Where Can I Find Data on the IR Transmission of Silicon and Germanium?

Click For Summary
SUMMARY

The discussion focuses on obtaining electronic data for the infrared (IR) transmission properties of Silicon (Si) and Germanium (Ge) within the wavelength range of 1-15 micrometers (µm). A specific resource mentioned is a PDF from the University of Vienna that outlines the optical properties of silicon. The conversation highlights that silicon exhibits absorption bands at lower wavelengths, and its transmittance is influenced by material thickness. Users are seeking accessible formats like text files or CSVs for this data.

PREREQUISITES
  • Understanding of infrared transmission properties
  • Familiarity with optical materials, specifically Silicon and Germanium
  • Knowledge of data formats such as CSV and text files
  • Basic comprehension of absorption bands and their effects on transmittance
NEXT STEPS
  • Research the optical properties of Silicon and Germanium in the mid-infrared spectrum
  • Explore databases or repositories for optical transmission data
  • Learn about the impact of material thickness on transmittance
  • Investigate additional academic resources or publications on IR transmission
USEFUL FOR

Researchers, optical engineers, and materials scientists interested in the infrared transmission characteristics of Silicon and Germanium, as well as those seeking data for photovoltaic applications.

I'm looking for a table of data in electronic format, for optical transmission of Si in the mid infrared at say a wavelength range of 1-15um.

Something like a text file or CSV file from a public source?

Also looking for Germanium - the same spectrum.

Any suggestions where I could get this?

At the lower wavelegth range, silicon has got some absorption bands and its transmittance depends on thickness.
