Infinity Optical Systems - From “Infinity Optics” to the Infinity Port

“Infinity Optics” is the concept of a light path with parallel rays between the objective and tube lens of a microscope [1]. Placing flat optical components into this “infinity space” which do not influence image formation is critical for contrast methods, like DIC or fluorescence, often used for scientific applications. The addition of instruments, such as light sources or laser devices, into the infinite light path is required. Different approaches to fulfill this need are described here.

By examining a sample’s color, birefringence, and other optical properties, additional information about its structure, material properties, and composition can be obtained.

Biomarker Discovery with Laser Microdissection

Explore the potential of spatial proteomics workflows, such as Deep Visual Proteomics (DVP), to decipher pathology mechanisms and uncover druggable targets. Altered protein expression, abundance, or activity can significantly impact cellular function—often contributing to disease. Remarkably, the proteome can vary dramatically between neighboring cells. Spatial proteomics accounts for this cellular heterogeneity to reveal pathological mechanisms. Laser Microdissection (LMD) enables access to single cells for downstream analysis while preserving their spatial context—forming the foundation of spatial proteomics.

Key Questions

1What is your application?

The Leica compound light microscope you need depends on your application. The demands of different applications are best met by different light microscopes and light microscope parts. The modular design of Leica light microscopes enable a customized solution to be set up for a specific application.

2Which type of samples do you need to visualize?

Whether you are observing samples for routine laboratory work, materials production or analysis, or complex life science research, the optical resolution, contrast, depth of field, and image quality you need are provided by Leica light microscope solutions. Additionally, light microscope parts and accessories, such as objectives, illumination types, and digital cameras, along with the Leica Application Suite software, can further customize and optimize the solution for your specific application needs.

3What about the budget for the light microscope solution?

Customized light microscope solutions can lead to higher investment costs, but they allow you and your colleagues to increase productivity. A microscope solution can be optimized essentially for almost any application due to a large variety of light microscopes, light microscope parts, and accessories.

4What is the difference between a compound light microscope and stereo microscope?

A compound light and stereo microscope both use optics with an objective lens and eyepieces or oculars for viewing the image of the sample. In general, a compound light microscope achieves a higher range of magnification than a stereo. There is only one light channel for viewing the sample with a compound microscope, so a 2D image is seen. A stereo microscope has two light channels, one for each eye of the observer, which enable a 3D image of the sample to be seen. If either a compound or stereo microscope is equipped with a camera, then just one light channel is used and only a 2D image can be recorded.

A compound microscope uses optics to produce a magnified image of a sample so that with details of it can be observed that are undetectable with the naked eye. The most basic optics of a compound microscope has at least 2 lenses: i) an objective placed nearby the sample which creates a magnified, real image of it and ii) eyepieces or oculars which are used to view the real image of the sample. A human who looks through the eyepieces sees the sample as a virtual image on his/her retina. For more information, please refer to the Science Lab article: Optical Microscopes – Some Basics

The maximum useful magnification value achieved with any type of light microscope depends on its ultimate resolving power or maximal resolution. The resolution depends on the microscope objective lens numerical aperture (NA). At low magnification values, the NA is small leading to a low resolution. At high magnification values, the NA is high yielding a high resolution. However, because the NA has a finite maximum value, approximately 1.3, the “useful” range of magnification is limited to about 1,800x for conventional light microscopes. Magnification beyond the useful range, which can occur whenever digital microscope cameras display images on large monitors, is called "empty” magnification. In this non-useful magnification range, the sample structures appear larger, but no additional details are resolved. For more information, please refer to the Science Lab articles: Beware of "Empty" Magnification, What Does 30,000:1 Magnification Really Mean?
