精密吸收性中性密度(ND)滤光片
?传输波前畸变为λ/4
?针对450-700nm范围采用增透膜
?提供的光学密度介于0.1至4.0之间
?另外提供吸收性中性密度(ND)滤光片
精密吸收性中性密度(ND)滤光片采用 SCHOTT NG 彩色玻璃基片，经过抛光可实现 λ/4 的传输波前畸变 (TWFD)。这些滤光片的两个表面都镀有 450 - 700nm 的增透 (AR) 膜，从而减少了背向反射，并降低了滤光片堆叠的损耗和伪影。精密吸收性中性密度 (ND) 滤光片能提供从 0.1 到 4.0 的光学密度，可以进行堆叠以实现定制的光学密度，从而满足应用要求。这些中性密度滤光片具有 25mm 直径或 50mm 的方形尺寸，非常适用于机器视觉、成像或低功率激光应用。

采用增透 (AR) 膜的 HOYA 吸收性中性密度 (ND) 滤光片
采用增透 (AR) 膜的 HOYA 吸收性中性密度 (ND) 滤光片使用 HOYA 彩色玻璃基片，其两面都具有增透膜，以减少可见光或近红外 (NIR) 范围内的背反射。VIS 0°、NIR I 和 NIR II 宽带增透膜分别涵盖 425-675nm、600-1050nm 和 750-1550nm 的光谱范围。这些中性密度滤光片能通过吸收来衰减光，可以堆叠在一起以实现定制的光学密度，从而满足应用需求。采用增透 (AR) 膜的 HOYA 吸收性中性密度 (ND) 滤光片非常适合在成像和检测应用中用于减少杂散光，以及在一般滤光片堆叠应用中用于控制强度。12.5、25 和 50mm 标准公制直径与我们台式应用的
TECHSPEC? C、S 及 T 接口圆形光学元件安装座兼容。
