One of the greatest problems of our industry today is the scratch and dig specification. It is the most misunderstood and misapplied requirement for optics and the most commonly cited cause for rejection, despite being, for the most part, a subjective examination of workmanship issues.
For more than ten years, Savvy Optics has been on a mission to solve the scratch and dig problem by offering training and education, products and services aimed at demystifying and standardizing the surface imperfection standards of the world.
A key part of that effort is standardizing the meaning of the scratch and dig numbers. Since there is significant variation in make and model of the different comparison standards, it is essential that the comparison standards and measurement equipment be maintained and verified periodically.
Starting in 2009 we began offering the SavvyInspector(r) technology world-wide, allowing Army traceable, objective scratch and dig measurements. Systems should be calibrated periodically to maintain proper measurement. We can come to your site, evaluate the system, check the performance against the Savvy Optics reference masters, and calibrate the system. Contact us to arrange for a visit.
Starting in 2012, at the request of customers, we began offering certification of comparison standards using our SavvyInspector(r) technology. For a very modest fee, we will inspect your comparison standard and provide a report of the scratch brightness and dig sizes, and certify the set against either Army or OEM standard values. All certifications are ISO 17025 and MIL-STD-45662A compliant. Scratch measurements are Army traceable, while dig measurements are NIST traceable.
