ZEISS Objective A-Plan 40x/0.65 M27 (77615, 421060-9900-000)

ZEISS Objective A-Plan 40x/0.65 M27 (77615, 421060-9900-000)

The ZEISS A-Plan 40x/0.65 M27 objective is a high-contrast plan-achromatic lens designed for both routine and research microscopy. It provides 40x magnification with a numerical aperture of 0.65 and supports cover glass correction from 0 to 1.00 mm. The working distance is 0.45 mm.

A-Plan objectives offer an excellent alternative to Achroplan lenses, delivering sharp, high-contrast images across a field number of up to 23 mm. They are suitable for multiple contrast techniques, including brightfield, differential interference contrast (DIC), and fluorescence applications within the visible spectral range.
