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, let’s look at the transmission window for CaF2 (Figure 1). […]
Top 12 Resources for Mastering Lens Design: A Comprehensive Guide

Introduction Lens design is undeniably a complex and challenging field of study, characterized by its intricate blend of physics, mathematics, and engineering principles. Becoming a truly proficient lens designer isn’t merely a matter of acquiring theoretical knowledge; it necessitates years of hands-on practical experience and a keen understanding of how to apply theoretical concepts to […]
Advanced Apochromatic Lens Design for Exceptional Imaging Quality

In an achromatic lens design, we optimize such that two wavelengths, usually red (590nm) and blue (495nm), focus on the same image plane. This is done to reduce chromatic aberration. In this article, we’ll talk about a similar design type called an Apochromatic lens design. What is an apochromatic lens? The goal of the apochromatic […]
Powering advanced optical design with liquid lenses

Liquid lenses, are a type of optical lens that have a tunable focal length by shaping a liquid electronically. These lenses can be based on voice coil actuation, or based on electrowetting technology, which involves manipulating the surface tension of a conductive liquid droplet by applying an electric field. The core component of an electrowetting-based […]
