詳細資料

TECHSPEC®硒化鋅(ZnSe)窗口片是廣泛紅外應用的理想選擇，包括用于熱成像、FLIR及醫療系統。它的吸收系數低，并對熱沖擊具有高度的抵抗性，因此這種氣相沉積材料在高功率二氧化碳激光系統中受到廣泛的使用。硒化鋅(ZnSe)是一種較易刮花的軟性材料，因此不適合在惡劣的環境中使用（努氏硬度僅為120）。處理時，必須施以一致的壓力，并且戴上乳膠指套或手套來防止污染。

注意: 在拿取硒化鋅時需要特別小心，因為其為有毒物質。在操作過程的全程都需要佩戴橡膠手套或塑料手套以避免接觸。

技術信息

AR COATED ZINC SELENIDE

Typical visible transmission of a 3mm thick ZnSe window coated with BBAR (1650-3000nm), BBAR (3000-12000nm), and BBAR (8000-12000nm coating).

This data is outside the design wavelength range of the BBAR coatings and thus is not guarenteed, but provides a reference for visible guide laser useage.

Typical transmission of a 3mm thick ZnSe window with BBAR (1650-3000nm) coating at 0° AOI.

The blue shaded region indicates the coating design wavelengh range, with the following specification: 

Ravg <1% @ 1650 - 3000nm
Rabs <2% @ 1650 - 3000nm

Data outside this range is not guaranteed and is for reference only.

Typical transmission of a 3mm thick ZnSe window with BBAR (3000-12000nm) coating at 0° AOI.

The blue shaded region indicates the coating design wavelengh range, with the following specification: 

Ravg <5.0% @ 3 - 12μm

Data outside this range is not guaranteed and is for reference only.

Typical transmission of a 3mm thick ZnSe window with BBAR (8000-12000nm) coating at 0° AOI.

The blue shaded region indicates the coating design wavelengh range, with the following specification: 

Ravg ≤0.5% @ 8 - 12μm

Data outside this range is not guaranteed and is for reference only.
