产品系列说明

2mm 到 200mm 尺寸的圆形和方形版本可选
7 种宽带增透镀膜可选
业内最全标准N-Bk7 窗口片可选
另有超薄 N-BK7 窗口片可供选择

TECHSPEC® λ/4 N-BK7精密窗口片非常适合用于工业及低功率激光应用。其高精度设计使得窗口片甚少发生波束畸变与散射的情况。宽带镀膜选项让可见光和近红外光谱产品方面的精密窗口片选择变得更为广泛。TECHSPEC® λ/4 N-BK7 精密窗口片提供从 2 毫米到 200 毫米不等的圆形和矩形尺寸。

请注意: 该产品系列的新产品可以用透射波前畸变（TWD）规格而不是表面平整度来指定。关于这两种规格之间的区别的更多信息，请参见我们的应用说明：了解光学窗口片。
