Spach Optics stocks microscope objectives from all four major manufacturers — Olympus (Evident), Nikon, Zeiss, and Leica — plus Leitz, Wild, and Mitutoyo, so mixed-brand labs can source everything from a single supplier. Browse by correction type (plan achromat, plan fluorite, plan apochromat), immersion medium (air, oil, water dipping), or application, including fluorescence, confocal imaging, DIC, phase contrast, and semiconductor inspection. We carry both infinity-corrected and fixed tube length optics. Every objective is quality-verified before it ships — optics inspected for clarity, coating condition, and mechanical function — and most orders ship quickly from our US facility. University purchase orders welcome. Not sure which objective fits your microscope or thread standard? Call or email us — compatibility guidance is free.
