An inside look at how Shanghai Optics engineers measure transmittance using a Spectrophotometer.
Spectrophotometers measure transmittance and reflectance of lenses and lens assemblies (objectives). This process is designed to measure coatings on lenses.
0:12 - Step 1: Initialize the Spectrometer
0:23 - Step 2: Insert the polarizer
0:34 - Step 3: Set test parameters (wavelength, incident angle, polarization type, etc.)
0:39 - Step 4: Calibrate the baseline
0:49 - Step 5: Place the witness piece
1:07 - Step 6: Measure spectral reflectance curve
