NA2徠卡水準(zhǔn)儀
| |||||
| 徠卡的光學(xué)品質(zhì)使NA2和NAK2給用戶們留下鮮明印象： | |||||
 | 按鍵進(jìn)行補(bǔ)償器檢查 | ||||
| 無(wú)限位螺旋 | ||||
| 粗精調(diào)焦旋鈕 | ||||
| 自由旋轉(zhuǎn)腳螺旋 | ||||
| 可選目鏡 | ||||
| 的光學(xué)器件 | ||||
| 為提高精度，能在望遠(yuǎn)鏡物鏡內(nèi)安置一個(gè)測(cè)微計(jì)。測(cè)微計(jì)能讀至0.1mm，估讀至0.01mm。這使NA2和NAK2成為變形觀測(cè)和工業(yè)測(cè)量的高精度的理想儀器。 NAK2型號(hào)內(nèi)部有玻璃圓圈供讀取水平角。依據(jù)水準(zhǔn)尺讀數(shù)可計(jì)算出視距。 | |||||
