特征透射、反射波长标准物质

波长标定,您还在用汞灯吗?

无论是光谱仪、分光光度计,无论是反射还是透射,

现在您只需一块波长标准板!!

无需电源、无需维护,操作简便-----直接放入样品室即可!

稀有元素的氧化物在紫外、可见及近红外光区有特定的吸收峰,可用于光谱仪、分光光度计等光谱仪器的波长标定,我们提供的氧化钬玻璃滤光片及氧化铷镨混合物滤光片就是可以用于波长标定。这些波长标定的滤光片都追溯NRC标准。

WCT-2065 Wavelength calibration Standard


The transmittance version of the standard, designated at WCT-2065, is the equivalent of NIST SRM-2065. The filter is currently available in 20 mm and 25.4 mm diameter configurations. This standard is extremely useful in the calibration of NIR spectrophotometers, both dispersive and Fourier transform, in the 400-2200 nm wavelength range. The filter material is glass made with a combination of rare earth oxides, including holmium oxide, samarium oxide, ytterbium oxide, and neodymium oxide in a base glass containing oxides of lanthanum, boron, silicon, and zirconium.

The reflectance version of the standard, designated WCR-2066, is the equivalent of NIST SRM-206. The standard is ideal for calibration of the wavelength scale of both scanning and Fourier transform near-infrared spectrometers used in the reflectance configuration. The standard consists of a 1.0” diameter WCT-2065 filter backed with Avian Technologies Fluorilon™ FW-99 diffuse reflectance material, in a black anodized aluminum holder designed to fit most spectrometers. This standard is useable in the 320-2200 nm range.

Description

WC-PP-1920a-01
WC-PP-1920a-02
Identical to NIST SRM-1920a, this standard is a mixture of highly purified holmium oxide, dysprosium oxide, and erbium oxide in a hermetically sealed black anodized aluminum holder with either 2" (52mm) or 1.5" (37 mm) optical glass window. The standards are made in large batches and each batch is calibrated traceable to NIST/NRC.
EWC-P1920a-02c EWC-P1920a-02c compliments the encapsulated gray scale standards . The wavelength standard has the same components as the National Institute of Technology’s SRM-1920a, with a small amount of an inert, spectrally non-absorbing binder. Unlike sintered equivalents of SRM-1920a, this standard exhibits no peak shifting and is both durable and stable. The spectral features are the same as WC-PP-1920a
WCR-2066-025C (Calibrated)
WCR-2066-025U (Uncalibrated)
The reflectance version of the transmittance wavelength calibration standard, is the equivalent of NIST SRM-2036. The standard is ideal for calibration of the wavelength scale of both scanning and Fourier transform near-infrared spectrometers used in the reflectance configuration. The standard consists of a 1.0” diameter WCT-2065 filter backed with Avian Technologies Fluorilon™ FW-99 diffuse reflectance material, in a black anodized aluminum holder designed to fit most spectrometers. This standard is usable in the 320-2200 nm range.
