愛特蒙特遠心度測試板

在測量成像系統固有的角度誤差大小時，遠心度是非常有用的測量方式。藉由確定遠心度，使用者可以計算成像系統的最大測量精度。此測試板可用於校準遠心與非遠心鏡頭中的遠心度。運用該測試板，梯形畸變將變為可見，並且可以使用軟體進行測量。Lenses from our 0.08X MVO® Telecentric Lens (#56-948) to the 5X Mitutoyo Telecentric Objective (#56-986), and any lens in between, including our high resolution Double Gauss lenses, VZM™ Zoom Lenses, and MVO® MMS® interchangeable lens system, can be calibrated or compared with this target.
