a. On the handle part of the scope, white marking (yellow arrow) was attached. When we press down the zoom lever (red arrow) to the point of the marking, we can consistently fix the magnification rate as low power. When we press down the zoom lever to the bottom, we can consistently fix the magnification rate as the highest power. b. At the low power of ME-NBI, the Line Pitch of 5–2 (white arrow) can be dissected by LM-NBI. Namely, the resolution power was measured as 13.9 μm. c. At the resolution power of HM-NBI, the Line Pitch of 6–4 (yellow arrow) can be dissected by HM-NBI. Namely, the resolution power was measured as 5.6 μm
