全息衍射光柵

Spectrum Scientific的全息光柵是采用干涉光刻法制造的。這個(gè)過(guò)程獲得光滑的凹槽表面并消除在刻線光柵中存在的周期性誤差。因此，全息光柵通常用于對(duì)雜散光敏感的應(yīng)用中。全息光柵可以采用兩種凹槽輪廓，正弦和閃耀。

正弦凹槽輪廓是全息光柵的zui常見(jiàn)的凹槽形狀。凹槽是對(duì)稱的，因此沒(méi)有閃耀方向。與閃耀光柵相比，正弦光柵提供更寬的光譜覆蓋，但效率較低。

Spectrum Scientific是世界上少數(shù)幾家提供閃耀全息衍射光柵的公司之一。閃耀全息光柵具有變換成 鋸齒 輪廓的正弦輪廓。該鋸齒輪廓在不增加雜散光的情況下，在感興趣的波長(zhǎng)區(qū)域內(nèi)提高衍射光柵的效率。目前這種技術(shù)限于200-300mm的閃耀區(qū)域。

Spectrum Scientific提供一系列標(biāo)準(zhǔn)光柵。如果我們沒(méi)有滿足您的要求的光柵，請(qǐng)的銷售部門定制。
