Keratometer Optical Design
In this article, we will continue our description of different optical instruments used by optometrists. Last time we talked about Ophthalmoscopes, today we will talk about another very common optical instrument called the Keratometer. The keratometer was developed in 1851, it is used to measure the curvature of the anterior cornea. That is the outer […]
Laser and Adaptive Headlight Tech Explained
In the past we have talked about LiDAR and its use in auto industry, there are many more examples of optical engineering in the auto industry. One good example are the new adaptive headlights that protect the driver from glare. The US National Highway Traffic Safety Administration (NHTSA) has lifted some of the bans that […]
Wobble Welding Explained
In the dynamic landscape of industrial manufacturing, advancements in welding technologies continually push the boundaries of precision and efficiency. Among these innovations, wobble welding has become an essential technique, combining the power of industrial laser technology with scanning mirrors to redefine the possibilities of welding across various materials. In this article, we delve deep into […]
Cardinal Points
When I was a young undergrad engineering student, I always found optics to be a very confusing subject. It was not only the equations, but what it looked like hundreds of different definitions involved in even the simplest of optical systems. Some concepts, like radius of curvature, f-number, and focal point were easy to understand […]
