Several variations of this target are available; all are fixed frequency bifilar dot arrays in a choice of five different dot spacings and four substrate sizes. With a feature-to-feature accuracy of 1 micron, these patterns allow for extremely accurate testing and qualification of X-Y microscope stages and inspection systems. All targets are NIST traceable and serialized for compliance to MIL-STD-45662A.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDot diameter: 0.50mm\u003c\/li\u003e\n\u003cli\u003eDot spacing: 1.0mm\u003c\/li\u003e\n\u003cli\u003eOverall Accuracy: ±0.0015mm\u003c\/li\u003e\n\u003cli\u003eSubstrate type: Soda lime glass\u003c\/li\u003e\n\u003cli\u003eSubstrate size: 4.5” x 4.5”\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003e  The pattern is formed in durable double layer Chromium (OD \u0026gt; 3.0) on a stable 0.060” soda lime glass substrate.
