Laser Collimation

Need help calculating the diameter of a laser beam projected onto the moon?
The collimation of a laser beam is limited by diffraction; that is, the angular beam spread Δθ is at least as large as Δθ λ/D, where D is the diameter of the laser's aperture. What is the diameter of the beam spot projected on the Moon, 3.8*10^8 m from a laser of aperture diameter 16 mm emitting light of wavelength 510 nm?
The spread of the beam at distance L will be L*tanθ. Because the angle is small, tanθ ~ θ so the spread is L*λ/D = 12 km

Orion LaserMate Pro Laser Collimation Kit $99.99 If you'd like a collimator that stands up to the rigors of real-life field astronomy, our new LaserMate Pro Heavy Duty collimation kit is for you. Even if you dropped it into your bag, don't worry. Did you accidentally bang it? No problem. This hardened design will guarantee the alignment of the collimating laser for a lifetime. Collimation is the process of the mechanical centering of your optics to give your telescope the best possible optical performance. If you own a Newtonian reflector (especially an assemble-on-site telescope) it needs to be checked every time you reassemble it. For tack-sharp images through some telescopes, you may even need to check alignment during your nighttime viewing session as well. With the LaserMate Pro, you'll get a lifetime of precise collimation so you'll enjoy the best possible visual and imaging experience to get the most out of your telescope. Achieve quick collimation with laser precision in a simple two-step process. First, insert the LaserMate Pro into a standard 1.25" eyepiece holder and adjust the secondary to center the red laser dot on the primary mirror. For 2" eyepiece holders, use a 1.25" to 2" expansion adaptor or Orion's Precision Centering Adapter for greatest accuracy. Then, use the included Cheshire eyepiece for final collimation by tilting the reflector's primary mirror. Illustrated instructions and centering dots are included. The LaserMate Pro is built of durable metal in gunmetal grey and has a lifetime guarantee! |

The Susi Beam Emittance Collimation Channel. $115.71 The Superconducting Source for Ions (SuSI) is a newly designed, fully superconducting Electron Cyclotron Resonance (ECR) ion source working at 14.5 and 18 GHz microwave frequencies at the National Superconducting Cyclotron Laboratory (NSCL). Preliminary results indicate that SuSI is capable of producing ion beam currents comparable to other 18 GHz sources 1]. In parallel to the increase in beam currents offered by SuSI compared to existing sources at the NSCL, a dedicated collimation channel has been designed to tailor the beam emittances to the K500 cyclotron acceptance, which is about 75 pimmamrad ?], so as tcy minimize the beam losses in the cyclotron extraction channel. The collimation channel uses four collimation stages and three solenoids in between to rotate the beam transversely in phase space. Beam simulations showed that the proposed design can efficiently collimate Learns from SuSI under various scenarios. The collimation channel was commissioned with SuSI in a test area in June 2009. Experimental results have confirmed the effective collimation capability observed in the beam simulations. The collimation channel anti SuSI were moved to the Coupled Cyclotron Facility (CCF) ECR. area in July 2009 in replacement of the former 6 GHz SuperConducting ECR ion source (SCECR). Since then the collimation channel has been recommissioned and provided adequate capability for emittance collimation and ECR parameter optimization at the CCF.

Orion LaserMate Deluxe Telescope Laser Collimator $69.99 With our LaserMate Deluxe you will get perfect alignment of your reflector's optics, and faster than with standard collimators. Precise collimation ensures that you'll enjoy the sharpest possible images. Using the LaserMate Deluxe is a simple one-step procedure. A new rear view port in the anodized aluminum housing lets you see both the emitted and return laser beam spots while standing at the rear of the telescope. Just tweak the scope's collimation screws until the beams overlap in the center of the LaserMate's target pattern. Done! Perfect collimation at lightening speed. Only 4" long, it's easy to stash in your accessory case. Ideal for Newtonians and a must for those with focal ratios of f/5 or lower. Fits any 1.25" eyepiece holder. Includes one CR2032 battery and instructions. One-year limited warranty. This Class IIIA laser product complies with US 21 CFR 1040.10 and 1040.11 |

Laser Projection by Busker, Matthias [Paperback] $114.71 Lasers are an interesting option as a light source for projection displays, because of their high directivity. As a result, a high brightness light source with a small beam profile, a good beam quality and good collimation characteristics is obtained. This allows the application of small light engines and display panels without loosing much intensity. As a result, a small and quite cheap projector can be gained. If the panel costs are still too high, laser sources can also be used to realize even cheaper architectures that use 1D display modules or a flying spot scanner. Additionally, the laser beam is highly monochromatic, so a projection unit using three primaries can cover a large colour gamut. The intention of this book is to give an overview on state of the art projection techniques, applicable laser sources and challenges in setting up micro or even high power laser front projection systems.
