Stock Specification
SCHOTT Bandpass filters available from stock
A band-pass filter passes frequencies within a certain range and rejects (attenuates) frequencies outside that range
Schott ® Bandpass optical glass filters made from Schott ® colour glass have a specific transmission band surrounded by blocking bands either side that only allow the required section of the spectrum to pass
The Schott® Bandpass filter range includes BG18, BG7, UG11, UG1, UG5
We also have stock of various obsolete Schott materials in raw form including Schott BG24a - Schott BG12 - Schott BG13 - Schott BG14. Where we manufacture standard sizes these will be made available as stock items. All other sizes will be available on request.
Stock Schott filters are available in the sizes below and can be cut to custom sizes if required. We hold stock of raw Schott materials and can quote for custom sizes and production quantities
