**How Do UV Bandpass Filters Work?**
UV bandpass filters operate based on the principle of interference, where multiple layers of optical coatings are deposited onto a substrate to selectively transmit certain wavelengths of light. These coatings are designed to reflect or absorb unwanted wavelengths while allowing only the desired UV band to pass through. By carefully tuning the thickness and material composition of the coatings, manufacturers can create filters with high transmission efficiency and excellent spectral purity.
