Design & Manufacturer

Different from traditional spherical cemented lenses, this triplet apochromat lens incorporates both spherical and aspherical surfaces, as shown in the diagram. The optical components of the device consist of a spherical surface S1, S2 being aspherical, and S3 being spherical. The edges of the aspherical surfaces S2 are specially designed, with strict requirements on the manufacturing process. Considering that S2 are two surfaces with high demands for aspherical surfaces, as they require high-precision surface shapes and seamless cementation, we have adopted an integrated molding and bonding process to ensure product quality.

The optical elements  convex lens, a double concave lens, and double convex lenses are critical components of the device. The unique design of the edges of aspherical surfaces S2 demands strict requirements on the manufacturing process in terms of shape and surface quality. To ensure optimal optical performance, a series of precision manufacturing processes have been employed. Avantier has CNC machining equipment with higher precision and higher aspherical polishing equipment such as the Satisloh SPS-200. Firstly, the CNC machines owned by Avantier can cut, shape, and process the optical elements’ shapes and sizes more accurately according to the design specifications. This precision machining ensures that the geometric shapes of the optical components meet the requirements and exceed the expected optical performance. Secondly, aspherical polishing equipment such as the Satisloh SPS-200 is specifically designed for processing aspherical optical surfaces. Aspherical optical elements have complex curvatures and curves, making them more difficult to process than spherical elements. The Satisloh SPS-200 utilizes advanced polishing technology to achieve high-precision processing and polishing on optical surfaces, ensuring that the surface quality of optical components reaches optimal levels. This equipment can eliminate defects on optical surfaces and minimize scattering and losses in optical systems, thereby improving optical performance and imaging quality.

In the optical design, the aspherical surfaces impose high requirements on their shape and surface accuracy. Furthermore, ensuring a perfect fit without any minute gaps between them adds another challenge. To address this complexity, we have introduced an integrated molding and bonding manufacturing process.
