Avian Technologies提供四种稀土氧化物玻璃滤光片:氧化钬玻璃、氧化镝玻璃、复合氧化物滤光片和长波滤光片。所有滤光片都有可用于紫外-可见-近红外光谱特征峰;氧化二钇通常用于光谱的可见区域,而多氧化物、氧化钬和长波滤光片则用于整个紫外-可见-近红外范围。

复合氧化物滤光片 (WCT-2065)

Avian Technologies与 NIST 的分析化学部门合作,为可见-近红外光谱提供波长校准标准。

WCT-2065 相当于NIST SRM-2065。本标准适用于校准 400-2200 nm 波长范围内的近红外分光光度计,包括光栅光谱仪 和 傅里叶变换光谱仪。该滤光片标准是在含有镧、硼、硅和锆氧化物的基础玻璃中加入稀土氧化物(包括氧化钬、氧化钐、氧化镱和氧化钕)而组合制成的玻璃。

该材料也可制作成反射型的波长标准。
