Zenith Polymer® / Spectralon® – Diffuse Reflectance Wavelength Standards
SphereOptics diffuse reflectance standards are made from our proprietary Zenith Polymer and Spectralon reflectance material. This highly reflecting, PTFE-based material is resistant to heat, humidity and exposure to high levels of radiation, making it ideal for use as reflectance standards. Those rare earth oxide doped (holmium, erbium and dysprosium) wavelength standard are available in two sizes of 50 mm and 30 mm diameter. Each standard is packaged in a durable holder with a protective cover and comes in a storage box.
