SIGMAKOKI UV Enhanced Aluminum Flat Mirror φ25.4mm 170-400nm　TFAE-25.4C05-10

Feature

• A mirror in which aluminum is deposited on a plane substrate that has been polished with high precision.
• High reflectivity can be obtained at all incident angles.
• A protective coating of dielectric multilayers designed to increase the reflectance of visible and ultraviolet light.
• The reflectivity is slightly reduced, but the reflectivity is stable even in visible and infrared light.
• Pyrex (R) is a registered trademark of Corning Corporation.
• * When multiple mirrors are used to propagate light, large amounts of light are lost due to absorption of the aluminum film.
• * Use a dielectric multilayer mirror (TFM, etc.).
• * The reflectance of the specification is expressed as the average value of the reflectance of P-polarized light and S-polarized light.
• * Reflectivity may change depending on the polarization state of the incident beam.
