and assess the cementing precision definition of the prints.

We are able to provide flint and crown glasses bonding solution with meniscus elements edged on optical edging device with precision wedge control. Our production team is also specialized in doublet and triplet fabrication with calcium fluoride (CaF2) lenses, which require special adhesive treatment for extended durability.

Our bonding operators carefully pair the individual lenses regarding radius (power), center thickness (CT) to ensure adhesive thickness and accurate CT control for high-precision requirement. We utilize UV curing / cold bonding techniques on different glass materials in order to enable operators eliminating center deviation on upgraded centering station. For doublet and triplet diameters exceed one inch, 0.6 arc min to 0.8 arc min is our standard wedge control precision.

We can precisely control the center thickness of doublets to within +/-0.04mm, triplet within +/-0.05mm for airspace sensitive design. A design that includes OHARA and SCHOTT glasses typically take longer due to material supplier’s lead time (>6 weeks); our engineering team can speed up the procurement process by helping you select compatible materials from our glass inventory database and dramatically reduce lead time to within one week to have the substrates ready.

Definition of Achromatic Lens

Achromatic lenses are a combination of a positive low refractive index (corona crown ) and negative high refractive index (flint). Compared with monolithic singlet lens the doublet design can provide users with additional design freedom and further optimize the performance of the lens. Therefore, the advantages of achromatic lenses are more significant than those of single lenses with equal diameter and focal length.

Types of Achromatic Lens

Achromatic lenses have various kinds of configurations, of which, the most common ones are positive achromatic lenses, negative achromatic lenses, three - phase achromatic lenses and aspheric achromatic lenses. It is important to note that the achromatic lens can be a doublet or triplet (three components), and the number of elements is independent of the amount of light that is corrected.  In other words, the doublet or triplet achromatic lens can be used to correct both red and blue light in the visible range.

The non-spherical achromatic lens is a cost-effective lens with excellent chromatic aberration and spherical aberration correction function. It meets the exacting imaging requirements of optical and visual systems in an affordable way. With the help of the aspheric achromatic lens, the relay system, the condenser system, the high numerical aperture imaging system can be improved. Generally speaking, the resolution of the aspheric achromatic lens is better than the achromatic lens.

Application of Achromatic Lens

Achromatic lens is used to minimize or eliminate chromatic aberration. The design of achromatic also helps minimize spherical aberrations. The achromatic lenses originally designed for telescopes can now be found in various optical instruments, including cameras. Achromatic lenses are ideal for a range of applications, including fluorescence microscopes, image relays, detection applications or spectral meters. The achromatic lens, which is designed by cementing two components together or installing two components in one cell can produce a smaller beam spot size than a comparable single lens.
