Ray Optics And Optical Instruments Class 12 Notes Pdf Download
the human eye. Microscopes are used to observe the shape of bacteria, fungi, parasites and host cells in various stained and unstained preparations. There are many different microscopes available. This guide provides: A brief background on microscopes and microscopy (Chapters 2Œ4). How to maintain a microscope in good condition. Chapters 5Œ • Ray Optics of the Optical Microscope All microscopes are similar in the way lenses work and they all suffer from the same limitations and problems. 2. Magnification is a function of the number of lenses. Resolution is a function of the ability of a lens to gather. with foundations in optical theory but extensions into electronic imaging. Accordingly, the cover shows the conjugate field and aperture planes of the light microscope under the title “Fundamentals of Light Microscopy and Electronic Imaging.” The book covers three areas: optical principles involved in diffraction and image.

The incident ray, normal microscope optics pdf download reflected ray all lie in the same plane. The angle of incidence is always equal to angle of reflection. All the distance measurements are done from pole of the mirror and height measurements are from the principal axis. The distances measured in the direction of incident ray are positive and in opposite direction of incident ray are negative. The heights measured upwards from principal axis are positive and downwards negative.
If m is positive then the image is virtual and erect. If m is negative then the image is real and inverted, microscope optics pdf download. The incident ray, normal and refracted ray all lie in the same plane, microscope optics pdf download. The ratio of sine of angle of incidence and sine of angle of refraction is constant for a given pair of media.
The ratio of sine of angle of incidence and sine of angle of microscope optics pdf download is the refractive index of refracting medium with respect microscope optics pdf download the incident medium.
The relative refractive index of medium 2 w. The light must propagate from optically denser medium to optically rarer medium. The angle of incidence in the denser medium must be greater than critical angle of incidence for the given pair of media. This phenomenon is called Total internal reflection. Brilliance of diamond, totally reflecting prisms, Mirage, Looming, Optical Fibre. When microscope optics pdf download falls on a convex refracting surface, it bends and the relation between U, V and R is given by.
Intensity of scattered light is. Sky is blue. Sun is reddish at the time of sunrise and sunset 3. Infra-red photography used in foggy days. Orange colour of black Box 5. Yellow light used in vehicles on foggy days. Red light used in signals. Resolving power of microscope is the ability of the microscope to show as separate images of two point objects lying close to each other.

Zeiss's 'Microscopy from the very beginning' is another excellent introduction to modern microscopy (note: download the pdf brochure). Looking for advice on cleaning your microscope's optics? First, see the excellent page here. Remember though that the cement used in microscope optics changed greatly over the years and you should definitely. with foundations in optical theory but extensions into electronic imaging. Accordingly, the cover shows the conjugate field and aperture planes of the light microscope under the title “Fundamentals of Light Microscopy and Electronic Imaging.” The book covers three areas: optical principles involved in diffraction and image. Microscope Optics The statement by Ernst Leitz in , “With the User, For the User,” describes the fruitful collaboration with end users and driving force of innovation at Leica Microsystems. We have developed five brand values to live up to this tradition: Pioneering, High-end Quality, Team Spirit.
