Scope
ISO 10110 specifies the presentation of design and functional requirements for optical elements in technicaldrawings used for manufacturing and inspection.
This part of ISO 10110 specifies rules for the indication of the damage threshold from laser irradiation up towhich optical surfaces shall not exhibit any damage as defined in ISO 11254-1.

3 Terms and definitions
For the purposes of this document the terms and definitions given in ISO 11145, ISO 11254-1 and thefollowing apply.
3.1
wavelength
λ wavelength of the laser radiation
3.2
threshold
highest quantity of laser radiation incident upon the optical surface for which the extrapolated probability of damage is zero
NOTE The quantity of laser radiation may be expressed in energy density H max or power density E max .
[ISO 1 1 254-1 :2000]
3.3
effective pulse duration
τ eff
〈laser pulse〉 ratio of the total pulse energy to maximum pulse power
[ISO 1 1 254-1 :2000]
3.4
threshold energy density
H th
〈pulsed laser irradiation〉 energy density threshold, expressed in joules per square centimetre, above which damage may occur
3.5
threshold power density
E th
〈pulsed laser irradiation〉 power density threshold, expressed in watts per square centimetre, above which damage may occur
3.6
threshold linear power density
F th
〈continuous wave and long pulse laser irradiation〉 linear power density threshold, expressed in watts per centimetre, above which damage may occur
NOTE For laser damage considerations a long pulse is when the thermal transit distance, (2 D τ eff ) 1 /2 , where D is the thermal diffusivity, is in the order of the size of the test spot d T,eff .
4 Other test parameters
Any other test parameters shall be in accordance with the relevant parts of ISO 1 1 254. For certain optical elements it may be necessary to specify the state and plane of polarization as well as the angle of incidence.
5 Specifications
5.1 General
