| Note: (a) |
Depending on room airflow and temperature variations |
| Note: (b) |
2 sigma standard lab traceable for >0.6THz. For 0.5THz and below add 4% to error |
| Note: (c) |
Back reflections from meter can sometimes cause interference effects with source. Unit should be tilted ~10o in this case |
| Note: (d) For P type and shorter wavelengths derate maximum energy density as follows: |
