The triplet apochromat lens has revolutionized immersive technology such as VR (virtual reality) headsets, with its integration into these devices proving key to minimizing chromatic aberration and ensuring unparalleled visual clarity and realism.
Triplet apochromat lenses in VR headsets typically feature an aspheric convex lens, double convex lenses, and a double concave lens. This robust lens combination ensures an improved imaging effect while allowing for a smaller-sized device.
This type of lens is used across a wide range of application areas, with its sharp, clear images, good contrast, and excellent color reproduction, making it a popular choice in biology, medicine, photography, astronomy, and many other fields.
The triplet apochromat lens is designed to minimize chromatic aberration, helping ensure that devices benefit from high-quality, practically chromatic aberration-free images.
Its design is slightly more complex than a number of other commonly-used lenses, but its advantages in terms of performance and versatility make the triplet apochromat lens a cost-effective, stable, and unique component.
Project Overview
A triplet apochromat lens can help ensure that VR headsets offer optimal image quality, significantly reduced chromatic aberration, and ensure the delivery of clearer, more realistic visuals in virtual environments.
In the example VR headset discussed here (manufactured by Avantier Inc.), this high-performance lens helped make the headset a market leader, delivering unmatched immersive experiences to users and ensuring visual enjoyment across various applications.
With this combination of a market-leading VR headset and premium lens technology, users can engage and immerse themselves in gaming, movie-watching, or virtual tourism, all as if they were truly there in the virtual world.
Design and Manufacture
Unlike conventional spherical cemented lenses, the triplet apochromat lens in the example presented here incorporates both spherical and aspherical surfaces (Figure 1).
The device’s optical components consist of a spherical surface (S1), an aspherical surface (S2), and a further spherical surface (S3). The edges of the aspherical surface (S2) are designed according to precise specifications, resulting in stringent requirements in the manufacturing process.
These aspherical surfaces (S2) require high-precision surface shapes and seamless cementation. In order to meet these manufacturing demands and ensure product quality, Avantier has implemented an integrated molding and bonding process.

All of the lens’s optical elements - the convex lens, double concave lens, and double convex lenses - are essential to the proper operation of the device.
The unique design of the edges of aspherical surfaces (S2) poses challenges throughout the manufacturing process because these surfaces must be fully optimized in terms of their shape and quality.
A series of precision manufacturing processes have been employed in order to ensure optimal optical performance. Avantier leverages a combination of extremely precise CNC machining equipment and advanced aspherical polishing equipment such as the Satisloh SPS-200.
Avantier’s CNC machines are able to accurately cut, shape, and process the optical elements’ shapes and sizes to meet the lenses’ exacting design specifications.
This precision machining ensures that the optical components’ geometric shapes meet all requirements while consistently exceeding the required optical performance.
Aspherical optical elements have complex curvatures and curves, making them much harder to process than conventional spherical elements. Aspherical polishing equipment such as the Satisloh SPS-200 has been designed with these challenges in mind, allowing the effective processing of aspherical optical surfaces.
The Satisloh SPS-200 employs advanced polishing technology to perform high-precision processing and polishing on optical surfaces, ensuring optimal surface quality of polished optical components.
This powerful instrument is able to minimize scattering and losses in optical systems and eliminate defects on optical surfaces, reliably enhancing both optical performance and imaging quality.
Aspherical surfaces have high shape and surface accuracy requirements, and these must be fitted together without any gaps between them. Avantier’s integrated molding and bonding manufacturing process addresses this challenge, ensuring excellent optical performance and meeting all design requirements.
