Apochromatic Objectives are designed to refract the indexes of three wavelengths, or colors, of light the same. These objectives provide higher precision, spherical aberration correction, and almost always have a long working distance and a high numerical aperture (NA). Similar to achromatic objectives, apochromatic objectives suffer greatly from field curvature and distortion, worsening as the magnification increases.

The Saskatchewan Structural Sciences Centre's Laser Technology Laboratory was built to conduct research using ultrashort pulses from Ti-doped sapphire lasers and laser amplifiers. These devices were invented in the early 1980s and since then these sources of high power short duration laser pulses have been applied for fundamental research in physics, chemistry, biology, and engineering. The short and powerful laser pulses are particularly useful for studying of compounds with very short fluorescence lifetimes. This type of laser pulses give rise to non-linear optical phenomenon in the samples under investigation, which in their turn allow to optimize the sample imaging, and give access to new contrast mechanisms for microscopy imaging. Disciplines from life sciences, chemistry, physics, and engineering make use of this lab to achieve their research goals.

An achromatic (or achromat) objective is designed to limit the effects of chromatic & spherical aberration, in other words the incoming light rays are focused in the focal point. Achromatic lenses corrects for color, by bringing in two wavelengths (typically red and blue) into focus. The lack of a flat field of view and limited correction for chromatic aberration reduce the objectives performance. It has a flat field across the central 65% of the image of the field of view. It’s usually a pair of lenses.

Plan (or planar) objectives are the best quality objectives. They correct better color and field curvature than either the achromatic or semi-plan objective. Field curvature results when the off-axis image is unable to be brought into focus in a flat image plane, which results in a blurred image. Plan objectives display better and correct better with a flat field in the center, about 95% of the image. They also often have larger working distances.

Achromatic objectives are usually corrected for axial chromatic aberration at two wavelengths (red and blue) merging these rays into a single focal point. While apochromatic objectives are corrected for chromatic aberration at three wavelengths (red, blue and green) while being spherically corrected at two to three wavelengths.
