METHOD OF MEASURING LENS TRANSMITTANCE |
摘要 |
FIELD: physics. ^ SUBSTANCE: two controlled lenses are used. First lens is illuminated by parallel light flow. Lens focal points are aligned to register parallel light flow from second lens of photo receiving system. Parallel light flow is directed by flat mirrors onto photo receiving system lens to register light flow at lens inputs. Instead of second lens, mirror with spherical or parabolic surface is arranged to align focal points of mirror and first lens and register parallel light flow reflected by said mirror. Instead of first lens, second lens is arranged to align its focal point with that of mirror register parallel light flow. Transmittance is calculated by formulae covered by this invention. ^ EFFECT: simplified transmittance determination and higher accuracy. ^ 1 dwg |
