Optic lens to collimate/focus light from a LED.

In summary, the conversation is about finding a lens that can collimate or focus light from a LED with a focal length of over 500mm and an angle smaller than 1 degree. The option of a collimator or a focused lens is discussed, with the suggestion of using a 10-30mm focal length lens and considering the thin lens equation.

Hello.

I'm looking for a lens that can collimate (or focus far away >500mm ) a light coming out from a LED.

before I give more details is this even possible?

Thanks.

Take a pick, do you want it collimated or focused?

if the focused focal is far away it doesn't matter, I just looking for divergent/convergent angle smaller to 1 degree.

but if you want a pick let's said collimator.

A point source at the focal distance of a lens will produce a parallel beam out. So you want a 10-30mm focal length lens.

You need the thin lens equation.

Hello, thank you for your question. Yes, it is possible to use an optic lens to collimate or focus light from a LED. Optic lenses are designed to manipulate light, either by bending or focusing it, and can be used for a variety of applications including collimating light from a LED source. The specific type of lens you would need will depend on the characteristics of your LED and the distance you want to focus the light. Some factors to consider when selecting a lens for this purpose include the size and shape of the LED, the wavelength of the light, and the desired focal length. I would be happy to provide more information and help you find the right lens for your needs if you can provide additional details. Thank you.
 

What is an optic lens?

An optic lens is a transparent device made of glass or plastic that is used to manipulate light. It can focus, collimate, or disperse light depending on its shape and material.

What is the purpose of using an optic lens to collimate/focus light from a LED?

The purpose of using an optic lens to collimate or focus light from a LED is to control the direction and intensity of the light. This can improve the efficiency and effectiveness of the LED in various applications.

How does an optic lens collimate/focus light from a LED?

An optic lens collimates or focuses light from a LED by using its curved surfaces to refract the light. The shape and material of the lens determine the degree of refraction, allowing the light to be directed or concentrated in a specific direction.

What factors should be considered when choosing an optic lens for a LED?

When choosing an optic lens for a LED, factors such as the desired light output, viewing angle, and efficiency should be considered. The size and shape of the LED and the application it will be used in should also be taken into account.

Can an optic lens be used with any type of LED?

Yes, an optic lens can be used with any type of LED. However, the size and shape of the lens may need to be adjusted depending on the size and shape of the LED. Additionally, the lens may need to be made of a specific material to best suit the LED's light output and wavelength.
