Edmund 21mm, 26mm, 27mm, 和 35mm 接触式分划板- 环形标度圆标尺
Radius Scale
Crosshair with Concentric Circles
Metric Concentric Squares
Protractor in Degrees
本品采用玻璃材料，比胶片式的稳定性要好很多，因为胶片式分划板会弯曲，变形，易折损。图案是在玻璃表面上沉积低反射的铬膜，对比度高，读数方便。图案标记在分划板的外部，因此在观测时标尺可直接接触被测物体，适用于调焦和精测量。本系列所有的分划板可用于6X 和 9X 比较仪。26mm和35mm直径版可用于Peak珠宝放大镜和Peak照明放大镜，请注意在选购带分划板的放大镜，需要考虑其视场范围，比如说12X比较仪需要用5/8" (16mm)的视场，如果需要全视场测量时就不能选用¾”(20mm)的标尺。
