Lens spacer kit shown below

Features

More Efficient and Effective

Much more efficient and effective than using retaining rings for spacing lenses, the lens tube spacers and washers are ideally suited for making fixed multi-element lens assemblies like collimators and beam expanders. Shown are 1in. and 2-in. lenses with lens tube spacers prior to being installed into a lens tube.

Wide Selection of Spacers

The LT-SP series lens tube spacers are available in seven thicknesses from 0.5 to 25 mm  and have a thin-wall design to maintain a 90% clear aperture. Note that the LT-SP05-PK 0.5 mm thick spacers are made from black Delrin (acetal plastic) and can also be used as protective washers.

Convenient Lens Spacer Kit

Be prepared with an organized kit of lens tube spacers.  The LT10-SP-KT kit includes various spacer rings sized to fit into LT10 and LH-1A 1-in. lens mounts.  The spacers included in the kit range from 0.5 to 25 mm thick and have a thin-wall design to maintain a 90% clear aperture. Note that the 0.5-mm thick spacers are made from black Delrin (acetal plastic) and can also be used as protective washers.  The contents of the kit is as follows: 6 ea. of the following spacer: 1-, 2-, 4-, 8-, 10-, and 25-mm thick spacer rings. 20 ea. 0.5-mm thick Delrin spacers. 6 ea. 1-in. threaded retaining rings and one spanner wrench.

Retaining Ring Wrenches

Retaining ring wrenches and retaining rings are needed to securely clamp the lenses and lens spacers in place.  The new LT-WR retaining ring wrenches, with their thin-wall design, are ideally suited for this task.
