The Brightfield Objective features include:
• 100% MADE IN JAPAN
• Computer-Aided-Design (CAD) objective
• Non-Infinity Corrected Tube Lens Design, F=160mm
• DIN Standard mounting thread is 0.7965”(20.1MM) diameter threads
• 36 TPI (Threads per inch), 55° Whitworth
• High quality optics designed by Meiji Techno Engineers
• Objectives composed of Numerous internal glass elements
• Corrected for flatness of field
• Uniform Quality and Glass formulations
• Corrected for most common optical artifacts such as coma, astigmatism, geometrical abberation
• Corrected for field curvature and spherical and chromatic aberration
• Corrected for more aberrations over wider fields, but image flare has been dramatically reduced
• Substantial increase in light transmission, yielding crisp and remarkably bright sharp images
