Scales, Scale Holders & Invar Kits for Alignment

Optical Tooling scales are essential for measuring component positions with respect to a reference line of sight. We have a number of English and metric scales, in various lengths (be sure to match the scale units to those of your optical micrometer). We offer many different types of scale holders, for use on flat machined surfaces, different diameter rollers, or in conjunction with our Invar kits. Our scale levels let you keep your scales plumb or level, minimizing cosine error in the micrometer readings. Our Invar kits and accessories are a “must” in the alignment world, greatly extending the flexibility of your optical scales.
