🔧 Product Description

The Zeiss A-Plan 2.5x objective delivers reliable optical performance for routine microscopy applications where cost-effectiveness is as important as image quality. A-Plan objectives provide achromatic correction, correcting for chromatic aberration at two wavelengths (red and blue) and spherical aberration at one wavelength, making them suitable for standard brightfield microscopy, phase contrast, and basic documentation tasks. At 2.5x magnification, this objective provides a wide field of view ideal for initial specimen screening, large-area tissue section imaging, and whole-slide overview before transitioning to higher magnifications. The 0.06 numerical aperture delivers adequate light-gathering capability and excellent depth of field for three-dimensional specimens and thick samples. The 10.4mm working distance accommodates standard microscope slides with coverslips and allows room for basic specimen manipulation. The M27 thread mount ensures compatibility with Zeiss Axio, Axioskop, and other infinity-corrected platforms. A-Plan objectives are the economical choice for educational laboratories, routine quality control, and applications where basic optical correction is sufficient for the task at hand, offering Zeiss build quality and reliability at an accessible price point.
