光功率計(jì)(光強(qiáng)度計(jì))選型指南
· 光電二管探頭: 這些探頭設(shè)計(jì)用于單色光源或近單色光源的功率測(cè)量,因?yàn)樗鼈兙哂胁ㄩL(zhǎng)相關(guān)響應(yīng)。這些探頭根據(jù)輸入光功率和波長(zhǎng)輸出電流。電流輸入到跨阻放大器中,該放大器輸出一個(gè)正比于輸入電流的電壓。
· 熱功率探頭: 這些熱電堆探頭由在超寬波長(zhǎng)范圍內(nèi)光譜響應(yīng)相對(duì)平坦的材料制成,它們適用于寬帶光源( 例如LED和SLD)的功率測(cè)量。熱功率探頭的輸出電壓與輸入光功率成正比。
· 熱釋電能量計(jì)探頭: 我們的熱釋電探頭通過熱釋電效應(yīng)產(chǎn)生一個(gè)輸出電壓,適合測(cè)量脈沖光源,重復(fù)率被探測(cè)器的時(shí)間常數(shù)限制。這些探頭輸出與輸入脈沖能量成正比的峰值電壓。
