CFI Achromat Series objective lenses. Correction for chromatic aberration in this series has been dramatically improved and is now at the same level as the CFI Plan Achromat Series. These CFI Achromat objectives were also corrected for spherical aberration and coma and image flatness across the 22mm field of view has been drastically improved. The result: truly exceptional quality for this class of objectives.

CFI Apochromat TIRF Series Objective Lenses. These microscope objectives have highest NA available using standard immersion oil and glass coverslips. Thanks to incredibly high NA, when used in TIRF, they provide the shallowest evanescent field possible with oil immersion lenses. ApoTIRF objectives provide chromatic correction from 435nm to an incredible 1064nm. In addition they have terrific IR throughput, facilitating the ability to image and trap single molecules in the same focus plane, as well as make a terrific choice for multi-photon applications. A world-first temperature-change correction ring is included in the 60x and 100x Apo TIRF oil objectives. Users can easily correct temperature-induced changes – from 23° C (room temperature) to 37° C (physiological temperature) – in the refractive index of the immersion oil that can cause spherical aberration.

CFI Plan Achromat Series objectives for phase contrast microscopy. Nikon’s CFI Plan Achromat series provides incredible image flatness over the entire 25mm field of view, with chromatic aberration corrected throughout the entire visible spectrum. With incredible image sharpness, these objectives can be used for laboratory work as well as exacting research. Crisp, clear images of unstained images is made possible.

The CFI Plan Apochromat VC series Objective Lenses are top performance objectives with perfect correction of chromatic aberrations in the visible light range and excellent resolution throughout the field of view. They are the perfect choice for multi-stained, fluorescence specimens and when using brightfield and DIC techniques. In addition to the correction range of the conventional Apochromat series (435-660nm), axial chromatic aberration has been corrected up to the violet range (405nm), making these objectives highly effective PA-GFP, as well as other photo-activation and photo-conversion proteins that activate at 405nm. CFI Plan Apochromat VC optics are an ideal choice for critical confocal work as well.
