特性· 30弧分的楔形窗口片· 可選未鍍膜或鍍四種增透膜之一的版本o 245 - 400 nm(-UV膜)o 350 - 700 nm(-A膜)o 650 - 1050 nm(-B膜)o 1050 - 1700 nm(-C膜)· 提供Ø1/2英寸、Ø1英寸、Ø1.5英寸和Ø2英寸的版本· 定制版本請聯(lián)系技術(shù)支持QXKJ提供這種楔形紫外熔融石英窗口片系列產(chǎn)品。這種楔形光學(xué)元件消除了干涉條紋圖樣，并且有助于避免腔反饋。窗口片用于保護(hù)激光輸出不受環(huán)境的影響，適用于光束采樣應(yīng)用。QXKJ也提供許多基底材料和鍍膜選項的平窗口片。紫外級熔融使用非常適用于需要比N-BK7在更深的紫外波段透過率更大的應(yīng)用。紫外熔融石英也比N-BK7對于給定波長提供更低折射率，更好的均勻度和更低的熱膨脹系數(shù)。這些窗口片可選擇未鍍膜(185 nm - 2.1 μm)或鍍有四種低損耗標(biāo)準(zhǔn)寬帶增透膜(BBAR) 之一的版本，增透膜鍍在兩個光學(xué)表面上。BBAR增透膜設(shè)計成以下范圍：245 - 400 nm (-UV), 350 - 700 nm (-A), 650 - 1050 nm (-B)或1050 - 1700 nm (-C)。雖然未鍍膜的窗口片具有每個表面4%的典型損耗，BBAR鍍膜將該損耗減小到在波長范圍上每個表面Ravg< 0.5% ，并且對于0°與30°之間的入射角提供良好性能。紫外熔融石英楔形窗口片，未鍍膜 Wedge Angle30 ± 10 arcminDiameter1/2" (12.7 mm)1" (25.4 mm)1.5" (38.1 mm)2" (50.8 mm)Diameter Tolerance+0.0 / -0.2 mm+0.0 / -0.1 mm+0.0 / -0.2 mmThickness3.0 mm5.0 mm4.0 mm12.0 mmThickness Tolerance±0.4 mm±0.2 mm±0.1 mmClear Aperture≥Ø11.43 mm≥Ø22.86 mm>Ø34.29 mm≥Ø45.72 mmSurface Flatnessa≤λ/20 Over Central Ø5 mm≤λ/10 Over Clear Aperture≤λ/20 Over Central Ø10 mm≤λ/10 Over Clear Aperture≤λ/2≤λ/20 Over Central Ø15 mm≤λ/10 Over Clear ApertureSurface Quality10-5 Scratch-Dig20-10 Scratch-Dig10-5 Scratch-DigWavelength Range185 nm - 2.1 μm (Uncoated) 楔形窗口片，紫外熔融石英，增透膜：245 - 400 nmWedge Angle30 ± 10 arcminDiameter1/2" (12.7 mm)1" (25.4 mm)1.5" (38.1 mm)2" (50.8 mm)Diameter Tolerance+0.0 / -0.2 mm+0.0 / -0.1 mm+0.0 / -0.2 mmThickness3.0 mm5.0 mm4.0 mm12.0 mmThickness Tolerance±0.1 mm±0.2 mm±0.1 mmClear Aperture>Ø11.43 mm>Ø22.86 mm>Ø34.29 mm≥Ø45.7 mmSurface Flatnessa≤λ/20 Over Central Ø5 mm≤λ/10 Over Clear Aperture≤λ/20 Over Central Ø10 mm≤λ/10 Over Clear Aperture≤λ/2≤λ/20 Over Central Ø15 mm≤λ/10 Over Clear ApertureSurface Quality20-10 Scratch-DigAR Coating Range245 - 400 nmReflectance over AR Coating RangeRavg < 0.5%楔形窗口片，紫外熔融石英，增透膜：350 - 700 nmWedge Angle30 ± 10 arcminDiameter1/2" (12.7 mm)1" (25.4 mm)1.5" (38.1 mm)2" (50.8 mm)Diameter Tolerance+0.0 / -0.2 mm+0.0 / -0.1 mm+0.0 / -0.2 mmThickness3.0 mm5.0 mm4.0 mm12.0 mmThickness Tolerance±0.1 mm±0.1 mm±0.2 mm±0.1 mmClear Aperture≥Ø11.43 mm≥Ø22.86 mm>Ø34.2 mm≥Ø45.72 mmSurface Flatnessa≤λ/20 Over Central Ø5 mm≤λ/10 Over Clear Aperture≤λ/20 Over Central Ø10 mm≤λ/10 Over Clear Aperture≤λ/2≤λ/20 Over Central Ø15 mm≤λ/10 Over Clear ApertureSurface Quality20-10 Scratch-DigAR Coating Range350 - 700 nmReflectance overAR Coating RangeRavg < 0.5%楔形窗口片，紫外熔融石英，增透膜：650 - 1050 nmWedge Angle30 ± 10 arcminDiameter1/2" (12.7 mm)1" (25.4 mm)1.5" (38.1 mm)2" (50.8 mm)Diameter Tolerance+0.0 / -0.2 mm+0.0 / -0.2 mm+0.0 / -0.1 mm+0.0 / -0.2 mmThickness3.0 mm5.0 mm4.0 mm12.0 mmThickness Tolerance±0.1 mm±0.1 mm±0.2 mm±0.1 mmClear Aperture≥Ø11.43 mm≥Ø22.86 mm>Ø34.2 mm≥Ø45.72 mmSurface Flatnessa≤λ/20 Over Central Ø5 mm≤λ/10 Over Clear Aperture≤λ/20 Over Central Ø10 mm≤λ/10 Over Clear Aperture≤λ/2≤λ/20 Over Central Ø15 mm≤λ/10 Over Clear ApertureSurface Quality20-10 Scratch-Dig
