Accurate Optics

In the realm of machine vision and precision imaging, accurate measurement and dimensional analysis are crucial. However, traditional lenses often introduce perspective error and depth of field limitations, leading to inaccurate measurements and compromised image quality. To overcome these challenges, telecentric lenses have emerged as powerful tools. In this blog post, we will explore how telecentric lenses effectively eliminate perspective error and depth of field issues, revolutionizing applications that demand precise measurements and high image fidelity. 1. Understanding Perspective Error: Perspective error occurs when the size or shape of an object appears distorted due to variations in distance from the lens. Traditional lenses have a perspective projection, causing objects closer to the lens to appear larger and objects farther away to appear smaller. This perspective distortion can introduce inaccuracies in measurements and image analysis. 2. The Principle of Telecentricity: ...
