M Plan Apo 1X Objective Lens (Brightfield, Ultra-Wide Field Overview)
The M Plan Apo 1X is a precision 1x microscope objective designed for brightfield observation across the visible spectrum. Ideal for overview inspection, sample positioning, and imaging large areas, this objective provides an exceptionally wide field of view while maintaining stable focus thanks to its very large depth of field.
With an infinity-corrected optical design and wavelength correction from 436–656 nm, the M Plan Apo 1X delivers consistent imaging performance for general observation and documentation. Its wide viewing capability allows a field of view of up to ø24 mm using a ø24 mm eyepiece, making it a strong choice for fast inspection and alignment tasks.
Compatible with VMU / FS-70 / MF-U / Hyper MF-U microscope systems, the M Plan Apo 1X is an excellent low-magnification option for wide-area brightfield observation.
Note: To avoid optical flare when using coaxial illumination, 1x objectives should be used together with a polarisation unit and an attached 1/4 wavelength plate.
