Lasers find widespread applications, commonly employed to either (1) heat material onto a base or (2) ablate material off of a base. Laser ablation systems necessitate the integration of microscope components due to the precise manipulation of the laser beam, including focusing, bending, and reducing scattering. Typically, a laser ablation setup incorporates custom optics instead of off-the-shelf components, with the laser intricately designed into the system, as illustrated in Figure 14. The laser is strategically oriented in an epi-illumination design to leverage the microscope objective’s capacity to focus light at the object plane, generating exceptionally small spot sizes with minimal aberrations. Additionally, an eyepiece enables the user to visually locate the laser and ensure proper functionality. Filters are indispensable in shielding the user’s eyes from potential laser damage. Laser ablation setups, known for their superior precision compared to traditional surgical methods, find applications in medical and biological contexts.

A microscope is an optical device designed to magnify the image of an object, enabling details indiscernible to the human eye to be differentiated. A microscope may project the image onto the human eye or onto a camera or video device.

There are two major specifications for a microscope: the magnification power and the resolution. The magnification tells us how much larger the image is made to appear. The resolution tells us how far away two points must be to be distinguishable. The smaller the resolution, the larger the resolving power of the microscope. The highest resolution you can get with a light microscope is 0.2 um, but this depends on the quality of both the objective and eyepiece.

In the following content, we delve intensively into the various components and features of microscope objective lenses, exploring their construction, functionality, and specialized designs that enable researchers to gain deeper insights into the microscopic world.

The chromatic aberration of the three wavelengths, with a slight chromatic aberration remaining in the purple, and the curvature of the field have been corrected. Also called fluorite.

Confocal microscopy offers the capability to capture sharp images from a slender slice of a dense sample, minimizing background noise and reducing out-of-focus disturbances. Optical sectioning, widely employed in biomedical science and materials science, involves placing a sample on the microscope stage. An image is initially acquired at the primary focal plane, and subsequently, the stage or objective is adjusted vertically to capture images at successive focal planes.

It is suitable for inspection photography because it focuses not only on the center of the field of view but also on the periphery, producing a flat image.

For brightfield illumination to be effective, there needs to be a variation in opacity across the object. Without this variation, the illumination creates a dark blur around the object, resulting in an image with relative contrast between the object’s parts and the light source. Typically, brightfield illumination allows clear visualization of each part of the object unless it is extremely transparent. In cases where transparency hinders feature distinction, darkfield illumination becomes useful.

Fluorescence microscopy is a powerful imaging technique used primarily in biomedical research to visualize and study samples labeled with fluorescent dyes or proteins at the microscopic level. The method relies on the phenomenon of fluorescence, where materials absorb light at a specific wavelength (excitation light) and then emit light at a longer wavelength (emission wavelength). A focused light source, such as a laser, is used to selectively excite fluorescent molecules within the sample. The emitted fluorescence is captured to form detailed images, providing valuable information about the sample’s internal structure and composition.

This is the most common method, but if you focus on the center of the field of view, the periphery becomes blurred, so it is not suitable for inspection photography.

Epi-illumination, a third form of illumination employed in microscopy, generates light from above the objective. This setup replaces the need for a Koehler illumination configuration, as both the objective and the epi-illumination source contribute to the illumination process. The compact structure  of epi-illumination is a significant advantage, as the objective serves as a primary source for a considerable portion of the illumination. Figure 4 provides a depiction of a frequently used epi-illumination setup, particularly common in fluorescence applications.

Both the objective lens and the eyepiece also contribute to the overall magnification of the system. If an objective lens magnifies the object by 10x and the eyepiece by 2x, the microscope will magnify the object by 20 times. If the microscope lens magnifies the object by 10x and the eyepiece by 10x, the microscope will magnify the object by 100x. This multiplicative relationship is the key to the power of microscopes, and the prime reason they perform so much better than simply magnifying glasses.

Although today’s microscopes are usually far more powerful than the microscopes used historically, they are used for much the same purpose: viewing objects that would otherwise be indiscernible to the human eye.  Here we’ll start with a basic compound microscope and go on to explore the components and function of larger more complex microscopes. We’ll also take an in-depth look at one of the key parts of a microscope, the objective lens.

In modern microscopes, neither the eyepiece nor the microscope objective is a simple lens. Instead, a combination of carefully chosen optical components work together to create a high quality magnified image. A basic compound microscope can magnify up to about 1000x. If you need higher magnification, you may wish to use an electron microscope, which can magnify up to a million times.

In many microscopes, backlight illumination is favored over traditional direct light illumination due to the latter’s tendency to over-saturate the object under inspection. One specific backlight illumination technique employed in microscopy is Koehler illumination. This method involves flooding the object with light from behind using incident light from a source like a light bulb (see Figure 2). Koehler illumination utilizes two convex lenses, the collector lens and the condenser lens(or called field lens) , to ensure even and bright illumination on both the object and image planes. This design prevents imaging the light bulb filament, a common issue with direct light illumination. Backlight illumination is also commonly referred to as brightfield illumination.

Darkfield illumination directs light rays obliquely onto the object, avoiding direct entry into the objective. Despite this oblique angle, the rays still illuminate the object plane. The resulting darkfield illumination image achieves high contrast between the transparent object and the light source. In a darkfield setup, a light source forms an inverted cone of light that blocks central rays but allows oblique rays to illuminate the object (see Figure 3). This design effectively forces light to illuminate the object without entering the optical system, making darkfield illumination particularly suitable for transparent objects. In contrast, no rays are blocked in a brightfield illumination setup.

Microscope objectives are pivotal components in optical microscopy, especially in influencing image quality and resolution. Selecting the right objective is crucial for achieving optimal results in your microscopy applications. To guide you through the selection process, consider the following factors:

Microscope objective lenses, vital optical elements in microscopy, enable precise observation of specimens. Objective lens manufacturers offer a wide range of objective designs for specific needs: high power for detailed observation, scanning for broader views, oil immersion for high-resolution imaging, and long working distance for manipulation without compromising quality. Those objectives are designed with advanced construction techniques for high performance objectives with a spring loaded retractable nose cone assembly that protects the front lens elements and the specimen from collision damage.

A basic compound microscope could consist of just two elements acting in relay, the objective and the eyepiece. The objective relays a real image to the eyepiece, while magnifying that image anywhere from 4-100x.  The eyepiece magnifies the real image received typically by another 10x, and conveys a virtual image to the sensor.
