I Tested Thin Film Optical Filters: What I Learned About Precision, Performance, and Real-World Applications
When I first started exploring the world of optics, I was struck by how much control we can exert over light with something so incredibly thin. That curiosity led me to thin film optical filters, a fascinating class of coatings that can selectively transmit, reflect, or block specific wavelengths with remarkable precision. These filters play…
