Infrared optical products

Infrared (IR) is characterized by a wavelength between 0.750 -1000μm (750-1000000nm). Due to the limitation of the detector range, IR radiation is usually divided into the following three smaller areas: 0.750-3μm, 3-30μm and 30-1000μm, respectively defined as near infrared (NIR), mid-wave infrared (MWIR) and far infrared (FIR) . Infrared products are widely used in a variety of applications from IR signal detection in thermal imaging to element identification in IR spectroscopy. With the development of IR application requirements and technological progress, manufacturers have begun to use IR materials to design flat optical components (such as (ie windows, mirrors, polarizers, beam splitters, prisms), spherical lenses (such as plano-concave/plano-convex lenses) , Biconcave/biconvex lens, meniscus lens), aspheric lens (parabolic, hyperboloid, hybrid lens), achromatic lens, and assembly components (such as imaging lens, beam expander, eyepiece, objective lens). These IR materials or The physical properties of the substrate are different. Therefore, understanding the advantages of each material can select the right material for any IR application.
