The beam expander 1x-8x is part of the Silverline TM high-power lens series and is designed for laser applications in wavelength ranges of or – nanometers. The optical system of the objective lens is designed in such a way that a diffraction-limited image quality is achieved across the entire expansion range. We provide the laser beam expander holders (KLH-BE) for optical-axis adjustment of the laser beam expander. W Make sure that the beam expander is well aligned with the laser light axis. If the beam expander is inclining, the output light will also be inclined. It is not possible to obtain a decreased beam diameter by using the beam expander on the opposite side. Use it properly to obtain.

The age of computational imaging is merging the physical hardware-driven approach of photonics with advanced signal processing methods from software-driven computer engineering and applied mathematics. Compressive holography with a single-pixel detector. The divergence of the laser beam can be precisely adjusted to achieve tolerance compensation in the entire system, for example to compensate for thermal effects. With their optimized construction designthe beam expanders are extremely robust and compact so the lenses do not rotate during a set-up change. Skip to search form Skip to main content You are currently offline. In doing so, they enable different components of an optical system to adapt to one another. The beam expanders boast sturdy construction and compact housing.The beam expander 1x-8x is part of the Silverline TM high-power lens series and is designed for laser applications in wavelength ranges of or – nanometers. The optical system of the objective lens is designed in such a way that a diffraction-limited image quality is achieved across the entire expansion range. Using a 10X beam expander reduced the output beam diameter m away by over a factor of 5 when compared to the same laser without a beam expander. Application 3: Minimizing Focused Spot Size Spot size is typically defined as the radial distance from the center point of maximum irradiance to the point where the intensity drops to 1/e 2 of the initial value (Figure 6). PDF | Our work is equations are applied on an example of calculation of paraxial parameters of the three-element zoom system for the laser beam expander. Basic parameters of a Gaussian beam.

Schelkens}, year. 4x Reimaging Laser Beam Expander There are two reasons that you might want – or need – to expand your laser: • Reduce Intensity: If the laser beam is 4 times wider, its area is 16 times larger and its intensity (power or energy density) is 16 times lower. This can be a useful.

This can be a useful. Luckily, building a beam expander from off-the-shelf components is easily accomplished and can be fit into most budgets. The quality of the output is dependant only on the input beam and the component optics used. To create a beam expansion unit, it is important to know a few simple optical relationships, as well as what your input to output.Extracavity double-prism beam expander to correct the ellipticity of laser beams generated by semiconductor lasers (Maker and Ferguson, ). These expanders make use of the prism pairs first introduced by Brewster (). Generalized laser beam shaping devises as . The CSLM shown in Fig. uses a laser, pinhole, and beam expander to accomplish this goal. Lasers are common sources for CSOMs because they provide an inexpensive bright single-frequency light source.

A laser beam expander is designed to increase the diameter of a collimated input beam to a larger collimated output beam. EKSMA OPTICS offers compact Galilean type beam expanders for nm, nm and nm wavelengths. Compact beam expander has the possibility to be adjusted for the input beam divergence angle to obtain collimated, divergent or focused beam at the output. . purpose beam expander.

Optics: How to Build a Beam Expander Beam expansion or reduction is a common application requirement in most labs using lasers or light sources and optics. There are many ready made beam expanders available on the market, but often they are not available in the required expansion ratio or spectral range. And, for students, or those working within a tight budget, the plug and play solution . Gaussian beam depend not only on the specifications of the beam expander, but also on the laser beam parameters as well as the positions of the optical lenses. The function of a beam expander is to reduce the divergence angle of laser beams and thus make the focused beam diameter smaller.
