Lenses for video projectors are normally designed and manufactured for each projector. Although some manuafacturers such as Sanyo, Barco and NEC make large projectors with interchangeable lenses, the lenses are still made for specific models. There is no standard for lens mounts as yet and it is unlikely that there will be a standard in the near future.
What else can I help you with?
Which lens is used in projector?
since you need to show the image on a big screen so you require a diverging lens i.e. a concave lens
What kind of image can a concave lens produce?
A concave lens produces a virtual, upright, and diminished image. The image appears on the same side as the object and cannot be projected onto a screen. This type of lens diverges light rays, causing them to spread out, which creates the characteristic virtual image. Concave lenses are commonly used in applications like glasses for nearsightedness.
Where should an object be placed in front of a convex lens to get a real image of the size of the objects?
The object should be placed beyond the focal point of the convex lens to obtain a real image of the same size as the object. This distance is greater than the focal length of the lens, and the image will be inverted. Placing the object closer to the lens will produce a virtual image that is larger than the object.
Eyepiece lens function?
used to focus the image
What is the property of image formed by concave lens?
Image formed by a concave lens or a diverging lens is virtual,upright and smaller than the object.It is used by short sighted people.
Which type of mirror used in looking glass?
A magnifying glass is actually a convex LENS. The object you are looking at is closer to the lens but pass the focal point therefore you create an imaginary image that is larger than the actual object. An imaginary image is an image that you cannot focus on a screen.
What is the role of lenses used in cameras telescopes and microscopes?
In a simple microscope, a lens magnifies the image of the sample. in a compound microscope, the objective lens magnifies the image (there may be more than one objective lens) and the eyepiece lens enlarges the virtual image (which is typically inverted by the objective lens).
What is the objective lens used for?
The objective lens is used in optical instruments such as microscopes and telescopes to gather and focus light onto the image plane. It plays a critical role in determining the magnification and resolution of the final image.
What is objective lens used for?
The objective lens focuses and magnifies the object and transmits this image into the body tube of the microscope.
Why does a microscope use a convex lens?
A convex lens is used in a microscope to magnify the image of the specimen being examined. The shape of the lens allows it to focus light rays and produce a larger, clearer image for observation.
Where is an image produced by a lens form?
An image produced by a lens is formed where all the light rays converge or appear to diverge. This point is known as the focal point or focal plane, depending on the type of lens used.
What is overhead projector and projector?
An overhead projector is used to project an image of a transparency onto a wall or screen by means of an overhead mirror. There are also "slide projectors" that are used to display photographic slides on a wall or screen. A "projector" or "digital projector" would be used similar to a computer monitor or a television screen that would display an inputted image from a variety of sources (blu-ray player, computer, laptop, dvd players, game console, etc.). In the case of a projector the image is projected with the help of a light apparatus shining through a small silicon ship and projected through a lens to create an image on your wall or projector screen.
