The diameter of the view field in an optical microscope is termed the field number and represents the diameter of the field measured in millimeters at the intermediate image plane. This interactive tutorial explores the effect of varying the field of view size on the viewable specimen area.

The Eclipse Ti2 inverted microscope delivers an unparalleled 25mm field of view (FOV) that revolutionizes the way you see.

Infrared waves usesin medicine

Answer 1: Radiation is generally famous for causing cellular damage. However, Infrared radiation is not potent enough to cause the development of malignancy. But, studies show that this radiation can reduce the efficiency of DNA  repair as a result of increased skin temperature. In some rare cases, there have been signs of discrepancy in the skin thickness which happens due to Infrared radiation exposure.

The transmission of data through infrared rays is quite common in the communication of the short-range. We utilize the light-emitting diodes for emitting this radiation. Further, the focus is done on a narrow beam with the support of a plastic lens. At the end of the receiver, the photo-diode converts radiations into electric current.

Answer 3: One of the most common examples of Infrared is the heat of the Sunlight. Interestingly even the heat produced from radiators, fireplace etc are also Infrared radiation. The most common aspect of Infrared radiation is that it raises the surface temperature of the body.

Infrared radiations are also known as thermal or heat waves. The range of wavelength is between 710 mm to 1 mm. The rays also characterize as near and far-infrared rays. The near-infrared rays have use in photography and TV remote sensor.

If an auxiliary lens is inserted between the objective and eyepiece, the magnification factor of this lens should also be employed in the equation by multiplication with the objective magnification (prior to the division operation). Although the field number is usually limited by the magnification and field diaphragm (stop) size of the eyepiece, there is clearly a limit that is also imposed by the design of the objective lens system. In early microscope objectives, the maximum usable field diameter tended to be about 18 millimeters or considerably less, but with modern plan apochromats and other specialized flat-field objectives, the maximum usable field can sometimes exceed 26 millimeters. Correspondingly, the field of view through microscope camera ports has risen in step with larger objective field numbers and larger camera sensors. The Nikon Eclipse Ti2 inverted microscope in particular offers a 25mm field of view through the camera ports.

Infrared radiation is a part of the electromagnetic spectrum. Moreover, the spectrum includes other radiations from radio waves to X-rays. The radiation is characterized by wavelength. Thus, the x-rays, gamma, and ultraviolet are of short wavelength with high energy and quite dangerous. The infrared, radio waves and microwave are of longer wavelength and less harmful. Therefore, in this article, we are going to be discussing in detail this radiation in detail.

However there was a marked change that went beyond the final color red on the visible spectrum. Moreover, this change denotes as Infrared as it occurs at a frequency between visible red light and invisible microwave.

Nikon offers a range of eyepiece options featuring magnification and field of view combinations tailored towards a variety of applications.

Far infrared rays are thermal. The human body also generates heat or infrared radiation of approximately 800 nm wavelength.

World-class Nikon objectives, including renowned CFI60 infinity optics, deliver brilliant images of breathtaking sharpness and clarity, from ultra-low to the highest magnifications.

Answer 2: No, both of them are entirely different. While red light is visible to naked eyes, Infrared light is not. We cannot feel the red light on the skin. However, since Infrared light generates heat, there will be a sensation of temperature rise on the skin when we expose it to Infrared.

In most cases, the eyepiece field diaphragm opening diameter determines the view field size. The field size in the specimen plane is then defined as the field number divided by the magnification of the objective:

British Astronomer, William Herschel first introduced this term to the board of Scientist in 1800 using a simple experiment with thermometer. As the thermometer was placed in the path of light, the colors of the spectrum showed temperature change.

The tutorial initializes with a randomly selected specimen visible in the virtual microscope viewport and the field number set to a value of 20. Use the Field of View slider to adjust the field size between 10 and 28 millimeters, and note how the viewable specimen area increases or decreases with the field number. After viewing a specimen, use the Choose A Specimen pull-down menu to select another specimen.
