波长校准标准

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。

Avian Technologies的稀土氧化物波长校准标准在大部分紫外-可见-近红外光谱范围内显示出清晰的吸收峰，专门设计用于校准紫外-可见-近红外光谱仪。选择不同稀土氧化物的混合物，实现在不同波段范围内的最佳覆盖。

我们提供三种稀土氧化物标准：

压制粉末包装的波长标准

本标准是一种高纯度氧化钬、氧化镝和氧化铒的混合物，置于一个密封的黑色阳极氧化铝护套中，带有2 inch（52mm）或1.5 inch（37mm）的光学玻璃窗口。该标准与NIST NIST SRM-1920a*的成分相同。标准品是大批量生产的，每批都经过校准，可追溯至NIST/NRC。

玻璃封装可见近红外标准板

本标准封装形式与我们玻璃封装灰阶标准相同，可以作为组合套装出售。该标准的成分与NIST NIST SRM-1920a*相同，含有少量惰性、对光不吸收的粘合剂，封装在密封的Delrin 护套中。与SRM-1920a的烧结等效物不同，本标准没有峰值偏移，且耐用且稳定。光谱特征与我们的粉末压制波长校准标准相同。该标准还有两个扩展版本，添加了滑石粉或聚苯乙烯窗口，以提供更长波长范围内的额外特征峰。

波长反射标准

透射波长标准的反射率相当于NIST SRM-2036。本标准适用于校准使用反射光路的扫描光谱仪和傅里叶变换近红外光谱仪的波长精度。该标准由一个直径为1.0 inch 的 WCT-2065 滤光片与背后的 Fluorilon™ FW-99漫反射材料组成。本标准可在320-2200 nm 范围内使用，可选校准认证证书。

UV-Vis Calibration Standards

Avian Technologies UV-Vis Wavelength Calibration Standards are a mixture of holmium and erbium oxides in an inert, durable, spectrally neutral matrix. Calibrations are traceable to the National Research Council Canada (NRC) and NIST. These standards, calibrated from 250-850 nm, are ideal for the calibration of UV-Vis spectrophotometers.

Standards are available in 1.25″ (37mm) and 2.0″ (50.8mm) diameter sizes, and come in a Delrin holder with cover.

Near-Infrared Calibration Standards

Avian Technologies Near-Infrared Wavelength Calibration Standards are a mixture of dysprosium, holmium, and erbium oxides in an inert, durable, spectrally neutral matrix. Calibration is traceable to the NRC and NIST. These standards are ideal for calibration of Vis-NIR spectrophotometers.

Standards are available in 1.25″ (37 mm) and 2″ (51 mm”) diameter sizes, and come in a Delrin holder with cover.

Long Wavelength Calibration Standards

This Avian Technologies standard combines NIST 2065 glass (Avian Technologies WCT-2065) and polystyrene in a package with a Fluorilon-99W™ backing to give a wavelength standard with useable peaks beyond 2300 nm, to meet the calibration needs for modern portable near-infrared spectrometers.

The standard size is 1.25” diameter (0.950” active area), and is mounted in a Thorlabs MR1 filter mount with a 2” mounting post.. Full calibration data, traceable to NIST/NRC, is provided with each standard.
