Edmund 21mm, 26mm, 27mm, 和 35mm 接觸式分劃板- 環形標度圓標尺
Radius Scale
Crosshair with Concentric Circles
Metric Concentric Squares
Protractor in Degrees
本品采用玻璃材料，比膠片式的穩定性要好很多，因為膠片式分劃板會彎曲，變形，易折損。圖案是在玻璃表面上沉積低反射的鉻膜，對比度高，讀數方便。圖案標記在分劃板的外部，因此在觀測時標尺可直接接觸被測物體，適用于調焦和精測量。本系列所有的分劃板可用于6X 和 9X 比較儀。26mm和35mm直徑版可用于Peak珠寶放大鏡和Peak照明放大鏡，請注意在選購帶分劃板的放大鏡，需要考慮其視場范圍，比如說12X比較儀需要用5/8" (16mm)的視場，如果需要全視場測量時就不能選用?”(20mm)的標尺。
