What is the difference between Color Filter Glass and Interference coated filter glass?
Color Filter Glass is an optical filter made by doping molten glass with metal oxides or rare-earth elements, causing it to absorb specific wavelengths and transmit others, which gives it its color. Interference Coated Filter Glass is a glass substrate with thin-film layers that uses optical interference to selectively transmit or reflect specific wavelengths. In short, interference filters are for high-precision applications, while color filter glass is often used for simpler, cost-effective filtering.
| (1) Interference Filters | (2) Colored Glass Filters |
 |  |
| Interference Filters, or thin-film filters, work by using wave interference. Multiple ultra-thin layers on a substrate are designed to reflect unwanted wavelengths, while constructively let the desire wavelengths to pass through. | Colored Glass Filters work by absorption. Dyes or metal ions inside the glass absorb unwanted light colors, allowing only the desired color light to pass through. They are more simple and only some certain wavelengths. |
