Optical coating definitions and standards
by SergeySidorovich | optical engineering, lens design, optical design
According to ISO 10110 standard, optical coatings are divided into protective and functional coatings. Protective types are coated onto optical elements when the safety of optical surfaces matters and a functional coating is needed. For example, an optical device to...
Radius of curvature requirement in optical drawings
by SergeySidorovich | lens design, optical design, optical engineering
Based on ISO 10110 standard, one of the key parameters in optical drawings is the radius of curvature of lens surfaces. It is specified on the first line of the surfaces column in the table of parameters. You can click here to review. The lens optical properties are...
Datum Surface In Optical Drawings
by SergeySidorovich | optical design, optical engineering
Updated June 2020. Our recent post described how to read optical production drawings. One of the parameters frequently found in optical drawings, "Datum Surface," should be covered more closely. Datum definition As defined by both ISO and ANSI technical standards,...
Surface texture requirement in optical drawings
by SergeySidorovich | lens design, optical design, optical engineering, optics
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...
Mastering Optics Production Drawings: A Comprehensive Guide to ISO 10110 Standards
by John | lens design, optical engineering
Introduction Optics production drawings play a pivotal role in the manufacturing process of optical components, devices, and systems. These drawings serve as detailed blueprints that guide engineers, technicians, and manufacturers in fabricating precise and...
Could Cree reps be providing incorrect data? (it’s complicated)
by John | LED, optical engineering
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...
Stronger patents: surprising lessons from litigation and sale
by John | patents, optical engineering
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...
