Geometric optics lab

This lab consists of many short optics experiments. This short intro will show off the main steps to the geometric optics lab. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.

These range from simple things like eyeglasses to complex instruments, such as the Hubble Space Telescope.

A useful reference for this and subsequent experiments is. A copy is available in the lab. The basic physics is contained in two laws: For reflecting surfaces (Fig. ), the . Purpose: Students will learn about refraction, lenses, and mirrors. Introduction: Few things are as basic as vision. These optical instruments work by changing the direction of light rays using optical elements like lenses (refraction) and mirrors (reflection).

Some compound instruments combine both types of optical elements. LABORATORY I: GEOMETRIC OPTICS. In this lab , you will solve several problems related to the formation of optical images. The video shows of the setup and the general procedure for each part of . Significant changes have been made since then, and the manual used during the current academic year is in NOT available yet on the WEB. Hardcopies can be purchased at the bookstore.

Geo” course back at school really prepared him well for his laboratory work here. This month Manuel is learning how to “grind and polish optical surfaces to spec,” and how to apply the principles of geometrical optics to determine when the surfaces are “near tolerance. The lenses in this experiment can be considered thin. There are two types of lenses used in this lab : convex (vexed or bowed outward) and concave (caved or bowed inward). Lenses in this write-up are pictorially represented by their cross-sections.

You are provided with: laser (with diffuser), ray table, smoke lens set, optical bench, converging lenses, variable aperture, white light source. Geometric Optics Lab Exercises. In addition, there are several ray boxes and mirrors to be shared among lab groups.
