Achromatic Lens Definition

Super Achromatic Lens, 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.
