Thanks for the video! When you were measuring the reflectance, what is there in the 2 holders you are refering to as the reference and the sample? What is the chemical composition on them? Also, is it not necessary to run any baseline scan for this reflectance mode? Does it not have anything to do with the BaSO4 baseline?
We use a spectralon 99% reference on our instrument. Spectralon are calibrated references made of teflon. I have not used BaSO4 for baseline. If you are interested I see an interesting comparizon between references here: www.shimadzu.com/an/sites/shimadzu.com.an/files/pim/pim_document_file/applications/application_note/13902/a639_e.pdf
Hi Neethu, The system is a dual beam instrument comparing the intensity between the 2 beams so there is no absolute measurement of the intensity only a relative one.
Hi, thank you for your nice video, it's very helpful. I just wanna ask , if I wanna take blank sample (ITO glass) so where is the place for blank sample?
Luthfiyah, if I understand you correctly, I believe you are asking where to put a reference sample. The reference port is located on the front side of the integrating sphere. In the video you might notice there is a reference standard used on that port when a reference sample is not used. I hope this answers your question. ~Diana

@@EyringMaterialsCenter Thank you very much. Have a nice day
Hi, is it possible to measure the absolute optical power or intensity of the light falling on the sample in Lambda 950,?.

Nice. Very useful
