This white paper provides a basic practical guide on the benefits of 3-D measurements of aspheres as well as a couple of real-world examples of parts that we have manufactured. This white paper also goes into detail why one may prefer measuring aspheres in 3-D over 2-D, not to review the merits of the individual technologies as they apply to specific shapes. Also, we will distinguish the difference between measuring aspheres in 2-D (waviness) and 3-D (irregularity).

This inspection data reference guide goes into detail on what inspection data is and what all options LaCroix Precision Optics offers. We include our tolerance chart, first article inspection, coating, inspection data, material certifications, certificate of conformance, and ROHS certification in this guide. This will help customers know what we offer in order to verify their optics were made to specification.

This chart will explain the tolerancing limits in regard to surface, dimensional, and aspheric tolerances.  This chart also provides various measurements for standard, precision, and high precision attributes.  This can be beneficial because most customers may not get to see the tolerance limits our engineers use to design the specified lens.  This can also help customers with their own optical design specifications.
