梯度折射率 (grin) 柱鏡梯度折射率透鏡（GRIN）的特點(diǎn)就是通過改變材料的折射率來聚焦。本品沒有復(fù)雜的幾何形狀（比如非球面面型就很復(fù)雜），也不需要進(jìn)行特別的設(shè)計(jì)，不用確定工作距離，在光學(xué)系統(tǒng)中使用非常方便。
這種梯度折射率透鏡的數(shù)值孔徑是0.55，有兩種工作距離可選，0mm工作距離版本適合于光纖和激光管的光束準(zhǔn)直，因?yàn)檫@種鏡片可定位并直接粘接在發(fā)射源上。也可用于聚焦，也可以應(yīng)用在一些鏡片不能直接固定在發(fā)射源的場合，本系列所有產(chǎn)品可選小工作距離。每種版本的可選未鍍膜版（大約12%的反射損耗），或鍍有寬帶增透膜的版本，鍍膜版的再設(shè)計(jì)波長處平均反射率<0.5%。
