How do you find the maximum magnifying power?
Solution : Here, `f = 5 cm, m = ? d = 25 cm`
Maximum magnifying power, `m = (1+(d)/(f)) = (1+(25)/(5)) = 6`. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
Which microscope can magnify up to approximately 400 times?

What is a Dissecting microscope (Stereo microscope)?
This is a type of digital optical microscope designed with a low magnification power (5x-250x), by use of light reflected from the surface of the specimen, and not the light reflected the specimen. Its primary role is for dissection of specimens and viewing and qualitatively analyzing the dissected samples.
What is a dual power microscope?
Dual Power Dissecting Microscope- It has a dual-powered dissecting microscope of 10x and 30x, with a 360° rotation ability, for focussing and viewing. They have a dual objective pair, parfocalled, parcentered, and achromatic. Rotating the lenses allows a change of image magnification. It also uses a high LED intensity light ring which fills the surface with light. With a flexible stand, it can be lifted head high for viewing larger specimens.
What is a stereo zoom microscope?
Stereo Zoom Dissecting Microscope- They are trinocular or binocular dissecting microscopes with a zooming range of 6.7x-45x. They can be attached to the digital camera which takes photos of the viewing images. They have a dual-LED illuminator and they can rotate at 360°. Magnification can be changed by adding auxiliary objectives or different eyepieces.
How does a dissecting microscope work?
The dissecting microscope works with two magnification systems: Fixed (primary) magnification where two objective lenses provide a degree of magnification and the Zoom (pancratic) magnification which offers a continuous magnification at variant ranges, using the auxiliary objectives whose function is to increase total magnification depending on some factors. The variance between the zoom and the fixed magnification can be achieved by changing the eyepiece lenses.
How many eyepieces are there in a microscope?
Eyepieces- They have two eyepieces each focusing different pathways of the light into and out of the specimen, each with its own magnification power. To increase the magnification, the use of auxiliary eyepieces can be used.
What magnification is a single power stereo microscope?
Single Power Stereo Dissection Microscope- they have very low magnification power ranging from 10x-40x with inclined eyepieces at 45°C. they also have diopter adjustments of 50mm to 70mm.
What is the working principle of a dissecting microscope?
The working principle of the dissecting Microscope depends on the two types of light paths used by the microscope’s objectives and eyepiece. Each light path provides a different angle of viewing. They have the top light which is used while dissecting and the bottom light that is used to view the images.
