Transmission Spectrum- Absolute units?

Click For Summary
SUMMARY

The discussion centers on correcting transmission spectrum data for GaAs and InP by utilizing refractive indices at a wavelength of 1.0 micron. The user seeks clarification on converting transmission percentages, which range from 0-57%, into absolute units, specifically whether this means scaling to a 0-100% range. Additionally, the user inquires if Igor Pro can automatically convert the corrected transmission (T') into decibel units.

PREREQUISITES
  • Understanding of refractive indices for GaAs and InP
  • Knowledge of transmission spectrum data manipulation
  • Familiarity with Igor Pro software
  • Concept of converting transmission values to decibels
NEXT STEPS
  • Research refractive indices of GaAs and InP at 1.0 micron
  • Learn how to convert transmission percentages to absolute units
  • Explore Igor Pro's capabilities for data conversion to decibels
  • Investigate methods for correcting experimental data for reflective losses
USEFUL FOR

Researchers and students in optics, materials science, and experimental physics who are working with transmission spectrum data and require accurate data manipulation techniques.

Homework Statement



In manipulating transmission spectrum data from GaAs and InP I'm told to "Look up the refractive indices of GaAs and InP in the region of  = 1.0 micron, and use these to
correct your experimental data for reflective losses and plot the corrected transmission T’ in
absolute units between lambda = 0.8 and lambda = 1.0 micron." Also Put T' in db units.


The Attempt at a Solution


I understand how to correct for reflection I'm just not sure what he means by absolute units. The transmission is given in percentage and within the range we're working in the percentage is within 0-57%, does he mean to expand this so it goes from 0-100%? Also I'm using Igor pro, will it put T' in decibels for me?

thanks
