Avantier Inc.
Bandpass Filters Specifications of bandpass filters. Commonly used specifications for bandpass filters include peak transmission, center wavelength, full-width half-maximum, cut-on and cut-off wavelengths, pass band ripple, edge steepness and blocking. Peak transmission refers to the maximum transmission of the filter, and is usually given in percent. For instance, if a bandpass filter has 92% peak transmission 92% of the most freely transmitted light is passed through the filter. Center wavelength (CWL) refers... (read more) -

Filtertech, Inc.
ABS Absorption Filter Many rolling applications require the use of light oil in place of the typical water-soluble coolant. Traditionally clarification of the roll oils has been done with disposable cartridge filters or diatomaceous earth filters. These methods, while effective, are maintenance intensive and require disposable guard filters. To address these issues, Filtertech has developed the Model ABS Absorption Filter that is fully automatic and eliminates the need for any precoating or use of disposable filters...
