How to plot reflectance graph from absorption/transmittance graph taken from UV-Vis spectrophotometer for thin film?
Dear colleague Ram Prasanth Ramesh
Have a nice time and good day, Happy new year.
Peace be up on you, your question's readers and all RG members.
Transmittance, T , reflectance, R and Absorbance, A
A+R+T =1
So R=1-(A+T)
I wish this is useful and help you.
Yours

Absorbance = Constant/Reflectance
Dear
You can open your data in same instrument. Convert the Y axis into Reflectance by clicking conversion of Y axis tab. collect the data plot the graph. Enjoy the day. Any doubt you can ask.
Dear Ram Prasanth Ramesh,
1. Reflectance (R) is the amount of reflected radiation over the amount of
incoming radiation power.
2. Absorption (A) is the amount of absorbed radiation over the amount of
3. Transmittance (T) is the amount of transmitted radiation over the
incident power.
Power continuity dictates that:
R + A + T = 1
This expression is known as Kirchoff's law. For an opaque object (T=0), what is not absorbed gets reflected. ie. R + A = 1.
Put Reflectance on Y axis and plot the graph.
I hope I have answered your question.
With Best Wishes,
