Updated June 2020. In our previous article, we discussed how to read optical drawings while in this installment, we will focus on surface finish details. Optical lens performance can be heavily affected by the lens surface roughness. The surface texture symbols are...
The most commonly used standard for optics manufacturing is ISO 10110, first created in 1927. Below we describe some of the key parameters called out in the optics production drawing standard. The image below is of a typical lens drawing. The Drawing Area and Table of...
Many of our LED optical design projects start with a simple calculation. Basically, we tell a client how much mechanical space they need to reserve for a lens to achieve the beam angle or pattern they want. In all cases, the larger the LED chip, the bigger the optic...
OFH analyzes optical patents and patent applications, and also engages as expert witnesses for patent litigation in optics, displays, and 3-D. Throughout my career, I’ve overseen the filing of 30-40 patent applications, including drafting the text so that they’re in...
