Alluxa高性能濾光片以先進(jìn)的設(shè)計(jì)工藝和鍍膜過程控制,使Alluxa濾光片具有行業(yè)內(nèi)*的透過率,*的截至深度和波長(zhǎng)精確性,其中通過SIRRUS™離子束沉積硬鍍膜技術(shù),也使得Alluxa濾光片具有使用壽命長(zhǎng),高損傷閾值,以及*的批次穩(wěn)定性等特點(diǎn),并已經(jīng)廣泛應(yīng)用于生物熒光系統(tǒng)、拉曼系統(tǒng)、量子、雷達(dá)通訊等精密光學(xué)系統(tǒng)中.
Alluxa除了豐富的標(biāo)準(zhǔn)品,同時(shí)提供定制服務(wù),并且定制成本在行業(yè)內(nèi)有相當(dāng)大的競(jìng)爭(zhēng)力.
Alluxa超窄帶通濾光片介紹
圖1.具有OD6阻斷的超窄帶濾波器，用于1064 nm Nd：YAG激光器。憑借業(yè)界可達(dá)0.1nm的帶寬和高達(dá)98%的透過率，Alluxa的薄膜超窄帶帶通濾光片將優(yōu)化基于激光的系統(tǒng)的性能。
超窄濾光片非常適合用作激光線，激光清除或激光激發(fā)濾光片，適用于熒光顯微鏡，流式細(xì)胞儀和DNA測(cè)序等應(yīng)用。它們對(duì)激光損傷也很有抵抗力，可確保它們長(zhǎng)時(shí)間保持高水平的性能。
根據(jù)系統(tǒng)的波長(zhǎng)范圍和要求，Alluxa窄帶干涉濾波器可以定制設(shè)計(jì)，以滿足以下一個(gè)或多個(gè)具有挑戰(zhàn)性的規(guī)范：
? 峰值傳輸率高達(dá)98％
? Up to 98% peak transmission
? 通過設(shè)計(jì)達(dá)截至深度高達(dá)OD10
? Up to OD10 blocking by design
? 波長(zhǎng)范圍250nm～1800nm可選
? CWL at any wavelength from the UV to the near IR (～250nm to 1800nm)
? CWL中心波長(zhǎng)精度可達(dá)0.05nm
? CWL tolerances as tight as 0.05nm
? FWHM帶寬可達(dá)0.1nm
? FWHM bandwidths as narrow as0.1nm
? 透過波前差(RMS)：極優(yōu)0.01λper inch @ 632.8nm
? TWE as low as 0.01 wave RMS/inch measured at 632.8nm
精密控制用的Flat-top
圖2.具有陡峭邊緣，深度阻擋和方形光譜形狀的平頂超窄帶通濾光片。Flat-top,超窄的帶通濾波器特別設(shè)計(jì)，在整個(gè)通帶中有極陡的邊緣和高透過率。這個(gè)正方形的光譜形狀可以達(dá)到0.1 nm的帶寬。Flat-top窄帶濾波器是理想的激光雷達(dá)、拉曼光譜和其他需要使用精密激光發(fā)射濾波器或激光清理過濾器的理想選擇。
創(chuàng)新的薄膜涂層工藝的質(zhì)量和一致性
圖3. ULTRA系列濾光片的波長(zhǎng)控制，傳輸和截至在幾種不同的涂層運(yùn)行中具有高度可重復(fù)性。Alluxa薄膜光學(xué)干涉濾光片和介質(zhì)鏡均采用我們的SIRRUS™等離子沉積工藝在我們團(tuán)隊(duì)設(shè)計(jì)和制造的設(shè)備上進(jìn)行硬涂層。這使我們能夠在幾種不同的涂層上可靠，重復(fù)地生產(chǎn)相同的高性能光學(xué)薄膜，從而在所有系統(tǒng)中實(shí)現(xiàn)一致的性能。
