TMOS10-12030 fresnel lens transmittance % (STHS34PF80)

I am using the STHS34PF80 sensor with the TMOS10-12030 lens from Fresnel Factory. Does anyone have the transmittance % for wavelengths 5um-20um?

Thanks

Hello jkutteh , 
Did you get the TMOS10-12030 e transmittance ?

Hello,
According to this document https://www.fresnelfactory.com/fresnel_list/en_poly_materialofFresnel.pdf, it seems that the transmittance is 42.81% (because the material of the lens is Poly FIR 200) but I also would like to be sure if I am not wrong.

In addition, in a https://www.st.com/content/ccc/resource/technical/document/application_note/group2/cb/74/5a/92/c0/de/4a/94/DM00914720/files/DM00914720.pdf/jcr:content/translations/en.DM00914720.pdf datasheet (p.14),you can find a 'tutorial' to compute the transmittance. You need to make acquisition without and with the lens, save TOBJECT and use this formula
