Filters & Etalons
LAYERTEC calculates and produces dielectric filter structures. The filters are sputtered and thus achieve very good mechanical and climatic stability with very low losses due to stray light and absorption.
We can always offer a good price-performance ratio if possible coating tolerances (absolute spectral position) can be corrected by a fine angle adjustment during installation in the laser. We are specialized in complex systems with diameters smaller than 25 mm. For diameters larger than 12 mm, deviations in the spectral position occur. Our error tolerance is less than 0.05 %.
