LCTR-M is a lens decentering measurement device. This instrument can calculate the "shift" and "tilt" of lens decentering from the lens R, allowing measurement of lenses with an aperture between approximately ø8 mm and ø120 mm.
A high degree of accuracy up to 10" has been achieved. (However, instrument resolution differs depending on the lens R.) The measurement accuracy is further increased with a 3-step variable power system, enabling easy observation as well.)
A built-in variable power system has improved operability. Additionally, the adoption of a 3-point controller mechanism has drastically facilitated rotation of the lens or frame.
Alleviated operator's fatigue
The operator's fatigue involved in visual observation has been alleviated through the use of a video monitor.
Easy confirmation of working distance
A working distance can easily be confirmed by sliding the illuminator lens in accordance with a measured R.
