BS ISO 10110-17 pdf download Optics and photonics — Preparation of drawings for optical elements and systems — Part 17: Laser irradiation damage threshold
ISO 10110 specifies the presentation of design and functional requirements for optical elements in technicaldrawings used for manufacturing and inspection.
This part of lSO 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 ISO11254-1.

3Terms and definitions
For the purposes of this document the terms and definitions given in lSO 11145,ISO 11254-1 and thefollowing apply.
wavelength of the laser radiation3.2
highest quantity of laser radiation incident upon the optical surface for which the extrapolated probability ofdamage is zero
NOTE The quantity of laser radiation may be expressed in energy density Hmax or power density Emax.[ISO 11254-1:2000]
effective pulse durationTeff
《laser pulse ratio of the total pulse energy to maximum pulse power[ISO 11254-1:2000]
threshold energy densityh
(pulsed laser irradiation) energy density threshold, expressed in joules per square centimetre, above whichdamage may occur
threshold power densityEth
(pulsed laser irradiation) power density threshold, expressed in watts per square centimetre, above whichdamage may occur
threshold linear power densityFth
(continuous wave and long pulse laser irradiation) linear power density threshold, expressed in watts percentimetre, above which damage may occur
NOTE For laser damage considerations a long pulse is when the thermal transit distance, (2 D rem)”, where D is thethermal diffusivity, is in the order of the size of the test spot dT,eff-
4Other test parameters
Any other test parameters shall be in accordance with the relevant parts of lS0 11254.For certain opticalelements it may be necessary to specify the state and plane of polarization as well as the angle of incidence.
