225型NOVA真空紫外(VUV)單色儀可被用于任意空間位置和角度. 除光柵板外, 所有可動部件都在外面, 以便于調(diào)節(jié)。其焦距為1.0 米,正入射, 除光柵外不需其它光學(xué)部件。選用適當(dāng)?shù)墓鈻疟井a(chǎn)品可用于波長在30 到1200 納米之間。它帶有水平狹縫,其開口率為f /10.4, 和56 x 96 毫米光柵。1200 G/mm 光柵精度為±0.1 納米。采用精確正弦驅(qū)動掃瞄調(diào)節(jié)的外聚焦,如果需要,客戶可以選用我們的步進(jìn)電機(jī)控制聚焦。產(chǎn)品無需內(nèi)部支撐結(jié)構(gòu),完全用不銹鋼內(nèi)焊制成。二個標(biāo)準(zhǔn)狹縫裝配有雙邊可調(diào)整的狹縫調(diào)節(jié)裝置以及隔離閥、進(jìn)氣口和粗調(diào)閥。
本產(chǎn)品也可裝備雙光柵支架,以同時使用兩個光柵。
購買本產(chǎn)品通常需要同時選購光柵及支架,步進(jìn)驅(qū)動系統(tǒng)、真空泵和工作臺。
如果另外選購側(cè)面狹縫, 則需同時購買進(jìn)口和出口狹縫以及可折疊的反射鏡。
