Schott BG filters are utilized for correction of the sensitivity of silicon receivers, the maximum sensitivity of which is in the range from ca. 800 nm to 900 nm, depending on the type of receiver.  The increase in sensitivity from the blue to the near infrared in detection leads to an over evaluation of the long wave (red) area. By selecting suitable BG glasses this can be compensated for to a certain extent.

   BG 39 is suited for video cameras, whereby the infrared sensitivity must be surpressed to ca. 1200 nm.

   The filter glass types are listed below.  To view the linear transmission curves and data sheet for each, simply point and click on the glass type of your choice.
