Precision shims, spacers and rings lapped and polished

Spacers, Shims, Rings, Washers Sized to Micron Levels

Spacer and submount components from Valley Design with accurate pitch tolerances and sequentially spaced to less than 1/4 micron, flat to less than 1/10 wave, with lapped or polished mirror finishes available.

Spacers, shims, submounts, rings, washers, and blocks can be manufactured from many various materials. Shims of all sizes, thicknesses, and surface finishes can be precisely manufactured to your specifications for a variety of applications. These spacers and shims can be made from various materials including Aluminum Nitride, Alumina, Fused Silica, Fused Quartz, Soda Lime Glass and Borosilicate glass. Many of these are readily available from stock (see below). Other materials include stainless steel, tool steel, copper, brass, aluminum, tungsten, nickel plated or hardcoated metals, Silicon Carbide, glass of all types, quartz, sapphire, teflon, polymers and many others. These can be custom shaped, lapped or polished to perfection. Custom edge profiles and cavities are also available. shims - spacers

Capabilities range from blocks as small as 250 microns square and as thin as 25 microns to rings as large as 450mm diameter. These can be sequentially spaced with various edge profiles, steps and cavities. Valley Design has a very wide range of capabilities and can tackle even the most challenging specifications and tight tolerances. Almost any custom part can be fabricated. Contact us for all your precision shims, spacers, blocks and washers, lapped or polished, any flat shape, with or without cavities or holes.
