Optical filters let certain wavelengths of light pass through and not others, and they're incredibly important in everything from fluorescence microscopy to astronomy!

Watch to learn about 2 of the main types of filters: absorptive and dichroic

Dichroic filters are especially important for fluorescence imaging applications like PCR systems, genomics, and other biological imaging

Edmund Optics designs and manufactures high-precision filter coatings from prototype to volume production quantities
