These extended apochromat objectives offers a high numerical aperture (NA), wide homogenous image flatness, and 400 nm to 1000 nm chromatic aberration compensation. They enable high-resolution, bright image capture for a range of applications, including brightfield, fluorescence, and confocal super resolution microscopy.

The ocular lens is located at the top of the eyepiece tube where you position your eye during observation, while the objective lens is located closer to the sample. The ocular lens generally has a low magnification but works in combination with the objective lens to achieve greater magnification power. It magnifies the magnified image already captured by the objective lens. While the ocular lens focuses purely on magnification, the objective lens performs other functions, such as controlling the overall quality and clarity of the microscope image.

To clean a microscope objective lens, first remove the objective lens and place it on a flat surface with the front lens facing up. Use a blower to remove any particles without touching the lens. Then fold a piece of lens paper into a narrow triangular shape. Moisten the pointed end of the paper with small amount of lens cleaner and place it on the lens. Wipe the lens in a spiral cleaning motion starting from the lens’ center to the edge. Check your work for any remaining residue with an eyepiece or loupe. If needed, repeat this wiping process with a new lens paper until the lens is clean. Important: never wipe a dry lens, and avoid using abrasive or lint cloths and facial or lab tissues. Doing so can scratch the lens surface. Find more tips on objective lens cleaning in our blog post, 6 Tips to Properly Clean Immersion Oil off Your Objectives.

The maximum magnification scale of order that can be achieved is dependent on the limitations of the scientific instrument being used. For example, the maximum magnification of a light microscope is typically around 1000x, while electron microscopes can achieve magnifications of up to 1,000,000x.

The magnification scale of order is crucial in scientific research as it allows scientists to observe and measure objects or phenomena that are too small or too distant to be seen with the naked eye. It also enables them to accurately document and analyze their findings.
