OEOSC Accredited Course: Introduction to Modern Optical Drawings – the ISO 10110 Standard (SPIE Course SC863)

Since the late 1990s, the optics community has gradually been converting optics drawings from a free-form, notes-based method to a standardized, international pictographic method. In 2013, the United States joined the international community by adopting a version of ISO 10110 as the American National Standard for optics drawings. This new method is a great boon for an industry in need of standardization, but it can be very confusing to the uninitiated. In addition, the standard has continued to evolve with new revisions and additions to address the needs of more applications and markets. This course provides attendees with an introduction to ISO 10110, the international standard for optics drawing notations. The course concentrates on the fundamentals of the drawing layout and how to read the notations required for typical optics, such as glass parameters, radius, wave-front, surface imperfections, and roughness. Attendees are also informed about how the American version differs from the current international standard. Practical and useful examples are included throughout.

Learning Outcomes

• read and interpret an optical drawing prepared to ISO 10110
• identify the meaning of the symbology and specifications of ISO 10110 for materials imperfections, surface form, wedge, surface imperfections, and surface texture
• describe which symbol corresponds to each of the fundamental optical parameters
• compose and interpret an ISO 10110-compliant optical element drawing

OEOSC Accredited Course: Understanding Scratch and Dig Specifications (SPIE Course SC700)

Surface imperfection specifications (i.e. Scratch-Dig) are among the most misunderstood, misinterpreted, and ambiguous of all optics component specifications. This course provides attendees with an understanding of the source of ambiguity in surface imperfection specifications, and provides the context needed to properly specify surface imperfections using a variety of specification standards, and to evaluate a given optic to a particular level of surface imperfection specification. The course will focus on the differences and application of the Mil-PRF-13830, ISO 10110-7, and ANSI OP1.002. Many practical and useful specification examples are included throughout, as well as a hands-on demonstration on visual comparison evaluation techniques.

The course is followed by SC1017 Optics Surface Inspection Workshop, which provides hands-on experience conducting inspections using the specification information provided in this course.

Learning outcomes

• describe the various surface imperfection specifications that exist today
• compose a meaningful surface imperfection specification for cosmetic imperfections using ISO, ANSI, or Mil standards
• identify the different illumination methods and comparison standards for evaluation
• demonstrate a surface imperfection visual inspection
• understand the options available for controlling surface imperfections in a vendor/supplier relationship
