Infrared

Sometimes you can't see everything with just your eyes. Infrared technology could make it easier to spot any paranormal activity one might have missed.

ISO 11382:2010

Optics and photonics - Optical materials and components - Characterization of optical materials used in the infrared spectral range from 0,78 m to 25 m

ISO 11382 provides guidelines for the description of data sheets for infrared materials. It specifies the nomenclature and the properties of infrared materials which are reported on such data sheets. These data sheets do not necessarily contain information on every property identified in this International Standard.

ISO 11382 also specifies the parameters needed to characterize optical materials intended for use in the infrared spectral range from 0,78 µm to 25 µm and provides various methods to be used for measuring these parameters.

ISO 11382 is applicable only to materials used in the manufacture of passive optical components. The properties of materials used in active applications (e.g. optoelectronics) are not taken into account.

Materials specified in ISO 11382 can also be applicable to other spectral domains (microwaves; visible or UV).

Optics and photonics - Optical materials and components - Test method for homogeneity of infrared optical materials

This document specifies the principle, apparatus, condition, sample, procedure and data processing of measuring homogeneity of infrared optical materials.

It is applicable to the determination of homogeneity of infrared optical materials, such as infrared optical glass, infrared crystals and infrared ceramics, which are opaque to visible wavelengths and whose transmission optical spectra are beyond 0,78 ╡m.

ISO 19741:2018

Optics and photonics - Optical materials and components - Test method for striae in infrared optical materials

This document specifies the principle, apparatus, condition, sample, procedure and data processing of measuring striae in infrared optical materials.

It is applicable to the determination of striae in infrared optical materials, such as infrared optical glass, which is opaque to visible wavelengths and whose transmission optical spectra are beyond 0,78 ╡m.

ISO 19742:2018

Optics and photonics - Optical materials and components - Test method for bubbles and inclusions in infrared optical materials

This document specifies the apparatus, condition, sample, procedure and data processing of measuring bubbles and inclusions in infrared optical materials.

It is applicable to the determination of bubbles and inclusions in infrared optical materials, such as infrared optical glass, infrared crystals and infrared ceramics, which are opaque to visible wavelengths and whose transmission optical spectra are beyond 0,78 ╡m.

ISO 17328:2021

Optics and photonics - Optical materials and components - Test method for refractive index of infrared optical materials

This document provides a standard method for measuring the relative refractive index to the air of infrared materials used in the infrared spectral range from 0,78 µm to 25 µm. This document excludes methods for measuring the refractive index of birefringent materials and methods for measuring the complex refractive index.
