Aluminum flat mirror λ/10 TFA-30C05-10 1 piece

It has high reflectance characteristics from the visible range to the near infrared range, and has almost no angle dependency. It is overcoated with MgF2 (magnesium fluoride) to maximize reflectance in the visible range. Material: Borosilicate glass (aluminum film + MgF2 coating) Tolerance: Size/0 to -0.1mm, Thickness/±0.1mm Substrate surface accuracy measurement method: Measure the substrate with a Zygo laser interferometer system Surface accuracy measurement wavelength: 632.8nm Parallelism: within 3 arc minutes Effective surface: 90% of actual diameter Scratch-Dig: 40-20 Model number: TFA-30C05-10 Size (mm): φ30×5t Substrate surface accuracy: λ/10
