Heidelberg - Jena - Database of Optical Constants (HEJDOC)

WWW databases of optical constants:

1. Database on X-ray interaction with matter
   The database includes a lot of things related to the problem. In particular it allows one to obtain "optical" properties of different materials in the energy range from 30 up to 30.000 eV.
   
2. Database of solid CO and CO₂ for ISO
   The database contains files with the optical constants of apolar and polar ices. The data were derived from laboratory measured infrared spectra of mixtures containing CO and CO₂ at temperatures between 10 and 80 K.
   
3. Ice analogs database
   In the database one can find the infrared spectra of laboratory analogs of interstellar ices. The analogs consist of mixtures of the molecules H₂, H₂O, NH₃, CH₄, CO, H₂CO, CH₃OH, O₂, N₂, and CO₂.
   
4. Jena Laboratory database
   Optical constants of many materials of astronomical interest have been determined in the laboratory of Friedrich-Schiller-University (Jena). Files with the data have free access.
   
5. Optical constants of some astrophysical materials
   Now HTML access to files with the optical constants of astronomical silicate, graphite, PAH-graphite, and silicon carbide very often used in astrophysics.
   
6. Optical properties of materials used in applications
   On the pages of Crystran Ltd one can find tables with optical, physical and chemical characteristics of materials (silicon, sapphire, crystal quartz, fused silica, MgO, etc) used in the manufacture of optics for infrared and ultraviolet applications.
   
7. Characteristics and properties of semiconductor materials
   This part of the Ioffe Institute site describes various physical (and optical) properties of many semiconductor materials (incl. Si and diamond). There is also a graphics library of the optical constants in visual for a more wide group of materials.
   
8. HITRAN's aerosol indices of refraction
   HITRAN - High resolution transmission molecular absorption database has produced files with the refractive index of aerosol. Its page includes links to other spectral databases.
   
9. U.S.Geological Survey database
   Digital spectral library of minerals from 0.2 to 3 um (splib04a) as well as other spectral libraries, software and useful information on (imaging) spectroscopy (incl. that of planets) are available.
   
10. ASTER spectral database
    A compilation of almost 2000 spectra of natural and man made materials.
    
11. Atomic Line List
    A list of lines of various atoms.
    
12. Infrared Spectral Database of Polycyclic Aromatic Hydrocarbons
    This database host spectra (graphical/ASCII/HTML) for many neutral and cationic PAHs.
    
13. Solid Spectroscopy Hosting Architecture of Databases and Expertise
    A Spectral and photometric data from ices, minerals, rocks, organic and carbonaceous materials obtained by various spectroscopic techniques over the whole electromagnetic spectrum.
