Our staff has over 40 years of experience in cutting single crystal and ceramic materials. The cutting department is well equipped with a wide variety of cutting and sawing machines, each providing unique capabilities. For example, one of our diamond wheel ID saws uses a thin blade capable of cutting with only 0.008" of kerf. All of our multiband slurry saws can be fitted with bladepacks having spacing as narrow as 0.020" and as wide as 0.500". Material up to 4.5" high by 7.5" square can be cut, and we can accommodate materials as large as 10" in diameter. Our automated cutting and dicing capabilities can accurately fabricate parts smaller than 1.0 mm shipped individually, on wax, or mounted on different types of tape for use with automated handling equipment.
Our lapping capabilities include both double-sided and single-sided laps. This flexibility gives us the ability to produce flat work down to 1/10th wave and to produce extremely thin pieces made to tight tolerances. We also offer a full range of surface finishes - from machine ground to 2 microinches. Boston Piezo-Optics also offers contract lapping of supplied ceramic materials.
We can provide x-ray orientation on any single crystal material. We have the ability to measure to 1 arc minute. The size can be as small as a few millimeters up to pieces in excess of 12" and weights in excess of 100 pounds.
Our polishing capabilities meet or exceed industry standards. We can use traditional methods available such as pitch and high speed polishing. We also use a proprietary mechanical-chemical polishing process developed to produce a SAW polish on crystal quartz. Polished flatness to 1/20 wave, 1 arc second at 100:1 aspect ratio can be achieved. We have successfully adapted this process for use on several ceramic materials including alumina, lead zirconate titanate, lithium niobate and others. In crystal quartz, the mechanical-chemical polish produces a uniformly smooth surface with a minimum of surface dislocation and sub-surface damage.
BPO can provide a wide range of coating methods and materials in-house. We vapor deposit chrome/gold and chrome for use as electrical contacts for electronic and electro-optic components. We can also provide single and multiple layer antireflection coatings. For more rugged applications we can apply four types of thick film coatings: palladium/silver, fired silver, fired gold, and platinum/gold. For low cost and non-line-of-sight applications, we can apply an electroless nickel or electroless nickel plus gold to lead zirconate titanate, quartz and lithium niobate.
