A-Plan – the A class

A-Plan objectives from Carl Zeiss offer sound and reasonably priced entry into the world of microscopy. They are versatile in their use and deliver good optical quality.

Plan-APOCHROMAT – the precision performers

With the best color correction and highest numerical apertures, Plan-APOCHROMAT objectives deliver brilliant images in brightfield, DIC and fluorescence techniques. Their outstanding point spread function and extreme chromatic correction are particularly impressive. High resolution and excellent image sharpness make even the finest details and color nuances visible.

EC Plan-NEOFLUAR – the all-round performers

Where flexibility and multiple imaging methods are required, the EC Plan-NEOFLUAR objectives are often selected. The optimized IC2S optics makes it possible to achieve contrast rich imaging with excellent homogeneity and high resolution. From transmission to the near UV, outstanding flatness of field and achromatic correction, to high numerical apertures, the EC Plan-NEOFLUAR class meets the high demands of applications using brightfield, darkfield, phase contrast, DIC, polarization and fluorescence.

LD Plan-APOCHROMAT 20x/1.0

Now, for the first time, you can observe neuron networks in brains that are fully intact: the new objective LD Plan-APOCHROMAT 20x/1.0 lets you penetrate into tissue to a depth of up to almost six millimeters and image your sample with excellent sub-cellular resolution using the Scale clearing method.


The LD C-APOCHROMAT objective has a long working distance while retaining a high numerical aperture of 1.1. It is particularly suited to fulfill your demands in confocal multiphoton microscopy, which extremely high penetration depths are achieved through the use of infrared excitation light. However, it is also possible to achieve excellent results with this objective using other 3D techniques such as ApoTome Structured Illumination and 3D Deconvolution.


The FLUAR objectives stand for maximum light transmission and photon collection. Manufactured from special glass, these objectives have been developed specifically for qualitative and quantitative analyses of ion modifications and for demanding fluorescence applications. Good flatness of field up to 23 mm, high numerical apertures and very high transmission from a wavelength of 340 nm – making even the weakest signals clearly visible.

LCI – the immersion specialists

LCI stands for Live Cell Imaging. The high-performance objectives of this class have been specifically developed for complex applications involving living cells and tissues. They are calculated for temperature intervals of 23º C to 37º C. Spherical aberrations caused by deviating cover slip thicknesses, different temperatures or refractive indices are ideally compensated by use of correction collar. Therefore, more visible details and reliable results for your scientific analyses are possible.
