available that accepts 32 mm diameter filters.
Filter wheels designed for use with 1 inch or 25 mm filters will accept filters with a thickness
that does not exceed the following dimensions:
▪
mm (0.18 in.) for Slide-in filter holders
•
5.38 mm (0.21 in.) for Drop-in filter holders
•
9 mm (0.35 in.) for Filter cups
Filter wheels designed for use with 32 mm filters will accept filters with a thickness that does
not exceed the following dimensions:
• 9 mm (0.35 in.) for Filter cups
Instructions for installing filters into the filter wheel can be found in the FILTER WHEEL
chapter of this manual. Sutter Instrument Company does not supply filters but filters
conforming to the above specifications can be purchased from any filter manufacturer.

1.3.4 Slide-in or Drop-in Filter Holders

Many users prefer having extra Slide-in or Drop-in filter holders for more convenient
replacement of these "fixed" filters. Only use filter holders made by Sutter Instrument
Company in the LAMBDA 10-B Filter Wheel. Extra filter holders for one-inch wheels are
readily available from Sutter Instrument Company or their distributors and are listed as
