1、總覽
Sciencetech為研究應(yīng)用提供了多種弧光燈源。短弧燈是高壓放電燈。這些燈因其高輻射和高亮度而特別適合于光學(xué)應(yīng)用。放電電弧在兩個(gè)電極之間自由燃燒產(chǎn)生光。電弧的長(zhǎng)度取決于兩個(gè)電極之間的距離，通常只有幾毫米。這使得弧光燈成為理想的點(diǎn)光源。
這本小冊(cè)子重點(diǎn)介紹了Sciencetech的氙弧燈光源，燈殼內(nèi)充滿高壓氙氣，可提供廣泛的照明波長(zhǎng)。
您可以從第4頁(yè)的便捷包裝中選擇一種（包括光學(xué)器件，外殼，燈泡和電源以及所有互連），也可以從我們的模塊化組件中構(gòu)建自己的組件，從而**滿足您的要求。設(shè)計(jì)為可在垂直或水平模式下運(yùn)行，并且隨附有用于兩個(gè)方向的基板。在下面的配置部分中，根據(jù)反射器類型（準(zhǔn)直輸出為球形，聚焦光束為橢圓形）和所需的弧光燈選擇外殼，并添加兼容的電源和燈。**后，添加適合您的應(yīng)用的光學(xué)器件。有關(guān)一些預(yù)配置的軟件包，請(qǐng)參見(jiàn)手冊(cè)。
