反射型波長標準

波長標定,您還在用汞燈嗎?

無論是光譜儀、分光光度計,無論是反射還是透射,

現在您只需一塊波長標準板!!

無需電源、無需維護,操作簡便-----直接放入樣品室即可!

稀有元素的氧化物在紫外、可見及近紅外光區有特定的吸收峰,可用于光譜儀、分光光度計等光譜儀器的波長標定,我們提供的氧化鈥玻璃濾光片及氧化銣鐠混合物濾光片就是可以用于波長標定。這些波長標定的濾光片都追溯NRC標準。

Avian Technologies的稀土氧化物波長校準標準在大部分紫外-可見-近紅外光譜范圍內顯示出清晰的吸收峰,專門設計用于校準紫外-可見-近紅外光譜儀。選擇不同稀土氧化物的混合物,實現在不同波段范圍內的最佳覆蓋。

我們提供三種稀土氧化物標準:

壓制粉末包裝的波長標準

本標準是一種高純度氧化鈥、氧化鏑和氧化鉺的混合物,置于一個密封的黑色陽極氧化鋁護套中,帶有2 inch(52mm)或1.5 inch(37mm)的光學玻璃窗口。該標準與NIST NIST SRM-1920a*的成分相同。標準品是大批量生產的,每批都經過校準,可追溯至NIST/NRC。

玻璃封裝可見近紅外標準板

本標準封裝形式與我們玻璃封裝灰階標準相同,可以作為組合套裝出售。該標準的成分與NIST NIST SRM-1920a*相同,含有少量惰性、對光不吸收的粘合劑,封裝在密封的Delrin 護套中。與SRM-1920a的燒結等效物不同,本標準沒有峰值偏移,且耐用且穩定。光譜特征與我們的粉末壓制波長校準標準相同。該標準還有兩個擴展版本,添加了滑石粉或聚苯乙烯窗口,以提供更長波長范圍內的額外特征峰。

波長反射標準

透射波長標準的反射率相當于NIST SRM-2036。本標準適用于校準使用反射光路的掃描光譜儀和傅里葉變換近紅外光譜儀的波長精度。該標準由一個直徑為1.0 inch 的 WCT-2065 濾光片 與背后的 Fluorilon™ FW-99漫反射材料組成。本標準可在320-2200 nm 范圍內使用,可選校準認證證書。

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.
