Elliot Scientific Band Pass filters are manufactured from Schott's renowned high-quality ionically or colloidally coloured glass to selectively transmit a particular spectral range. The colour group name gives an approximate idea of what wavelengths are transmitted, however it is always best to consult the product datasheet (see the Related Documents menu to the right) for in-depth information and other specifications. Custom sizes can be manufactured upon request.
