Dispersive Prism
A dispersive prism is an optical element used to break up light into its different wavelength components - a phenomenon discovered by Sir Isaac Newton. By doing this, the prism separates light of varying wavelengths, with longer wavelengths (red) deflecting at a...
3 Rules For Plano Convex Lens Design
Plano convex lenses are lenses with a positive focal length and while they are simple compared to many optical systems, but there are fine details that a lens designer needs to pay attention to. This post will review 3 key rules for designing a plano convex lens

Optics in the News – June 2022
Complex Optical Components from Fluids. Researchers from the Israel Institute of Technology have developed a new technique to fabricate free-form optics by curing a liquid polymer. Traditionally, free-form optics are fabricated using complex CNC equipment that...
Calcium Fluoride Glass: An Overview
The choice of glass is a fundamental part in the optical design process. This is especially true for IR and thermal optics materials. In this article, we will review Calcium Fluoride (CaF2), an interesting glass that has a wide range of applications. Before we start,...
Light Source Safety Calculator
One important aspect of any design is user safety. This is especially important when using light sources like lasers and LEDs that may be observed by the naked eye. Disregarding safety can lead to product recalls, lawsuits, and harm to users. To protect users, a...
Deciphering 4f Optical Systems: A Journey into Fourier Optics
Introduction A 4F optical system is a system architecture that uses Fourier Optics. In this article, we will explain why we need them and how to design a simple 4f correlator. We will leave out most of the mathematical derivations, but if you are interested...
How Aspheric and Freeform lenses work
A key aspect of an optical product development is the creation of a quality optical system design optimized to reduce aberrations and system cost. In an attempt to reach a balance between cost and performance, optical designers have created lenses with different...
