Mastering Relay Lens Design: Enhancing Optical Systems | OFH

Introduction Optical relays, an integral component of various optical systems, play a crucial role when the user’s proximity to the observed object is limited or when specific image transformations are required. A prevalent example of this is found in relay lenses, often employed in scenarios where physical closeness to the object is impractical, as seen […]
Projection Lens Design

Projection systems are one of the most common consumer optical devices (probably second to photographic systems). They allow us to view images on a screen (usually) by magnifying and projecting them at distances from a few centimeters to several meters away (like in a movie theater), while maintaining a high quality image. Projection systems are […]
Understanding RMS Wavefront Error: An In-Depth Exploration | OFH

Introduction to RMS Wavefront Error As mentioned in several articles in this blog, aberrations are of great relevance when designing an optical system. The objective being to design a system that creates a “good image”. However, there are different metrics to evaluate what is a “good image”. Most of the time, a customer won’t express […]
