It has the advantages of low-light and thermal imaging at the same time, and there are a variety of observation modes to choose from, which can better meet the observation needs of different scenes and different people; 2. The observed information is more abundant, the details are more perfect, the scene is easier to understand, and the effective detection and recognition distance is longer; 3. The observed target is more obvious, which is beneficial to detect the target faster and more accurately under the background of concealed camouflage. The use of image fusion color night vision mode is particularly prominent; 4. The observed image is more natural and more in line with the habits of the human eye, which can significantly improve the target recognition performance of the human eye and reduce fatigue; 5. To meet the needs of all-weather combat, it can be observed and used in the dark, in a completely dark and closed environment and in bad weather conditions; 6. Small size, light weight, comfortable and convenient to use, long continuous working time and good environmental adaptability.

A biconvex lens means that both surfaces of the lens are convex. Its focal length is positive and mainly for the function of focusing. It is commonly used in imaging relay system and object imaging at finite conjugate distance. The smaller the conjugate ratio is, the smaller the aberration will be. Oplens can not only customize the common plano-convex lens of N-BK7 or fused quartz, but also customize the biconvex lens of any glass material. You are welcome to contact us for customized biconvex lenses.

Because of this, Oplens set up its own assembly department in 2021, which not only improves our production line but also can better meet the needs of customers for lens assembly. If you don’t have such a lens assembly environment or inspection conditions, we are capable to help you in this respect.   What Processes are Involved in Optical Assembly Manufacturing? Optical assembly processes may include mounting, alignment, precise optical pathway placement, beam manipulation, focusing, optical bonding, and sonic welding techniques. Typical Optical Component Assembly Work Includes: Bonding glasses & filters into wheels Laminating glasses & filters Product labelling & identification Gluing glass to glass components Mounting in screw mounts and holders Gluing glass to metal assemblies Press fitting glass lenses into housings. To outsource your lens assembly, contact our sales team who will advise you on your next move.

An achromatic lens is a lens designed to minimize chromatic aberration and spherical aberration. Two-plate achromatic lens is one of the simplest achromatic lenses, which can be divided into two types: double agglutination and double dissociation. 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. 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.

The biconcave lens, also named double concave lens, is usually made of flint glass and used for beam divergence. It’s focal length is negative but the parallel incident ray diverges outward. The two sides of the biconcave lens curvature radius can be equal or not. Combined with plano-convex lens, it is generally used in beam expanders, projection optical systems and optical viewers, etc. Oplens can not only customize the common plano-concave lens of N-BK7 or fused quartz, but also customize the biconcave lens of any glass material. You are welcome to contact us for customized biconcave lenses.

A plano-concave lens is a lens that has a flat surface on one side and a concave surface on the other side. The focal length of a plane-concave lens is negative, allowing the beam to diverge.  Therefore, it can be used in optical system for beam expansion, light projection or to increase focal length.   Oplens can not only customize the plano-concave lens with common materials of N-BK7 (Shott) and fused silica, but also customize the plano-concave lens of any glass material.     You are welcome to contact us for customized plano-concave lenses.
