Filters of the Highest Quality
QuartzLine filters provide the highest level of durability, with a low reflective surface and resistance to extreme temperatures. The refractive index is a mere 1.456, making these filters ideal for any application.
Robust Quartz Glass
Our filters are made from robust quartz glass, with a stress-relief temperature of 1120°C. This makes them ideal for a wide range of applications, from photography to astronomy.
Different Types, Many Possibilities
Our filters come in a wide variety of types, including B270 and plastic. Each filter has its own unique properties, such as the refractive index and surface reflectance, allowing you to tailor your filter to the specific application.
| QuartzLine | B270 | Plastic | |
| Refractive index | 1.456 | 1.523 | 1.58 |
| Surface reflectance | 0.034 | 0.042 | 0.056 |
| Stress-relief temperature | 1120°C | 510°C | 463°C |
Our 4-part handmade frame allows for smoother filter adjustment than a frame made of aluminum.
