100X DIN Semi-Plan, Finite Intl Standard Objective

Product Details For Use with RMS Thread Microscopes AR Coated Optics 4X to 100X Magnifications Available International Standard Microscope Objectives can be used with most major brands of microscopes that utilize RMS mounting threads. Our product offering features DIN 45mm standard objectives with achromatic and semi-plan designs. The achromatic design ensures proper color correction for broadband white light sources, while semi-plan designs have an added feature to create a flatter image field. International Standard Microscope Objectives include AR-coated optics to ensure maximum transmission and reduce internal reflections in the optical assembly. All 20X to 100X objectives have spring-loaded (retractable) front ends to prevent slide damage. Note: Oil immersion is recommended for all 100X objectives with an NA higher than 1.0 (part number #86-834 ).
