近紅外(NIR)線性偏振膜
近紅外(NIR)線性偏(pian)振(zhen)(zhen)(zhen)膜由耐用(yong)(yong)(yong)的(de)(de)(de)(de)聚合物基片組成,特別(bie)適合從(cong)(cong)可見光(guang)到近(jin)(jin)紅外(400-2200nm)的(de)(de)(de)(de)成像(xiang)應用(yong)(yong)(yong)。該偏(pian)振(zhen)(zhen)(zhen)聚合物薄膜的(de)(de)(de)(de)平均透射率為39%,在760和(he)2200nm的(de)(de)(de)(de)入射隨機偏(pian)振(zhen)(zhen)(zhen)光(guang)下的(de)(de)(de)(de)偏(pian)振(zhen)(zhen)(zhen)效率大(da)于99.6%。多(duo)種矩形尺寸可用(yong)(yong)(yong)于容納(na)從(cong)(cong)光(guang)束(shu)直徑(jing)較(jiao)小的(de)(de)(de)(de)低功率NIR激光(guang)器(qi)(qi)到較(jiao)大(da)LED光(guang)束(shu)的(de)(de)(de)(de)所有光(guang)源。近(jin)(jin)紅外(NIR)線性偏(pian)振(zhen)(zhen)(zhen)膜用(yong)(yong)(yong)于工業(ye)成像(xiang)和(he)實(shi)驗(yan)室應用(yong)(yong)(yong),即(ji)減(jian)低輸(shu)出(chu)近(jin)(jin)紅外激光(guang)器(qi)(qi)和(he)LED的(de)(de)(de)(de)強度,或減(jian)少近(jin)(jin)紅外光(guang)電檢測(ce)器(qi)(qi)記(ji)(ji)錄的(de)(de)(de)(de)圖像(xiang)中的(de)(de)(de)(de)眩光(guang)。偏(pian)振(zhen)(zhen)(zhen)軸標記(ji)(ji)在偏(pian)振(zhen)(zhen)(zhen)聚合物膜的(de)(de)(de)(de)保護性擋板上。

高對比度近紅外(NIR)偏光膜
高對比(bi)度近紅外(NIR)偏(pian)光(guang)(guang)(guang)(guang)(guang)膜(mo)(mo)在(zai)(zai)可見光(guang)(guang)(guang)(guang)(guang)和(he)(he)(he)近紅(hong)外(wai)光(guang)(guang)(guang)(guang)(guang)譜中可提(ti)供出色的(de)對比度(du),是(shi)傳統玻璃偏(pian)光(guang)(guang)(guang)(guang)(guang)片的(de)經濟型替代品。這些偏(pian)光(guang)(guang)(guang)(guang)(guang)膜(mo)(mo)設(she)計用(yong)于(yu)(yu)在(zai)(zai)工業成(cheng)像應用(yong)中通過近紅(hong)外(wai)光(guang)(guang)(guang)(guang)(guang)電探測器幫助管(guan)理雜(za)散光(guang)(guang)(guang)(guang)(guang)和(he)(he)(he)減少眩光(guang)(guang)(guang)(guang)(guang)。這些偏(pian)光(guang)(guang)(guang)(guang)(guang)膜(mo)(mo)在(zai)(zai)近紅(hong)外(wai)波(bo)長下的(de)對比度(du)為1,000:1,在(zai)(zai)可見光(guang)(guang)(guang)(guang)(guang)下的(de)對比度(du)為10,000:1,因此(ci)具有優異的(de)寬(kuan)帶性能。高對比度(du)近紅(hong)外(wai)(NIR)偏(pian)光(guang)(guang)(guang)(guang)(guang)膜(mo)(mo)在(zai)(zai)415-1600nm之間具有高透過率,并且可以很輕松進行尺(chi)寸(cun)切割(ge)。這些偏(pian)振膜(mo)(mo)是(shi)用(yong)于(yu)(yu)傳感、近紅(hong)外(wai)成(cheng)像和(he)(he)(he)短波(bo)紅(hong)外(wai)應用(yong)的(de)理想選擇。
