Microscope Objective Lens Specification

Different Microscope Objective Lens Types

In general, when it comes to the microscopy lens types, we refer to the different magnification and uses of the four most commonly different microscope lenses on composite optical microscopes.

Scan the lens (4x)

The scanning objective is designed for getting bearings right before moving onto the low power lens.

Low-power lens (10 x)

The low-power microscope objective lens usually has 10x or 20x magnification. You can identify it by a yellow stripe around the lens housing. This objective can be very useful for viewing prepared specimens on slides.

High-power lens (40 x)

The high-power microscopy lens is applied for looking at smaller specimens like bacteria and cells that are invisible to the naked eye.

Oil-immersion lens (100 x)

These lenses are called ‘oil immersion lenses’ because you usually need to use them with oil in order to view your specimen.

Microscope Objective Working Distance

In general, the operating microscope objective working distance decreases with magnification and numerical aperture. Nowadays, the popular trend is to produce dry microscope objectives with as long working distances as possible, but this requirement is partly limited by a high numerical aperture that requires high resolution. This usually result in the manufacturers making a compromise between these two parameters.

To provide extensive optical solutions in machine vision optics systems, Canrill Optics, as a custom lens manufacturer, has been keeping developing, manufacturing and marketing telecentric lens for machine vision since 2009. In 2019 and 2020, Canrill Optics has successfully upgraded the telecentric lens to 4th generation PTL series and developed new series of non-telecentric Canrill lens.
