1. "Then we thought of collimating beams , and we were off . " e. 2. Other elements, such as prisms and diffraction gratings often need large quasi-collimated beams . 3. Almost all measurement and testing techniques require collimated beams . 4. Collimated beam pattern and D / S curve for all 16 spot frequencies has been taken.5. This corresponds to a pair of lenses that transform a parallel ( collimated ) beam into another collimated beam . 6. Although the system does not alter the divergence of a collimated beam , it does alter the width of the beam. 7. At a point within a collimated beam , the spectral flux density vector has a value equal to the Poynting vector, 8. Much early experimental work on Rydberg atoms relied on the use of collimated beams of fast electrons incident on ground-state atoms. 9. Lasers are advantageous due to their monochromatic wavelength, their collimated beams ( less than 0.05?angular divergence ), and their intensity. 10. :Wouldn't the collimated beam get diffracted and then get focused later ? talk ) 20 : 52, 17 January 2012 ( UTC)
