The diverging lens equation is a mathematical representation that connects the object distance (p), the image distance (q), and the focal length (f) of a lens. The equation is \[ \frac{1}{f} = \frac{1}{p} + \frac{1}{q} \].

A diverging lens, also known as a concave lens, diverges light rays travelling parallel to its axis, causing them to appear as if they're originating from a single point on the opposite side - this is known as the focal point. The unique shape of this lens causes light to bend away from the central axis.

Diverging lenses are used in corrective eyewear for individuals with myopia, or nearsightedness. They are also used in optical devices like telescopes and flashlights, and in various industries such as science, technology and even medical equipment.

The XBAR RGB provides uniform and powerful lighting in a variety of colours. It is a versatile product that is especially useful when controlling a wide range of colours, shapes, and materials. The XBAR RGB is equipped with a solid body made of anodised aluminium and can work in continuous or strobe mode. It is recommended for robotics applications, particularly the palletization process, as well as packaging inspection (for the cosmetics and food industries), where the product’s colours and materials may change on a regular basis.

Focal Length (f): The distance from the lens where parallel rays of light converge or appear to diverge after passing through the lens. It is negatively assigned to diverging lenses.

In the world of astronomy, the study of celestial bodies often relies on cutting-edge telescopes, many of which benefit from diverging lenses. The lens system in many of these telescopes is designed to combine the attributes of both converging and diverging lenses — enabling crisp, detailed views of faraway planets, stars, and galaxies. A deeper exploration of such a use of diverging lenses within telescopes could open up opportunities to understand not only the lenses themselves but also the intricate science behind these fascinating optical devices.

2020419 — A camera sensor and its size determines image size, depth of field, resolution, low-light performance, a camera's physical size, and more.

Image Distance (q): The distance from the lens to the image. It is negative if the image is virtual, as for the images formed by diverging lenses.

UV INFO: in the light spectrum, UV (ultra violet) rays are electromagnetic radiations situated between 280 and 400 nm (visible radiations: between 400 and 800 nm). What makes UV very interesting is the fact that, even if it is invisible for the naked eye, it can be observed by fluorescence: when some bodies are submitted to UV wavelengths, they emit a visible light. This is the principle of black light and of counterfeit notes detection.

Think of a beam of light travelling parallel to the lens's axis. This beam, upon hitting the lens, gets refracted away from the axis, appearing to originate from a specific point on the opposite side of the lens. That point is known as the focal point.

IP69K washdown backlight bars provide high brightness, highly diffuse illumination in a reliable package designed to withstand the rigours of harsh chemical cleaning & de-contamination.

Miniature modular bar light with built-in flexibility. The M-TBAR is a compact, IP67-rated tiny LED bar light that allows users to change the beam angle with TPL Vision’s Angle Changers. Offering unparalleled flexibility, the M-TBAR provides a convenient way to expertly illuminate small-scale vision applications requiring a robust lighting solution. Application areas include code reading, quality control, component verification, label- and packaging inspection, robotics and more.

The steps are: identify given parameters such as object distance (p), image distance (q), or focal length (f); substitute known values into the lensmaker's formula; solve for the unknown variable; and finally verify your answer, ensuring it makes sense within the context of the problem.

The Essential EBAR+ UV 405 is a highly powerful LED light, very useful for machine vision applications requiring intense luminous flux. It can be set up downwards, in the same axis as the camera’s, or with an angle of incidence, to perfectly illuminate rectangular areas on a production line.

The Essential EBAR+ UV 405 is very easy to use: you don’t have to adjust anything, only to plug it. There are 2 functioning modes: continuous and strobe, with very short rising and falling times (15 μs and 10 μs). Its black aluminum structure, very robust, is IP65. It also helps to dissipate the heat generated by the LED. Moreover, 2 LED indicators near the connector show if the product is powered.

A diverging lens produces a virtual, upright, and reduced image. It has a negative focal length and the images formed are found on the same side as the object.

Diverging Lens: A lens that diverges light rays that are travelling parallel to its axis, causing them to diverge as if from a single point on the opposite side of the lens.

Diverging lenses are used in door viewers or peepholes, which allow for a wide-angle view of the outside from a small point within a door.

One intriguing case is the inventive use of diverging lenses in certain types of peepholes or door viewers. These devices, installed in most residential apartments and hotel rooms, allow you to see the broader area outside your door from a small point within your door. The diverging lens inside the door viewer spreads out the light rays entering the peephole, offering a wide-angle view of the outside. Though the image produced is somewhat distorted and can appear smaller, it's a fascinating practical application of a diverging lens' property.
