Understanding K Correlation in Optical Design: Managing Stray Light and Light Scattering
In this article, we will explore a critical aspect of optical design: the K correlation, and how it plays a pivotal role in managing issues such as stray light and light scattering in optical systems, and we will discuss the Bidirectional Scattering Distribution Function (BSDF) in greater detail. The Significance of K Correlation In optical […]
Scanning and Fluorescent Microscope Design Steps
Microscopy is a fundamental technique used to analyze samples that are too small to be perceived without magnification. It is used in multiple sciences, from biology, medicine, chemistry to anthropology, and any science where small samples are presented. Early microscopes were simple instruments with just a couple of optical elements. As methods improved, so did […]
Designing a custom spectrometer
We will delve in more detail here on the types of questions we ask our customers when starting a custom spectrometer design program and the various stages of development. Some recent spectrophotometer development tasks included: These programs may include design optimization, improvement of a proven concept prototype, or development of a completely new concept. We […]
Rigid Endoscope Design
Endoscopes are medical devices designed to collect the smallest images from inside the human body. Endoscopes can be divided into two categories: rigid endoscopes, in which relay lenses are stacked together generally creating a high-quality image, and flexible ones-devices of lower cost where a camera is inserted near the tip of the endoscope while the […]
Telecentric Lens Design: Enhancing Precision in Optical Systems
Introduction to Telecentric Lenses An important goal in machine vision applications is taking measurements in a consistent, accurate, and precise manner. This can include measuring the dimensions of manufactured parts to guarantee they are within the design tolerance, or measuring the width of electric tracks in a PCB. For these applications, telecentric lenses can deliver […]
