Focusing and Collimating - Newport

This image is at the focal point of the lens, s 2 = −f 1, because a well-collimated laser yields s 1 ~ ∞, so from the Gaussian lens equation s 2 = f. Adding a second lens with a positive focal length f 2 and separating the two lenses by the sum of the two focal lengths −f 1 +f 2 , results in a beam with a radius y 3 = θ 2 f 2 and divergence angle θ 3 = y 2 /f 2 .

Focusing and Collimating - lcoptical.com

Focusing and Collimating. Application 1: Focusing a Collimated Laser Beam. As a first example, we look at a common application, the focusing of a laser beam to a small spot. The situation is shown in Figure 5. Here we have a laser beam, with radius y1 and divergence θ1 that is focused by a lens of focal length f.

Focusing & collimation – RXOPTICS GmbH & Co. KG

Focusing Fig. 1. Focusing. Focusing of the x-ray beam is one of the major applications of refractive x-ray lenses from RXOPTICS. Focusing maps the primary x-ray source to a focal spot, the so-called secondary source (Figure 1).. This is done, for instance, to adjust the beam to the sample size and to increase the photon flux on the sample in x-ray diffraction, absorption, and fluorescence ...

Laser Beam Collimation - integratedoptics.com

Usually, the first idea for collimating and circularizing a beam emitted by a semiconductor laser is to use two orthogonally positioned cylindrical lenses. As shown in Fig 3. One lens is placed to collimate the beam in the fast axis direction, another – in slow axis direction. The ratio of focal lengths of both lenses is related to the ratio of laser beam divergence in fast and slow axes ...
