Another key area of research in quantum optics is the study of quantum entanglement. In this phenomenon, two or more particles become linked so that the state of one particle is correlated with the state of the other particle. This has significant implications for the development of secure communication channels and the study of fundamental physics.

Telecommunications is another discipline where physical optics is invaluable. The use of fiber-optic cables, which rely on the wave properties of light to transmit data, has revolutionized how we communicate.

The first image shows the eyepiece view when using a 1.0X objective with a 10X eyepiece. It has a 34mm field of view. The second image shows the video field of view of about 16–4.7mm (COLCAM-NTSC camera with a 0.5X coupler). The third image shows the video view that approximates the eyepiece view. It uses a 0.5X objective with a 20X eyepiece.

For instance, the ability to observe and manipulate light at the microscopic level has led to many important discoveries in biology and medicine.

Physical optics is also essential in the design of lasers, which are used in many applications, including surgery, materials processing, and communication.

Another key application of geometrical optics is optical lens design for vision problems such as nearsightedness, farsightedness, and astigmatism. These lenses work by bending light to compensate for the errors in the eye’s natural lens, allowing the person to see clearly.

Lastly, geometrical optics also plays an important role in the design of laser systems. By carefully controlling the direction and focus of laser beams, engineers can create highly precise and controlled cutting, welding, and drilling processes.

TIP: On the trinocular version of the PZMIII or PZMIV stereo microscope with the standard configuration (1.0X objective, 10X eyepieces) and with the optimal camera adaptor (0.5X on a ½” CCD camera) the video capture field of view is up to 40% less than the visual field. By using a 0.5X objective with 20X eyepieces the video capture area doubles, and the resulting video capture more closely matches the visual field of view.

Quantum optics is also used in studying systems such as quantum dots and nanocrystals, which have unique optical and electronic properties that make them useful for various electronics and materials science applications.

Problem: The PZMIII or PZMIV stereo zoom microscope normally comes with a 1.0X objective and a 10X pair of eyepieces. The magnification is 6X to 50X, however the concept of magnification is difficult to visualize. Let's discuss what can be seen at the two zoom extremes. Imagine the visual circle to be a range of 34–4.2 mm. This microscope has a working distance of 100mm. Researchers working with small animals will have difficulty working in this tight space.

If you’re in the market for high-quality optical lenses, consider Shanghai Optics. Our expert team of engineers and designers has years of experience creating custom-made lenses for various uses.

Starting the list is the branch of optics that deals with the wave properties of light, including its propagation, interference, diffraction, polarization, and scattering.

Objectivelens and eyepiece lens magnification

From the types of lenses in optics to laser technology and medical imaging, optics has revolutionized various fields of science and technology.

The design and development of many optical systems are possible because of geometrical optics. These include cameras, telescopes, and microscopes.

These technologies rely on the ability to manipulate and control individual quantum systems, such as single photons or atoms, to perform impossible tasks with classical systems.

One of the most significant of these is the development of quantum information technologies, such as quantum cryptography, quantum computing, and quantum teleportation.

NOTE: If a 1/3” inch camera (6mm diagonal) is used on the 0.5X microscope adaptor you can apply the ratio of 6/8 for the reduction in the captured field.

Plan objective–These objectives produces a flat image across the field of view. The three objectives discussed above all produce a curved image. A plan-achromat, plan-fluorite or plan-apochromat are corrected.

The term “optics” remains an important discipline in the world of physics. It embodies the study of light, its behaviors, and how it interacts with matter. There are many applications of optics, including telescopes and microscopes, laser technology, and medical imaging.

It explores the quantum nature of electromagnetic radiation and its interaction with matter, including atoms, molecules, and other quantum systems.

Apochromatic objective–This is the most expensive objective. It is chromatically adjusted for four colors (deep blue, blue, green and red) and spherically corrected for deep blue, blue and sometimes green. This is the best choice for color viewing. These have a higher numerical aperture (N.A.) than achromats or fluorites.

A variety of microscope objectives are available. All objectives use lenses to focus light. Light is broken down into various wavelengths (colors) as it travels through a lens. The various wavelengths have different focal points. That means that red, green and blue appears to focus at different points. This is called chromatic aberration. Spherical aberrations are focal mismatches caused by the shape of the lens. Quality lenses are designed correct for chromatic and spherical aberration to bring the primary colors to a common focal point. These terms may help you determine the best objective for your application:

Solution: Instead of the standard configuration, setup the microscope with a 0.5X objective to increase the working distance to 187 mm. The result of using this lower power objective is that the magnification range decreases by one half and at the same time the field of view double. To restore the microscope system to the original condition (magnification and field of view), replace the 10X eyepieces with 20X eyepieces. The use of these two options restores the visual field of view and magnification range back to the original condition with the added benefit of a larger working distance.

Infinity Correction–When measuring from the back end of the objective to the primary focal plane, many microscopes are limited to a specific distance (160mm). More expensive microscope use a different series of lenses, prisms and mirrors to allow for an "infinite" distance between those two points. This is called infinity correction.

Additionally, physical optics plays a critical role in the design of telescopes and other optical instruments in astronomy.

Fiber-optic communication uses thin fibers to transmit light over long distances. Engineers employ the principles of geometrical optics to design the fibers and ensure that the light travels efficiently and with minimal loss.

The last on the list is quantum optics. This branch of optics deals with the interaction between light and matter at the quantum level.

Fluorite or semi-apochromat objectives–These lenses are chromatically corrected for red and blue, and the green focus is also close. They are spherically corrected for blue and green. This objective is better suited for color viewing or recording than achromatic objectives.

In addition to these applications, physical optics is also essential in studying atmospheric optics, including phenomena such as rainbows, halos, and mirages. Physical optics is also used in the design of optical coatings and filters, which can control the transmission and reflection of light.
