Avantier can provide lenses in chalcogenide material. Chalcogenide is an amorphous glass and is easier to process than traditional IR crystalline materials.

The amplitude of a periodic function, such as sine or cosine, represents the maximum distance of the graph from the midline or the average value of the function.

Vertical translationexamples

Vertical translation is the process of shifting a graph up or down on the coordinate plane without changing its shape or size. It involves adding or subtracting a constant value to the input or output of a function, resulting in the graph moving vertically without any other transformations.

Infrared light is classified as light between the wavelengths of 1 mm to about 700 nm. Infrared IR radiation can be further divided into several categories:

Chalcogenide glass is an ideal material for both high performance infrared imaging systems and high volume commercial applications. Chalcogenide glass is available in a variety of chemical composition options, but BD6, composed of arsenic and selenium (As 40 Se 60), is the best choice in terms of cost and ease of production. Chalcogenide infrared glass materials and lenses are also an excellent alternative to expensive, commodity price-driven materials such as Ge, ZnSe, and ZnS2. Chalcogenide glass primarily transmits in the MWIR and LWIR wavelength bands, making it suitable for infrared imaging applications.

An IR lens is an optical lens designed to collimate, focus, or collect infrared light. At Avantier Inc., we produce high performance IR Optics such as IR lenses for use with near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MIR), and long-wave infrared (LWIR) spectra. These Infrared lenses can be customized for specific areas of the infrared spectrum, and are suitable for applications in defense, life science, medical, research, security, surveillance and other industries.

Our extensive experience in infrared optics enables us to both design and produce the highest quality lenses and assemblies for IR light. State of the art metrology and a robust quality control program means that every lens with the Avantier name on it will perform exactly as intended, and we check and double check that each component meets your full specification. Our manufacturing processes meet all applicable ISO and MIL standards, and our IR lenses are well known throughout the world.

Our experienced engineers and consultants can help you determine the best substrate and antireflective or reflective coating best fits your application. Every situation is unique, and we can help you find a cost effective solution that meets your need. Whether you need special resistance to mechanical and thermal shock, or good performance in rugged environments, we can select the perfect substrate for you.  We can also help design your IR lens or optical lens assembly. From basic lens selection (singlet, aspherical lens, spheric lens, cylindrical lens, custom shape lens) to design of aspheric lenses arranged in a complex opto-mechanical device, or any other infrared optical assembly, we have you covered.

Vertical translationand horizontaltranslation

Horizontal Translation: Horizontal translation is the process of shifting a graph left or right on the coordinate plane without changing its shape or size. It involves adding or subtracting a constant value to the input of a function.

The period of a periodic function is the distance or time it takes for the function to complete one full cycle, repeating the same pattern.

The substrate chosen for a lens will depend partly on which IR region it is designed for. For instance, Calcium Fluoride  (CaF2) lenses are a good choice for radiation between 80 nm – 8 μm and so would be ideal for NIR SWIR wavelengths. Zinc Selenide has optimal transmission from 8 – 12μm, although it offers partial transmission over 0.45 μm to 21.5 μm  and  Zinc Sulfide (good transmission in 8-12µm,  or partial transmission from 0.35 to 14µm).
