Zeiss Plan Apochromat 5x Objective

The Zeiss Plan Apochromat 5x objective represents the pinnacle of optical correction technology, delivering superior chromatic and spherical aberration correction for the most demanding imaging applications. Plan apochromat objectives correct for chromatic aberration across three wavelengths (red, green, blue) and spherical aberration at two wavelengths, ensuring color-accurate, high-contrast images with minimal optical artifacts. This level of correction is essential for critical color imaging, quantitative fluorescence microscopy, and applications where faithful color reproduction is paramount. The 5x magnification provides an optimal balance between field of view and resolution for screening large specimens, tissue sections, and multi-well plates. The 0.16 numerical aperture delivers adequate light-gathering capability for brightfield, DIC, and moderate-intensity fluorescence applications, while the 12.2mm working distance accommodates thick specimens, slides with coverslips, and allows room for environmental chambers or manipulation tools. The RMS thread mount ensures compatibility with a wide range of microscope platforms, and an M27 adapter is available upon request for Zeiss infinity-corrected systems. Plan apochromat objectives are the preferred choice for color-critical applications including histopathology, immunohistochemistry, and multi-color fluorescence imaging where accurate color representation is essential for diagnostic or analytical accuracy.
