High Surface Flatness Mirror 50.8mm Diameter 248nm
HTFM-50.8C11-248
High Surface Accuracy Mirrors are realized by optimizing the conditions of the substrate material, thickness and coating. A surface accuracy of λ/10 after coating is guaranteed on these mirrors.
◦This product features a surface accuracy (after coating) higher than our standard dielectric multi-layer flat mirrors (TFM).
◦By using synthetic fused silica and increasing the substrate thickness the rigidity of the mirrors are increased.
◦Our product line includes mirrors with high-reflection for use in individual wavelengths including ultra-violet,YAG and other lasers.
