LLS #6: Evaluating Lens Design When designing a lens or choosing a lens, it's important to know if the lens is good enough for your application. Having a suite of analysis types is an important part of this process. In this post we will cover five analysis types that can be used to evaluate lens

LLS #5: Aspheric Lenses In LLS #4: Designing Laser Lenses we found that lenses using only spherical surfaces have some amount of spherical aberration. The magnitude of the spherical aberration can be quite small or quite large depending on focal length, laser beam diameter, lens shape, and index of refraction of the lens material.
LLS #4: Designing Laser Lenses Designing lenses for a laser application is simplified by the fact that the lens must work at only one wavelength – the wavelength of the laser. This is true for most laser applications, but there are some exceptions which might be discussed in later posts. Lensmaker's Equation The basic lens is
LLS #3: Basic Lens Types For most laser systems there are mainly 6 types of lenses that are commonly used to change that shape of a laser beam. These can be broken down into two groups: positive focal length lenses and negative focal length lenses. Positive Focal Length Lens Types In most laser applications we
LLS #2: Laser Beam Divergence Laser beam divergence is a characteristic of all laser beams. This is one of those fundamental rules of coherent light and it is governed by a pretty simple equation. In this equation θ is the half angle beam divergence. The other symbols are: λ is the wavelength of the laser
LLS #1: Lenses and Lasers, A Necessary Connection The unsung hero of the laser industry is the lens (slight hyperbole 😊). Today we can find a host of content on the internet about the pervasiveness of lasers. In fact, it would be safe to say that lasers have shaped our society as much as computers and cell phones. Without
Lenses and Lasers Series (LLS) This is a series about the interconnection between lenses and lasers. In this series of posts, we'll talk about lasers and the beams they generate, and how optical lenses enable laser beams do work in most laser applications. The main focus (excuse the pun) of these posts is how to
