Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 11551 was prepared by Technical Committee
ISOnC 172, Optics and optical instruments, Subcommittee SC 9, Electro-
optical systems.
Annex A forms an integral part of this International Standard.

Introduction
To characterize an optical component, it is important to know its
absorptance. When radiation impinges upon a component, a part of that
radiation is absorbed, increasing the temperature of the component. If
enough energy is absorbed, the optical properties of the component may
be changed, and the component may even be destroyed. Absorptance is
the ratio of the radiant flux absorbed to the radiant flux of the incident
radiation.
In the procedures described in this International Standard, the absorptance
is determined calorimetrically as the ratio of power or energy absorbed by
the component to the total power or energy, respectively, impinging upon
the component. The assumption is made that the absorptance of the test
sample is constant within the temperature fluctuations experienced by the
component during the measurement, is constant within the volume of the
component and is independent of the power density of the impinging
radiation. (However, several infrared materials exhibit a strong dependence
of absorptance on temperature, especially at high temperatures.)

Preparation of test sample and measuring arrangement
5
Storage, cleaning and the preparation of the test samples are carried out in accordance with the manufacturer’s
instructions for normal use.
The environment of the testing place consists of dust-free filtered air with less than 60 % relative humidity. The
residual dust is reduced in accordance with cleanroom class 7 as defined in IS0 14644-1. In this connection, an
environment free from draught is very important to keep the heat loss by convection as small as possible.
Concerning particular components with low absorption or special cases of application, it is possible to measure the
absorption in a vacuum (pressure lower than 100 Pa). This is especially recommended when the tested sample has
low thermal conductivity and its thickness is much smaller (more than an order of magnitude) than its
width/diameter.
NOTE - Both the ambient atmosphere and the vacuum pressure can affect the measured absorption. For instance Ge, ZnS
and ZnSe all absorb
