At Sunex, we get many questions about lens and mount (holder) threads when it comes to board-mount lenses.  In this post, we will explore some of the basic considerations of threaded lens and mount combinations, as opposed to some other common methods, which we will touch on.  Although this post will not be a detailed tutorial of the mechanical engineering theory of thread specifications, a basic understanding of thread spec and tolerance helps to understand…

The general guideline for cleaning optics is “if it’s not dirty, don’t clean it”. Handling optics increases their chances of getting dirty or damaged, so you should clean optics only when necessary. Both the proper cleaning products and proper methods are equally important to cleaning the optic. There are different methods for cleaning and certain specialized optics require particular attention and change in procedures. Below are general guidelines to be used as a reference only…

With the advent of computers and more processing power, the art of lens design has matured. But computers cannot solve the whole problem. A computer can select a configuration and designer optimizes that configuration. Can a machine learning algorithm find the absolute best lens design? Yes, if you try an infinite number of different design form. But..”I still want to be young when we get there!” Hence, the journey of developing an elegant design will…
