Review EDMUND OPTICS Inch Diameter Zerodur Optical Flat Best Offer

The Edmund Optics 43427 Zerodur Optical Flat is a high-precision, optically flat mirror designed for use in metrology applications where the highest level of surface accuracy and flatness are required. This optical flat is manufactured using Schott Zerodur glass, which is renowned for its ultra-low thermal expansion coefficient, making it ideal for temperature-sensitive applications.

The Zerodur glass is polished to an extremely high surface quality, achieving a surface figure error of less than /10 at 633nm wavelength and a surface roughness of less than 1.0 nm Ra. The flatness of this optical component is also exceptional, with a measured flatness error of less than /100 at 633nm wavelength.

The Edmund Optics 43427 Zerodur Optical Flat is available in two sizes: 100mm x 100mm and 200mm x 200mm. It has a thickness of 25mm, making it suitable for use in both air and vacuum environments. The optical flat is also coated with a highly reflective, broadband aluminum coating to ensure maximum reflectivity across the visible and near-infrared spectral range.

The optical flat is supplied in a protective carrying case and includes a calibration certificate, which verifies its surface quality and flatness at the time of manufacture. The carrying case also includes a leveling foot, which allows the optical flat to be securely mounted and precisely aligned for use in metrology applications.

Overall, the Edmund Optics 43427 Zerodur Optical Flat is an essential tool for any metrology laboratory or optical testing facility where the highest levels of surface accuracy and flatness are required. Its exceptional surface quality, flatness, and temperature stability make it an ideal choice for applications such as wavefront sensing, interferometry, and surface profilometry.
