AR FILTERS
Prinz Optics offers Antireflection Coatings for UV-, VIS- and NIR-range. Choosing the appropriate coating materials it is possible to minimize reflection for many different substrates. The transmission enhancing effect of the antireflection coating can be achieved for distinct wavelengths or for wavelength ranges. We offer broad band AR4 types and narrow band AR2 types.
| Optical specification | ||
|---|---|---|
| Type | Edge wavelengthl | Maximum of reflection |
| AR4 | 450nm - 650nm | R <= 1% |
| AR4 -850 | 700nm - 900nm | R <= 1% |
| AR2-xxx | xxx = required wavelength | R <= 0,5% |
| AR2 | 550nm | R <0,5% |
