Remark

*1: Simple Polarized Light Observation 
*2: When using the large frame STM7-LF/STM7-LFA, a specimen whose height is 100 mm or less can be placed at the position backward from the light axis by 180 mm or more. 
*3: With Objective Lenses for Metallurgical Microscope 
*4: With Objective Lenses for Measuring Microscope
