Elliot Scientific Short Pass filters are manufactured from Schott's renowned high-quality ionically or colloidally coloured glass to selectively block 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 (via the Documents tab above) for in-depth information and other specifications. Custom sizes can be manufactured upon request.
