Wavelengths

These are the wavelengths and wavelength coverage regions of the optical channels that are normally available for our various instruments including:Partial selection of available channelsPartial selection of available channels

The table below shows the center wavelengths we offer. The nominal bandwidth of these channels is 10 nm. Filters used are specified for high levels of blocking, and are assembled to minimize any fluorescence. Filters are typically "hard coat" or ion-deposited technology, known for its great resistance to moisture, low temperature coefficient, and long term stability.

Please note that the OSPREy instruments also are available (optional) with spectrograph coverage as follows:

  • 245–785 nm, 6–8 nm bandwidth
  • 310–1100 nm, 9–10 nm bandwidth

* Note: The 305 nm wider bandwidth is optimized for sharp cutoff with longer wavelengths to give greatest sensitivity to the ozone cutoff region.
