A complete optical systems design course for general optical engineers! The "first cut" design of an optical system – anything from a telescope to a complicated VR helmet – is usually not done by a specialist but by a more general optical engineer. This book details the basic design principles and techniques for doing so in a clear, concise, "low-math" way that such generalists will readily understand – and appreciate. Practical, step-by-step coverage includes succinct equations, simple diagrams, and clear explanations. The chapter on selecting stock lens (to test a concept or to prove out a possible finished device) should be especially useful.

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

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.

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).

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.

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.
