Depending on the camera used, the internal zoom of the camera can be used up to 75% of the zoom range allowing you to reframe and get tighter shots without having to remove the wide angle lens.

Spherical Lens is a piece of transparent optical material with two spherical surfaces to refract light rays. They either converge or diverge light rays to form an image. Spherical Lenses can be classified into major types namely

Tired of screwing on wide lenses? Use the AOI Quick Release Adapter to easily take the lens on and off with a push of a button and a quarter turn. The kits below include the lens and port adapters.

Ans. The focal length can be defined as the distance of the Principal Focus from the optical center of a lens. Focal length is denoted by f and is measured in meters (m).

The Backscatter M52 wide angle wet lens was designed with the Olympus TG series 1 through 7 of cameras in mind. With a 120 degree angle of coverage, sharp corners, and no vignetting at 24mm this lens is the perfect combination for the first time wide angle shooter with a TG camera.

Magnification formula forconvexlens

A positive (+) sign of magnification indicates that the image is virtual and erect, whereas a negative (-) sign indicates that the image is real and inverted.

Example: What is the distance of the image from the lens if the object is 6 cm away from a convex lens of focal length 3 cm?

This O-ring kit eliminates burping the UWL-M52 lens underwater on your TG camera housing. It allows you to pre-seal water from a rinse bucket and eliminates the need to unthread the lens underwater to “burp” it. This O-ring set lets you shoot split shots (over/under) with a wet lens on your TG housing. These O-rings are not compatible with the QRS system.

Here, v is the distance of the image from the lens, u is the distance of the object from the lens, and f is the focal length of the lens.

The Backscatter M52 wide angle wet lens is one of the smallest lenses out there for the angle it covers. It comes with a neoprene dome cover, rear lens cap, and custom fit Backscatter hardshell travel case.

Example: What will be the height of the image if the object distance is 20 cm, the image distance is 60 cm, and the height of the object is 5 cm?

The lens threads directly on to any Olympus TG series 1 through 6 housing, no adapters required. There is an ergonomically placed silicone grip for easy threading. The lens shade has a smooth and easy rotation with the perfect balance between tension and maneuverability, with no tools needed.

Ans. Both real and virtual images are formed by convex lenses, therefore the convex lens can produce either positive or negative. Real images always have negative Magnification whereas virtual images always have positive Magnification.

Lens is a part of a transparent thick glass bounded by two spherical surfaces. Spherical Lenses are optical instruments that cause light rays to converge or diverge depending on the type. Spherical lenses are divided into two types namely Concave Lens and Convex Lens.

The Backscatter M52 wide angle wet lens was designed to be used with 24mm equivalent cameras. Other lenses wide angle wet lenses vignette (dark or clipped corners) at 24mm that require zooming to eliminate and have blurry corners. Our lens has no vignetting at 24mm and sharp corners.

The Backscatter M52 wide angle wet lens was designed with the Olympus TG series 1 through 7 of cameras in mind. With a 120 degree angle of coverage, sharp corners, and no vignetting at 24mm this lens is the perfect combination for the first-time wide angle shooter with a TG camera.

Ans. The lens formula is applicable in all situations related to spherical lenses with appropriate sign conventions. Thus, the lens formula is used to find the distance of an image whether it is a real or virtual image.

Shipwrecks, stingrays, sharks, reefs, divers. These are the subjects where you need a wide angle lens. Getting wider allows you to get closer to your subject while still maintaining a wide field of view and increases clarity and contrast of your image.

The SI unit of Power of a Lens is Dioptre represented by the letter 'D'. A lens with a focal length of one meter has a power of one dioptre. Convex lenses have positive power, while concave lenses have negative power.

Magnificationof convexlensis positive or negative

Magnification of a lens is the ratio of the height of the image formed by the lens to the height of the object. Magnification is equal to the ratio of the image distance to that of the distance of the object. It is denoted by m. The formula of magnification using lens formula is:

Lens Formula is an equation that gives the relationship between the focal length, image distance, and object distance. Lens Formula is given as

Ans. Object Distance is the distance of the object which is measured from the optical center of the lens. The distance of an object from the optical center is called object distance. The object distance is denoted by u.

Ans. Magnification is defined as the ratio of the height of the image height to the height of the object. In other words, it is the ratio of image distance to object distance. Magnification is denoted by the letter 'm'. The formula to find the magnification of a lens is given as follows:

Magnification formulabiology

Lens formula can be used in all situations related to spherical mirrors with appropriate sign conventions. The images which are formed by the Concave and the Convex lens can be real or virtual as well as they may have different sizes.

Power of a Lens is the degree of convergence or divergence of the light rays falling on a lens. The degree of convergence or divergence of the light rays depends upon the focal length of the lens. The power of the concave lens is negative, whereas the power of the convex lens can be positive. Therefore, the power of a lens is the reciprocal of the focal length of the lens used.

Magnification formula for lensin terms of focal length

Lens Formula states the relationship between the distance of an object, the distance of an image, and the focal length of the lens in Optics. Lens formula is applicable to both concave and convex lenses. It is used to find image distance for both real images or virtual images.

Ans. Power of a Lens is defined as the measure of the degree of divergence or convergence of a beam of light caused by a lens. The convergence and divergence of a lens are determined by the focal length of a lens. Thus, the power of a lens is reciprocal to its focal length.
