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).
