产品描述
用于低倍系统的多功能校准卡
1）可选新的毛玻璃版
2）校准系统倍率范围从0.08X到4X
3）可测MTF，视场，分辨率，景深，以及畸变
Ø附带NIST精度证明
本产品可用在倍率在0.08X到4X的测量仪器的系统校准，功能多样，使用一个卡就能够得出更多的参数。景深可由各种分辨率图组得到，可应用到各种特殊场合。系统传递函数可用频率为5lp/mm 到 80lp/mm线对的图案来测量。本测试图案包含两个外框，100 x 166 x 1.5mm，采用玻璃板上镀铬膜层，第二个板有个圆圈和栅格图案，可测量平面和斜面的畸变。可利用此图案的整个视场，在测不同的参数时无需挪动靶面，本品制作精度高，附带详细规格和认证。本品同时带操作卡，CD使用指南，以及包装箱，#58-770 有毛玻璃卡和标准玻璃镀铬卡。
