Homework Statement: Lens questions.
Homework Equations: idk

Hello, so I was wanting to use a laser beam and purchase a few lens' online for a project and wanted to get something similar to the image below, where i would end with a horizontal light ray i was wondering if anyone knows the equations that would be required to figure out the distance from each of the lens to the focal point and the angle at which the bend at from lens to lens to the focal point. I suppose I would also have to account for the refraction within the lens also, so is their anything i can use to account for that as well.
THANK YOU SO MUCH

Hi,

end with a horizontal light ray

Seems to me you start out with a horizontal (?) light ray and end up with a diverging beam after the focal point...

Homework Equations: idk

Let me revert that: what do you know ? about lenses and imaging ?

Thin-lens equations should suffice to get you started, assuming you don't need millimeter-scale precision or better. Try this site and see if it helps: https://courses.lumenlearning.com/boundless-physics/chapter/lenses/

Note that you may actually need to measure the focal lengths of your lenses. Even if they are given, it never hurts to check.

I suppose I would also have to account for the refraction within the lens also

Not true. Lenses like these always have a single refractive index that does not vary as the light travels through the material. All you need to account for is the change in the refractive index at each surface.
