產品概覽

  • 遠心鏡頭在各種工作距離內會產生不變的放大倍率
  • 在產生 1% 的圖像比例誤差之前允許物件移動 ±12.5mm
  • 供應其他透鏡轉換器

遠心鏡頭在各種工作距離內會產生不變的放大倍率,幾乎消除了視角誤差。55mm焦距遠心鏡頭在圖像比例發生1%的誤差前允許物件移動±12.5mm(於0.5X放大倍率下)。相同條件下,傳統鏡頭通常允許±1.7mm的移動。需要取下鏡頭的保護視窗(於C接口端)以用於轉接鏡頭。

這些鏡頭極其適合需要準確測量具有細微高度差異的三維物件的機器視覺應用中。透過消除傳統鏡頭固有的透視畸變和放大倍率誤差,它們可產生尺寸上準確、軟體能夠輕易解析的圖像。

要安裝這些鏡頭,建議使用工業用調整架和安裝轉接器作為工作站平台。由於前群調焦,環形光導管不能直接安裝於此鏡頭上。
