Zenith Polymer Diffuse Reflectance StandardsSphereOptics' diffuse 99 % reflectance standard is used industry-widefor calibration of sphere systems, photometers, optical equipment, andspectrophotometers. The range of grey scale standards are generallyused to determine the linearity of optical detector systems used in colorimeters, spectrophotometers and densitometers.Standards are available in two sizes of 50 mm and 30 mm diameter withreflectance values ranging from 99 % (white) to a 2.5 % grey standard.Reflectance values include 99 %, 80 %, 60 %, 50 %, 25 %, 10 %, 5 %and 2.5 %. Standards are sold individually or in sets of two, four or eightstandards with a free choice of reflectance values. Each standard ispackaged in a durable holder with a protective cover and comes in astorage box.SphereOptics maintains a calibration laboratory in Germany and usesstandards traceable to both the National Institute of Standards andTechnology (NIST) and the Physikalisch-Technische Bundesanstalt(PTB). All standards come with a printed and signed certificate and measurement data in electronic form.Art.-No.ReflectivityDiameterSG 3051SG 3052SG 3055SG 3067SG 3068SG 3070SG 3071SG 3072SG 3073SG 3074SG 3082SG 3083SG 3075SG 3076SG 3046SG 3045SG 3086SG 3087SG 3088SG 3089SG 3044SG 3043 99 % 99 % 80 % 80 % 60 % 60 % 50 % 50 % 25 % 25 % 10 % 10 % 5% 5% 2.5 % 2.5 %Set of 2 2Set of 2 2Set of 4 2Set of 4 2Set of 8 2Set of 8 250 mm30 mm50 mm30 mm50 mm30 mm50 mm30 mm50 mm30 mm50 mm30 mm50 mm30 mm50 mm30 mm50 mm30 mm50 mm30 mm50 mm30 mmCalibration will be performed on a Perkin Elmer Lambda 950, data will be supplied electronicallyin 1 nm steps, 50 nm step printed documentation with NIST/PTB traceability with certificate forthe range from 250 nm - 2450 nm.2Within the sets, reflectivities are selectable.Typical Reflectance - Zenith Polymer Diffuse Reflectance Standard100%90%80%70%% 00175020002250Wavelength (nm)2,5% Standard25% Standard5% Standard50% Standard10% Standard60% StandardMixed Rare Earth Oxide Wavelength StandardThe NIST/PTB traceable wavelength calibration standard is a mixtureof three pure, rare earth oxides of Holmium, Erbium and Dysprosium,Typical Reflectance - Zenith Wavelength Standard100which provides a stable reference for validating the wavelength scale of90spectrophotometers and calibrating monochromators in the 250 nm toArt.-No.DescriptionSG 3333Wavelength standard, 50 mm diameterrare earth oxides mixed into Zenith PolymerSG 3334Wavelength standard, 30 mm diameterrare earth oxides mixed into Zenith Polymer80% Reflectance2450 nm 72269.62315.52361.42407.3mixed into Zenith Polymer , which exhibit distinct absorption peaks and250500750100012501500175020002250Wavelength (nm)Calibration will be performed on a Perkin Elmer Lambda 950, data will be supplied electronicallyin 0.1 nm steps, 50 nm step printed documentation with NIST/PTB traceability with certificate forthe range from 250 nm - 2450 nm.APPLICATIONS:Calibration of: Sphere Systems Photometers, Radiometers & Spectrophotometers Densitometers & Optical EquipmentTest Linearity of: Detector Systems Colorimeters, Densitometers & SpectrophotometersZenith Polymer Diffuse Reflectance Standards, Targets and Materials I 3
Zenith Lite Diffuse TargetsZenith Lite diffuse targets are made from our Zenith Polymer diffuse reflectance material, which provides nearly ideal diffuse lambertianreflectance over the wavelength range from 250 nm to 2450 nm. Zenith Lite targets are constructed using a 1 mm or 2 mm thick ZenithPolymer panel laminated with a special adhesive to a 10 mm - 20 mmthick aluminium honeycomb structured plate that serves as a solid, butlightweight backing. They are the ideal choice for both laboratory andfield applications since they are lightweight and can withstand harsh environments for long exposure periods. Due to their design, very flexiblemounting solutions are possible.The laminating technique used with Zenith Lite diffuse targets allowsfor multiple reflectance values in one target with almost no visible seams.Targets can be made to any size and combination of white or greyscalereflectance. The aluminium backing can be drilled to allow attachmentto a variety of mounting devices. Even with a 1 mm or 2 mm Zenith film,the diffuse optical properties are maintained.All targets can be provided with National Institute of Standards and Technology (NIST) / Physikalisch-Technische Bundesanstalt (PTB) traceablecalibration certificates from 250 nm to 2450 nm. For the targets biggerthan 300 mm x 300 mm a smaller reference target (witness sample) isprovided and the calibration is performed on the reference.Art.-No.ReflectivityDimensionsSG 3151SG 3152SG 3153SG 3154SG 3171SG 3155SG 3166SG 3167SG 3168SG 3169SG 3172SG 3170SG 3156SG 3157SG 3158SG 3159SG 3173SG 3160SG 3161SG 3162SG 3163SG 3164SG 3174SG 3165 95 % 90 % 50 % 20 % 10 % 5% 95 % 90 % 50 % 20 % 10 % 5% 95 % 90 % 50 % 20 % 10 % 5% 95 % 90 % 50 % 20 % 10 % 5%200x200x12 mm (approx. 8x8 inch)200x200x11 mm (approx. 8x8 inch)200x200x11 mm (approx. 8x8 inch)200x200x11 mm (approx. 8x8 inch)200x200x11 mm (approx. 8x8 inch)200x200x11 mm (approx. 8x8 inch)300x300x12 mm (approx. 12x12 inch)300x300x11 mm (approx. 12x12 inch)300x300x11 mm (approx. 12x12 inch)300x300x11 mm (approx. 12x12 inch)300x300x11 mm (approx. 12x12 inch)300x300x11 mm (approx. 12x12 inch)500x500x12 mm (approx. 20x20 inch)500x500x11 mm (approx. 20x20 inch)500x500x11 mm (approx. 20x20 inch)500x500x11 mm (approx. 20x20 inch)500x500x11 mm (approx. 20x20 inch)500x500x11 mm (approx. 20x20 inch)1000x1000x12 mm (approx. 40x40 inch)1000x1000x11 mm (approx. 40x40 inch)1000x1000x11 mm (approx. 40x40 inch)1000x1000x11 mm (approx. 40x40 inch)1000x1000x11 mm (approx. 40x40 inch)1000x1000x11 mm (approx. 40x40 inch)Calibration will be performed on a Perkin Elmer Lambda 950, data will be supplied electronicallyin 1 nm steps, 50 nm step printed documentation with NIST/PTB traceability with certificate forthe 250 nm – 2450 nm range.Typical Reflectance - Zenith Lite Diffuse Reflectance Targets100%90%80%70%% 00175020002250Wavelength (nm)5% Target10% Target20% Target50% Target90% Target95% TargetZenith Polymer Full Material TargetsAlthough the Zenith Lite diffuse targets cover a wide range of applications, in some cases, the purity of the material and volume reflection (bulk scattering) is required.
