Here, we break down the anatomy of an objective lens into easy-to-understand terms and discuss the common parts that make up an objective.

In addition to these core components, some objectives include a spring-loaded retractable assembly to protect the front lens elements and specimen from collision damage.

Knowledge is power when it comes to objective lenses. Many objective designs require you to make a tradeoff in one area of performance when you improve another. However, advances in objective technology enable our latest optical designs to overcome this common limitation.

For instance, Olympus X Line objectives are packed with many ultra-thin convex and concave lenses to offer exceptional flatness, aberration correction, and numerical aperture in one lens system. The result? Bright, high-quality images throughout the field of view.

The objective lens is one of the most important parts of a microscope, since it determines its basic performance and function. Yet, these precision pieces of optical equipment are often not well understood.

While objective designs vary based on factors like their intended purpose, microscopy method, aberration correction, and manufacturer, all microscope objectives share some similar characteristics. Here are four common components to know:

Keep in mind, objectives with more optical corrections for aberrations and flatness typically contain many lenses. For instance, sophisticated plan-apochromatic objectives have about 15 lens elements—while common achromatic objectives contain significantly fewer lenses.
