Choosing Filters Based on Lightsources
When choosing a bandpass filter for different light sources, consider the following features: 1. Center Wavelength (CWL) and Bandwidth (FWHM): Cool LED: Select CWL based on the desired color or specific...

What is Optical Density
In the world of optical filters, optical density (OD) is a crucial parameter that describes how much light the filter blocks. It's essentially a logarithmic measure of the attenuation factor,...
