Wedgewood Technology Service Parts - Filters

Optical Interference Filters for in-line UV photometers

These filters are designed as direct replacements for the standard factory installed filters in Wedgewood Technology/Wedgewood Analytical Model AF42, AF44 and Model AF46 UV analyzers.

They utilize state-of-the-art deposition technology to provide consistent and reliable pass band characteristics for photometric accuracy with hard coatings to ensure resilience under UV light when in use.  All filters are tested before shipment and are guaranteed to fit standard Model AF42, AF44 and Model AF46 UV Analyzer flowcell lamp and detector housings. 

All filter sets are supplied with optical scans detailing pass band characteristics

Filters are available in sets for all models.  Each set includes one measurement filter and one reference filter.  Note that AF46 UV sensors require two sets, one for each wavelength installed.

Two types are available:

• S-A003-0280-00          280nm Filter set for AF44 and AF46 UV Photometer
• S-A003-0280-02          280nm Filter set for AF42 UV Photometer
• S-A003-0254-00          254nm Filter set for AF42, AF44 and AF46 UV Photometer
• S-A003-0280-02          313nm Filter set for AF42, AF44 and AF46 UV Photometer

Filters are available from stock.
Other wavelengths can be supplied upon request.
