As one of the world’s foremost producers of high performance IR lenses, we carry a wide selection of SWIR lenses, LWIR lenses, MWIR lenses, and NIR lenses. These lenses are ideal for use in the infrared region, with applications including industry, medicine, scientific research, and defense.

Aspheric lenses offer significant advantages over traditional spherical lenses due to their unique shape and optical properties. Let’s delve into these advantages and also consider some of their disadvantages, as discussed in the provided articles.

Crystalline materials are generally expensive. In addition to these crystalline materials, infrared glass can also be used as a material for the manufacture of infrared objectives. The most common infrared glass is chalcogenide glass, chalcogenide glass is S, Se, and Te As the main components, combined with AS, Ge, P, Sb, Al, Si, and other elements to form a glassy substance, different chalcogenide glass brands have differences optical characteristics, the glass material selection should be based on the need to the atmospheric window.

Common used infrared crystal materials include germanium, silicon, zinc sulfide, and zinc selenide, these materials are the most frequently used in the design of infrared objectives, these materials have a high refractive index, which is conducive to aberration correction. In addition, CaF2, sapphire, CdTe, and other materials will also be used, and the frequency of use is relatively lower. Infrared quartz can also be used in the design of infrared objectives but is limited to the near-infrared wavelength. Their optical parameters are as follows:

At Avantier, we manufacture a wide variety of aspheric lenses for applications from smartphones to lasers and fiber optics, from research and industry to medicine. If you have more questions about aspheric lenses, don’t hesitate to contact us. Our experienced optical designers are always available to discuss a custom order.

Fortunately, IR cameras serve as effective tools for detecting this form of light. Infrared cameras necessitate specialized components including a custom lens, infrared filters, and sensors to capture IR light.

An infrared objective lens is an objective lens suitable for the infrared wavelength. The infrared wavelength refers to the three wavelengths of 1-3um, 3-5um and 8-14um, also known as the three atmospheric windows. Infrared objective lens has been widely used in temperature measurement, medical diagnosis, security supervision, forest fire prevention, agricultural planting and military reconnaissance, tracking, guidance and other fields, is a very important lens type.

According to the different wavelengths used, the infrared objective lenses on the market are generally classified by wavelength, which can be divided into short-wave infrared lenses, medium-wave infrared lenses and long-wave infrared lenses. The objective lens of different wavelength is suitable for different atmospheric Windows, and the user should choose the objective lens according to his own application and use environment.

An infrared lens operates by capturing the infrared light present in the environment and redirects it towards the camera sensor. This process aids in the creation of clear thermal images. IR lenses designed for use in infrared cameras are capable of capturing imperceptible heat or IR radiation within extended wavelength ranges, typically spanning from 700 to 900 nm or beyond.

The human eye, akin to an optical device, possesses a sensory component known as the retina. Similar to conventional cameras, the eye receives and converts radiation from the visible light spectrum into images.

Chalcogenide glass has a small refractive index temperature coefficient and a low dispersion coefficient, so chalcogenide glass is usually considered in achromatic and non-thermal optical designs. In addition, the price of chalcogenide glass is generally lower, which is conducive to the cost control of the objective lens.

We offer a wide selection of in-stock IR Lenses to meet your needs, including SWIR, LWIR, MWIR, and NIR lenses. These in-stock IR lenses excel in the realm of infrared applications and are invaluable in various industries. Avantier offers in-stock IR Lenses for sale, and also specializes in designing and manufacturing custom IR Lenses.

The biggest difference between the normal visible light objective and the infrared objective is that the material used is different. In general, the visible light wavelength uses normal optical glass and some crystal materials. Normal glass materials contain hydroxyl, which has a large absorption in the infrared wavelength, and can usually only be used in the near UV-visible light-near-infrared wavelength, which can not cover most of the infrared wavelength.

Optical Advantages: Aspheric lenses are designed to reduce aberrations, especially spherical aberration. Spherical aberration is a distortion that occurs when light passes through a spherical surface, causing blurriness and reduced image quality. These lenses focus light to a single point, regardless of the entry angle, resulting in clearer and sharper vision.

In summary, the future of infrared lenses is characterized by continuous advancements in performance, miniaturization, multi-spectral imaging capabilities, and expansion into new IR applications. These trends will further enhance our ability to harness the power of infrared radiation for a wide range of scientific, medical, industrial, and security purposes.

In summary, the significance and advantages of aspheric lenses are primarily related to their ability to correct optical aberrations, provide clearer and sharper vision, and offer improved peripheral vision. They also come with aesthetic benefits such as a slimmer profile and better appearance. However, they have some limitations, including a smaller light area and potential adjustments needed for individuals used to spherical lenses. Advances in manufacturing have made aspheric lenses more affordable and versatile, allowing them to replace multiple spherical lenses in various applications, resulting in cost-effective and high-performance optical systems.

Our customized IR lenses stand as a testament to our commitment to excellence, offering cost effective and unparalleled performance tailored to your specific needs.

A light field is called coherent when there is a fixed phase relationship between the electric field values at different locations or at different times.

Because infrared light is much longer than visible light, the detector pixel size used is relatively large, and the infrared objective lens generally does not have high requirements for the line frequency, and the design of the infrared objective lens is relatively simple. However, infrared objective lenses also have some characteristics and difficulties in their own design, such as fewer options of materials, design for different types of sensor , stray light processing problems.
