LT20-SP1-PK Tens Tube Spacer Set is a set of six black anodized aluminum rings sized to fit into LT20 and LH-2A 2 in. lens mounts. Much more efficient and effective than using retaining rings for spacing lenses, they are ideally suited for making fixed multi-element lens assemblies like collimators and beam expanders. These spacers are 1 mm thick and have a thin-wall design to maintain a 90% clear aperture. LT20-SP series spacers are also avaialble in six additional thicknesses from 0.5 to 25 mm.  Note that the LT20-SP05-PK 0.5-mm thick spacers are made from black Delrin (acetal plastic) and can also be used as protective wahsers.
