Specifications and Tolerances

Precision Optical specializes in manufacturing quality optical components to support our customers’ most critical applications. We continuously endeavor to improve and expand our manufacturing capabilities, thus establishing our reputation as an industry leader in achieving the most difficult prism and optical flat tolerances. We are pleased to offer optical components with excellent surface quality, angles, and optical flatness specifications. Precise tolerances on dimensions, sharp roof edges, thin film coatings and prism assemblies are also readily available.

Precision Optical has a comprehensive understanding of various standard and tolerance formats widely used by the optics industry. We have experience working with many MIL Specs, ANSI/ASME Standards, ISO Specifications and customer-issued quality documents. Our experienced sales and engineering teams carefully review each optical component to identify its most challenging features and devise unique manufacturing solutions. Precision Optical also works closely with customers to explore tolerancing options that can maximize system performance while maintaining competitive pricing.
