Elliptical Mirror, 26.97mm Minor Axis, 320 – 450nm

Product Details Circular Profile When Oriented at 45° Average Reflectivity >99% Over Broad UV, Visible, and NIR Wavelengths Enhanced Reflectivity and LIDT over Metallic Coatings TECHSPEC Broadband Dielectric Elliptical Flat Mirrors are ideal for research and astronomical applications. Because of their elongated major axis, they are suited to bending and folding light at precise angles with minimum wavefront distortion. These mirrors feature greater than 99% reflection, significantly better than metal-coated mirrors, and increase system performance by minimizing energy loss. TECHSPEC Broadband Dielectric Elliptical Flat Mirrors feature a BOROFLOAT substrate and are available with minor axes up to 76.20mm and major axes up to 107.77mm Specifications General Type: Flat Mirror Note: Flatness specification is Peak to Valley Physical & Mechanical Properties Dimensional Tolerance (mm): ±0.38 Dimensional Tolerance (inches): ±0.015 Thickness (mm): 6.35 ±0.76 Thickness Tolerance (inches): ±0.030 Clear Aperture CA (mm): 24.28 (Minor Axis) 34.34 (Major Axis) Minor Axis (mm): 26.97 Major Axis (mm): 38.15 Optical Properties Substrate: Many glass manufacturers offer the same material characteristics under different trade names.
