PPT-Fresnel Prisms & Risley

Prisms What is a fresnel prism A prisms angle of refraction depends only upon the angle of the surfaces and the index of refraction of the material of which the prism is made The angle of refraction is independent of the prisms thickness. You will be determining which can hold mo re popcorn To do this you will have to find a pattern for the dimensions for containers Materials 85 inch by 11 inch white paper 85 inch by 11 inch colored paper Tape Popcorn Plate Cup Ruler Take the white p Diffraction optical elements: reconstruct semi-arbitrary 2D or 3D optical fields. Numerical design: flexible encoding strategy high diffraction efficiency . and uniformity . OPTICAL DEVICE. that is used for being able to see around and over objects. . Periscopes are generally made two different ways.. With mirrors. With prisms. To the right are diagrams of the two most commonly used periscopes.. Positive Focal Length Fresnel Lens Used as a Collimator Negative Focal Length Fresnel Lens Used as a Diverger HIGH QUALITY FRESNEL LENSES IN A VARIETY OF SIZES & FOCAL LENGTHS The Fresnel LensCenturie 6.4.5 I can find the volume in rectangular and triangular prisms.

Diffraction of light when two fingers brought close together . infront of a light source . Diffraction by razor blade when illuminated by intense blue light . “light is never known to follow . crooked passages nor to . Vocabulary. Surface Area: . the sum of the areas of all the faces of a 3D figure. Measured in square units (ex: ft. 2. , in. 2. , m. 2. , . etc. ). Faces: . sides of a figure. Prism: . 3D shape with two congruent (equal) bases and parallelogram sides. light bends or refracts when it moves from one medium to another. the light bends because it changes speed. if light slows down it bends toward the normal. if light speeds up it bends away from the normal.
