全息衍射光栅
Spectrum Scientific的全息光栅是采用干涉光刻法制造的。这个过程获得光滑的凹槽表面并消除在刻线光栅中存在的周期性误差。因此，全息光栅通常用于对杂散光敏感的应用中。全息光栅可以采用两种凹槽轮廓，正弦和闪耀。
正弦凹槽轮廓是全息光栅的最常见的凹槽形状。凹槽是对称的，因此没有闪耀方向。与闪耀光栅相比，正弦光栅提供更宽的光谱覆盖，但效率较低。
Spectrum Scientific是世界上少数几家提供闪耀全息衍射光栅的公司之一。闪耀全息光栅具有变换成“锯齿”轮廓的正弦轮廓。该锯齿轮廓在不增加杂散光的情况下，在感兴趣的波长区域内提高衍射光栅的效率。目前这种技术限于200-300mm的闪耀区域。
Spectrum Scientific提供一系列标准光栅。如果我们没有满足您的要求的光栅，请联系我们的销售部门定制。
