This paper shows the optical transmission evaluated for the two manufactured optical correctors of VST telescope. It reports the external transmission curves and corresponding data values for the two correctors camera which have been designed from Technology Working Group at INAF Astronomical Observatory of Capodimonte in Napoli in collaboration with ESO and realized by Zeiss as part of the whole telescope optical design. The transmission for two-lens corrector and ADC and one-lens corrector, has been analyzed in the wavelength ranges of measured Zeiss AR coating curves. The specifications for antireflection coating of optical components of VST correctors have been given on a wide range (320 ÷ 1014 nm). The transmission curves have been computed at different fields of view positions from the center, in order to analyze if there were significant differences with components glass thickness variation. The transmission values reported will be of reference for the phases of test of the correctors mounted at telescope at Paranal and for the correlated tests and commissioning of the telescope with focal plane camera OMEGACAM.

Abstract
This paper shows the optical transmission evaluated for the two manufactured optical correctors of VST telescope. It reports the external transmission curves and corresponding data values for the two correctors camera which have been designed from Technology Working Group at INAF Astronomical Observatory of Capodimonte in Napoli in collaboration with ESO and realized by Zeiss as part of the whole telescope optical design. The transmission for two-lens corrector and ADC and one-lens corrector, has been analyzed in the wavelength ranges of measured Zeiss AR coating curves. The specifications for antireflection coating of optical components of VST correctors have been given on a wide range (320 ÷ 1014 nm). The transmission curves have been computed at different fields of view positions from the center, in order to analyze if there were significant differences with components glass thickness variation. The transmission values reported will be of reference for the phases of test of the correctors mounted at telescope at Paranal and for the correlated tests and commissioning of the telescope with focal plane camera OMEGACAM.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
