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.

There are many other potential uses for confocal microscopy, such as studying proteins, the structure of tissues, and the development of embryos.

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:

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.

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.

What is the maximum size of a specimen that can be studied with a confocal microscope? The maximum size of a specimen that you can study with a confocal microscope depends on the microscope’s resolution. The higher the resolution, the smaller the specimen that can be studied.

The future of confocal microscopy is bright. With the increasing resolution of confocal microscopes, there is no limit to the types of specimens studied with this technology. In addition, new software is being developed that can automatically analyze and process confocal images, making it easier to extract data from these images.

Studying thick specimens Confocal microscopy is ideal for studying thick specimens, such as tissue samples or embryos. This is because it can produce clear images of thick specimens without the need for sectioning.

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.

Confocal Microscopy is a type of optical microscopy that can be used to obtain a three-dimensional image of the object being studied. It has many uses in medicine, research, and industrial quality control. However, confocal scanning is technically demanding and expensive; it requires specialized equipment, limiting its use in some applications. The information about confocal microscopy explained in this article will give you a clear understanding of how this technology works and how it can be used in various fields.

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.

Low powerobjective microscopefunction

Confocal microscopy is an imaging technique that uses a laser to scan an object, providing a 3D image of the specimen. This type of microscopy is highly efficient in capturing sharp images of thick specimens while minimizing out-of-focus light. The technology works by creating a thin slice of the specimen and scanning it line-by-line. By doing this, the confocal microscope can create a three-dimensional image of the object being studied.

The basic principle behind confocal microscopy is to direct a laser beam at the specimen being studied. The laser beam is then reflected off the specimen and onto a detector. The light that is not scattered by the specimen is blocked by a pinhole, which helps to reduce out-of-focus light and produce a sharper image.

Studying the structure of cells Confocal microscopy is useful for studying the structure of cells, as it can produce high-quality images with little out-of-focus light.

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.

Achromatic objectives–This objective brings red and blue light to a common focus, and is corrected for spherical aberrations for green. It is excellent for black and white viewing. If an objective is not labeled, it is achromatic.

What is the difference between a confocal microscope and a traditional microscope? A confocal microscope uses a laser to scan an object, providing a three-dimensional specimen image. A traditional microscope uses light transmitted through the specimen to produce an image.

What is the minimum size of a specimen that can be studied with a confocal microscope? The minimum size of a specimen that can be studied with a confocal microscope depends on the wavelength of the laser used. The shorter the wavelength, the smaller the specimen that can be studied.

Where is the objective on a microscopediagram

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.

What is the resolution of a confocal microscope? The size of the pinhole determines the resolution of a confocal microscope. Therefore, the smaller the pinhole, the higher the resolution.

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.
