I have a few questions regarding the standard Whitmore design MFT system that we have at Winterthur.
1) What type of Xe lamp have people selected for MFT using the Whitmore design: standard or ozone free? The latter generates less UV, but unless one is interested in UV induced fading or optical brighteners visible light (400-700 nm) should suffice.
2) Has anyone used a 100 W Xe arc lamp instead of the 75 W lamp that seems to be the standard choice?
3) Our Whitmore MFT system at Winterthur also has a water filter installed on the Xe arc lamp housing, but the filter is empty and infrared radiation is instead removed by a glass optical filter. Have MFT users with similar systems removed the water filters since they are no longer needed (and generally require some type of temperature stabilized water circulation to use)?
Thanks in advance for any advice you can share!
Best regards,
Mike Crawford
