Wedge prism has plane inclined surfaces. It deflects light toward its thicker portion. It can be used individually to deflect a beam to a special angle. Two wedge prisms work together can assembly an anamorphic prism to correct the elliptical shape of laser beam. The wedge prism is ideal for laser beam steering applications. By combining two wedge prisms which can be rotate individually, we can direct the input beam to anywhere within the cone angle �¸d, where �¸d is 4x the specified angular deviation of one wedge

PARAMETER:
The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from the prism.

Dimension Tolerance:
The wedge prism can be used to individually deflect a laser beam by a certain angle or combined with another optical wedge prism for beam deviation purposes. A single prism can shift the incident beam by a specific angle. When two wedge prisms are used together, they can function as deformable prisms to correct the elliptical beam output of a laser tube or to deflect the beam at various angles within a 4�¸ range, where �¸ represents the deflection angle of a single prism. This beam shaping is achieved by independently rotating the two wedge prisms, making it ideal for beam scanning at different positions in imaging applications.
Features of Wedge Prism
The characteristics of wedge prisms include their very small apex angle (typically less than 1/10 radian), which results in minimal deflection of light as it passes through, regardless of the angle of incidence. In optical instruments, two wedge prisms are often combined and rotated relative to each other to produce different deflection angles or to convert the minimum deflection angle of light into the relative rotation angle of the two prisms. This setup is used to compensate for small angular deviations in the measurement of light. Such prisms find applications in many optical instruments, including military rangefinders and camera viewfinders.
Applications of Wedge Prisms
Laser Scanning: Wedge prisms can adjust the direction of the outgoing beam through rotation, making them commonly used in laser scanning devices.
Optical Pointing: In machine vision applications, wedge prisms are used to position the cameraâ??s field of view to the region of interest.
Beam Attenuation: By utilizing double Fresnel reflections, wedge prisms can attenuate high-power lasers while maintaining the beamâ??s polarization, size, and shape.
Beam Shaping and Translation: Wedge prisms can be used for beam shaping and translation, making them suitable for a variety of optical systems and applications.

HR manufactures a wide variety of Prisms. Custom designs including right-angle, equilateral (dispersing), and cube Prisms, dove Prisms, roof Prisms, penta Prisms, and retroreflectors. These Prisms are available in a wide variety of materials, including glass, Germanium, Silicon, ZnSe , ZnS , Fused Silica, Quartz and calcium fluoride. Dimension 2mm to 500mm.
Corner Cube Prism is also called Retroreflector or Trihedral Prism. In the Corner Cube Prism, three reflecting surfaces are perpendicular to each other, like the side wall of the cube. The input surface is perpendicular to the cube diagonal. Disregarding the angle of incidence, the output beam is parallel to the input one, but it is of opposite direction. Inset of the several corner prisms, for better matching, their entrance-exit surface is often hexagonal. In case of this prism the phenomenon of full internal reflection occurs so it is not necessary, (however it is possible) to put mirror coating on the reflecting faces. Normally the reflection surfaces are Al reflection coating, and then covered with Cu and Black Painting.
Note for corner cube retroreflector:
(1). Besides N-BK7, custom-made corner cube Prisms made of other optical materials are available.
(2). Corner Cube Prisms with lower deviation tolerance, such as 1, 30, or 10, are available.
(3). Corner Cube Prisms with better surface Quality (better than 40/20 or 20/10) are available.
(4). HR or Metal reflection coating(Al, Ag, Cu, etc.) on reflection surfaces is available.
(5). AR coating on input/output surface is available upon request.
(6).Custom-made non-standard Corner Cube Prisms at any other size are available upon request.

Roof Prism
A roof prism is a reflective optical prism to make two cross beams be parallel with each other. It contains a section where two faces meet at a 90 angle. These two 90 faces resemble the roof of a building, giving this prism type its name. Reflection from the two 90�° faces returns an image that is flipped laterally across the axis where the faces meet.
In some cases, passing through the prism, the image is both deflected right-to-left and top-to-bottom. The hypotenuse of the prism utilizes total internal reflection (TIR) to reflect the image through the prism. Polarization states may become rotated during reflection.
As a rich experienced manufacturer, substrate material in Photonchina can be chosen from all optical glasses (N-BK7, for instance), Fused Silica, Si, ZnSe, ZnS, CaF2, MgF2 etc.
Photonchina has been focusing on dove prism manufacture for more than decades in order to meet demands of customers worldwide in applications ranging from image displaying to fiber communications.
Dove prism is a type of reflective prism which is used to invert an image. These prisms are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image's handedness is changed to the opposite sense.
If you look through the prism and rotate it around a longitudinal axis, the image rotates through twice the angle through which the dove prism itself rotates. For optimal performance, you may use dove prisms with collimated light. The top surface of each dove prism is ground and the longest length features an unbeveled sharp edge.
Dove Prisms are offered uncoated, with anti-reflection coated diagonal faces, or with aluminized diagonal faces. Aluminized dove prisms feature a protected aluminum coating with black Krylon paint on the diagonal faces and are ideal for displaced retroreflection. They provide a u-turn for incident laser beam light.

Penta Prisms
Penta prism can deviate an incident beam without inverting or reversing to 90.The deviation angle of 90 is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling. The reflecting surfaces of this Prism must be coated with a metallic or dielectric coating. The standard Penta Prism reflecting surfaces are coated with aluminum or enhanced aluminum.
Note:

(2). Penta Prism at bigger size is available.

(5). Besides uncoating, Anti-Reflective(AR) coating is available upon request.

Sheet cane is a hand-woven product which is used as seating on some antique and most modern chairs. This type of seating is usually fitted into a continuous narrow groove cut into the top surface of the seat frame and held in place with a cane beading and glue. It is available in the common open weave and in a close weave often originally used on antique American chairs. We offer two widths in the open weave, 18 inch (457mm), and 24 inch (610mm), and 18 inch (457mm) in the close weave. When ordering sheet cane for chair seats you need to provide the dimensions of the seat and an accurate measurement of the width of the groove (in metric to the nearest 0.5mm), so that we can supply the appropriate beading size. Sheet caning instructions and timber wedges used for fitting sheet cane are also available.
