Manufacturer Custom Optical Glass Positive Achromatic Lens with K9 Bak7 Quartz Materials
Achromatic doublets are one of the simplest achromatic lenses, which are cemented achromats made of two different lenses.
Oplens offer achromatic doublets, cylindrical achromatic doublets, and air-spaced achromatic doublets, as well as achromatic triplets that allow for maximum aberration control. Of course, achromatic lenses can also be composed of multiple lenses, depending on their uses.
The achromatic lens with large aperture is usually separated and assembled in the frame with excellent comprehensive performance. Achromatic lenses are widely used. A multi-lens optical system usually consists of several achromatic lenses. High quality microscopic objective lens and photographic lens are all complex lens combination systems which eliminate both achromatic and other monochromatic aberrations.
Achromatic lenses focus colors at the same point, allowing the user to focus on the image. Compared to uncorrected singlets, achromatic lenses produce sharper images, making viewing easier and perceiving more accurate.
They revolutionize the way you image. Despite the ever-increasing quality of lenses, achromatic lenses remain a staple for scientific and non-scientific optical applications.
1. What is the difference between achromatic and apochromatic?
Achromatic lenses are corrected to focus two wavelengths in the same plane - typically red (~0.590 µm) and blue (~0.495 µm). Apochromats are designed to focus three colors on the same plane - typically red (~0.620 µm), green (~0.530 µm), and blue (~0.465 µm).
2.
What is an achromatic lens used for?
Lenses that are specifically designed to control the effects of chromatic aberration or aberrations (flaws in optical lenses that bring the focus of all colors to the same point of convergence) are called achromatic lenses. It is widely known as "achromatic"
3. How do achromatic lenses work?
An achromatic lens is a combination of concave and convex glass sheets that focus different color wavelengths in light onto a single plane. Each type of glass disperses colors in a different way - putting them together balances each other out and produces a crisp image.
Oplens can produce single layer or multi-layer anti-reflective films with all kinds of coating materials on both outside surfaces. Their performance is superior to that of all single element lenses.

Oplens (brand own by SiChuan JUKA Optical Technology) is located in the city of Chengdu, China, which enjoys the reputation of the world optical processing center. Oplens has been committed to providing customers with high-precision optical system solutions over 16 years, covering the complete manufacturing process from the design, processing and assembly of various optical components and mechanics. It occupies 10,000 square meters of modernized facilities with hundreds of equipments and instruments. More importantly, Oplens owns an excellent team of more than 200 experienced engineers and workers, who provide the best products and service to their both domestic and overseas customers.
You are most welcome to experience our outstanding products and services to make your business more stably and successfully.
Besides the basic processing equipments for optical components, such as the raw material cutting machines, milling machines, fine grinders, polishers, etc., Oplens uses the single point diamond turning machine (SPDT) for highly accurate optical lenses with nanometer scale surface accuracy and dimensional accuracy.
Oplens equipped Precitech SPDT with Taylor Hobson PGI 3D profilometer. The results of the profilometer measurement system can be directly put into the diamond machine to provide positive compensation values for the machining of aspheric components. At the same time, curvature, surface flatness, roughness and other indicators can be quantified effectively and accurately.
