“Own research and development are a guarantee for innovative products.“

Consistent education and practical experience over years enable our team to develop special methods and techniques which constantly and substantially improve our products.

Some of our developments are:

• Band-pass filters with low filter thickness (up to 0.6mm) at different wavelengths; blocked from x-ray to NIR
• UV-filters with high transmissions (instead of 15-20% up to 40-60% transmission)
• Filters with extreme edge steepness and very low full width at half maximum (FWHM)
• Notch filters with high blocking (up to 10⁻⁸)
