Intro to Optical Filters
Explore the Fundamentals
There are many different types of optical filters, each with its own unique properties.
Bandpass Optical Filters
Frequently Asked Questions
What is a bandpass filter? What does "bandwidth" mean? How are optical bandpass filters used?
Fluorescence Filters
Optimize Your Fluorescence Application
Fluorescence occurs when a molecule absorbs light at wavelengths within its absorption band, and then emits light at longer wavelengths within its emission band.
Enhanced Product Filtering
Optical filters can be searched by individual filters and by set. You will also still have access to the e-store left navigation filtering that you are used to from the historic semrock.com to search by wavelength, filter families, fluorophore, filter type, light source, laser wavelength, edge steepness, flatness, application, and more.
If you are a North American laboratory, university, or government agency, please consider placing your order directly with our distribution partner, AVR Optics. Visit AVR Optics
