近紅外(NIR)線性偏振膜
近(jin)紅外(NIR)線(xian)性偏(pian)(pian)振(zhen)膜(mo)由耐用(yong)的(de)(de)聚合物基片組成,特別適合從(cong)可見光(guang)(guang)(guang)到(dao)近紅外(wai)(400-2200nm)的(de)(de)成像(xiang)應用(yong)。該偏(pian)(pian)振(zhen)聚合物薄膜(mo)的(de)(de)平(ping)均透射率為39%,在(zai)760和2200nm的(de)(de)入射隨機偏(pian)(pian)振(zhen)光(guang)(guang)(guang)下的(de)(de)偏(pian)(pian)振(zhen)效率大(da)于(yu)99.6%。多種矩形尺寸可用(yong)于(yu)容納(na)從(cong)光(guang)(guang)(guang)束直徑(jing)較小(xiao)的(de)(de)低功率NIR激(ji)光(guang)(guang)(guang)器到(dao)較大(da)LED光(guang)(guang)(guang)束的(de)(de)所有光(guang)(guang)(guang)源。近紅外(wai)(NIR)線(xian)性偏(pian)(pian)振(zhen)膜(mo)用(yong)于(yu)工業(ye)成像(xiang)和實驗室(shi)應用(yong),即減低輸(shu)出近紅外(wai)激(ji)光(guang)(guang)(guang)器和LED的(de)(de)強度,或減少(shao)近紅外(wai)光(guang)(guang)(guang)電(dian)檢測(ce)器記(ji)錄的(de)(de)圖像(xiang)中(zhong)的(de)(de)眩光(guang)(guang)(guang)。偏(pian)(pian)振(zhen)軸標記(ji)在(zai)偏(pian)(pian)振(zhen)聚合物膜(mo)的(de)(de)保護(hu)性擋板上(shang)。
注意:在第一次使用(yong)前(qian),請(qing)移除保護罩。

高對比度近紅外(NIR)偏光膜
高對比(bi)度近紅(hong)外(NIR)偏(pian)光(guang)(guang)(guang)膜在(zai)可見(jian)光(guang)(guang)(guang)和(he)近(jin)紅(hong)外光(guang)(guang)(guang)譜(pu)中可提供出色的(de)對比(bi)度(du),是傳統玻璃(li)偏(pian)光(guang)(guang)(guang)片(pian)的(de)經濟型替代品。這些(xie)偏(pian)光(guang)(guang)(guang)膜設計(ji)用于在(zai)工(gong)業成(cheng)像(xiang)應用中通過近(jin)紅(hong)外光(guang)(guang)(guang)電(dian)探測(ce)器幫助管理雜散光(guang)(guang)(guang)和(he)減少眩(xuan)光(guang)(guang)(guang)。這些(xie)偏(pian)光(guang)(guang)(guang)膜在(zai)近(jin)紅(hong)外波長下(xia)的(de)對比(bi)度(du)為1,000:1,在(zai)可見(jian)光(guang)(guang)(guang)下(xia)的(de)對比(bi)度(du)為10,000:1,因此具有優異(yi)的(de)寬帶性能。高對比(bi)度(du)近(jin)紅(hong)外(NIR)偏(pian)光(guang)(guang)(guang)膜在(zai)415-1600nm之間(jian)具有高透過率,并且可以很輕松進行尺寸切割。這些(xie)偏(pian)振膜是用于傳感、近(jin)紅(hong)外成(cheng)像(xiang)和(he)短波紅(hong)外應用的(de)理想選擇。
