The Cylindrical Concave Metallic Coated Mirror, delicately manufactured by Altechna, generally functions through concentrating light into a thin line without chromatic aberration. These instruments' mirrors operate as reflectors in broadband spectral range as it is metallically coated. Additionally, the typical application for these cylindrical mirrors is either beam expansion or line generation.

These mirrors specially feature the following specifications/properties: (1) a material composition of BK7 (Fused Silica is also available), (2) a surface quality of 40-20 S-D, (3) a surface accuracy of λ/4 @ 632.8nm, (4) a clear aperture of 90% of the diameter, (5) an edge thickness of 5mm, (6) a focal length tolerance of +/- 1% and (7) finally, a laser damage threshold >0.3 J/cm2 for 10ns pulses at 1064nm.
