Optical Alignment Lab
Part 1
The goal is to align a laser through two irises. This is done using the law of reflection, a laser was bolted down and pointed at mirror 1 which is positioned at 45°, this beam will be reflected off at an angle of 45°, creating a 90°. Then mirror 2 is then placed in a position for the beam to hit it at a 45°, creating another 90° angle so that it can pass through irises 1 and 2.
Part 2
The goal is to increase the beam width and collimate the beam using a telescope. This is completed by adding lenses. Lens 1 and 2 had focal lengths of 30 mm and were 60 mm apart.
Part 3a
The goal is to build an optical system based on a diagram, we chose a beam expander. This was completed by using diverging lens with a focal length of -30 mm and a converging lens with a focal length of 30 mm.
Part 3b
The goal is to build an optical system based on a diagram, we chose the microscope. This was completed by using different lenses with focal lengths of -75 mm, 250 mm, and 150 mm.
