Precision-manufactured device greatly extends the use and range of your optical collimator for rifles equipped with large objective scopes or scopes mounted in rings high above the centerline of the bore. Very easy to use: Mount your collimator onto the elevation arm insert your bore spud in the elevator block then lock with thumbscrew. Insert your spud into the bore and move elevation shaft up or down. Adjust the collimator so its grid view is near the center of the objective lens and lock collimator height with second thumbscrew. Mfg: W. Frear Innovations SPECS: Elevator Block - Aluminum. 1¾" (4.5cm) long ¾"(1.9cm) wide 1¾" high. Elevation Shaft - Stainless steel. ¼" (6.3mm) diameter. Elevation Arm - Aluminum. 3⁄8" (9.5mm) diameter. Includes instructions.
Gets the boresighter up high enough to align the scope on guns with see-through rings or integral mounts (like the AR-15) that sit high above the bore. Three parallel "V"s give a range from 1" to 2-3/8" between the bore spud and the collimator spud. Tilt for offset mounts. Accepts Sweeny Site- A-Line Redfield or Tasco spuds. Mfg: Alley Supply/Sweeny Sitealine SPECS: Aluminum body brass and steel screws. 3-13/16" (9.7cm) long 1" (2.5cm) wide 7/8" (22.2mm) thick. Weighs 4 oz. "V" spacings of 1" 1-3/8" (3.5cm) and 2-3/8" (6cm). Does not accept Bushnell spuds.
The Interstellar Boundary Explorer (IBEX) mission will provide full sky images of Energetic Neutral Atoms (ENAs) from interstellar space. The Collimator is tasked to restrict the Field of View (FOV) of IBEX, as well as repel ions up to 10keV in energy to a degree greater than 104, and electrons up to 600eVto the same degree. This thesis retests the capability of the Collimator to perform these functions, as well as improving upon the testing procedures.

- By projecting a laser beam form the center of the barrel axis of your firearm, this laser bore sight collimator allows you to instantly and accurately set your sight or scope - It conveniently works with all 0.22-0.5 caliber rifles and pistols even after a long trip -
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

Reflections in a spherical convex mirror. The photographer is seen reflected at top right A curved mirror is a mirror with a curved reflective surface, which may be either convex (bulging outward) or concave (bulging inward). Most curved mirrors have surfaces that are shaped like part of a sphere,[citation needed] but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems suffer from spherical aberration.
Convex mirror
A convex mirror diagram showing the focus, focal Length, centre of curvature, principal axis, etc A convex mirror, fish eye mirror or diverging mirror, is a curved mirror in which the reflective surface bulges toward the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. Such mirrors always form a virtual image, since the focus F and the centre of curvature 2F are both imaginary points "inside" the mirror, which cannot be reached. Therefore images formed by these mirror cannot be taken on screen. (As they are inside the mirror) A collimated (parallel) beam of light diverges (spreads out) after reflection from a convex mirror, since the normal to the surface differs with each spot on the mirror. Image
Convex mirror image formation The image is always virtual (rays haven't actually passed though the image), diminished (smaller), and upright . These features make convex mirrors very useful: everything appears smaller in the mirror, so they cover a wider field of view than a normal plane mirror does as the image is "compressed". Uses
Convex mirror lets motorists see around a corner. The passenger-side mirror on a car is typically a convex mirror. In some countries, these are labelled with the safety warning "Objects in mirror are closer than they appear", to warn the driver of the convex mirror's distorting effects on distance perception. Convex mirrors are used in some automated teller machines as a simple and handy security feature, allowing the users to see what is happening behind them. Similar devices are sold to be attached to ordinary computer monitors. Camera phones use convex mirrors to allow the user correctly aim the camera while taking a self-portrait. Properties of convex mirror can be found in objects not specifically designed for this purpose, such as some thumb tacks, Christmas baubles and even sunglasses. Concave mirrors
A concave mirror diagram showing the focus, focal Length, centre of curviture, principal axis, etc. A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point, therefore they are used to focus light. Unlike convex mirrors, concave mirrors show different types of image depending on the distance between the object and the mirror itself. These mirrors are called "converging" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles, since the normal to the surface differs with each spot on the mirror. Image Effect on image of object's position relative to mirror focal point Object's position (S),focal point (F) Image Diagram S < F(Object between focal point and mirror) Virtual Upright Magnified (larger) S = F(Object at focal point) the image is formed at infinity. (Note that the reflected light rays are parallel and do not meet the others. In this way, no image is formed or more properly the image is formed at infinity.) F < S < 2F(Object at 2x focal point) Real Inverted (vertically) Magnified (larger) S = 2F Real Inverted (vertically) Same size S > 2F Real Inverted (vertically) Diminished (smaller) Mirror shape Most curved mirrors have a spherical profile. These are the simplest to make, and it is the best shape for general-purpose use. Spherical mirrors, however, suffer from spherical aberration. Parallel rays reflected from such mirrors do not focus to a single point. For parallel rays, such as those coming from a very distant object, a parabolic reflector can do a better job. Such a mirror can focus incoming parallel rays to a much smaller spot than a spherical mirror can.
