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

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.

Micro Spherical Lenses
Under the condition of high refractive index, some optical components can achieve short focal length. Therefore, the micro lens becomes an ideal choice in the field of high precision applications.
Through years of accumulated processing know-how technologies and production capacity, high standard thin film coating performance and strict testing requirements, Photonchina provides customers with one of the world's smallest but excellent micro lenses products, which have been widely used in various medical devices (endoscope lens, for example), precision surveying and optical communications instruments.
From design, manufacturing to optical coating, from endoscope lens, capsule lens to special-required rod lens, from single mini lens to glued lenses system, engineers in Photonchina implement strict production process to ensure stable quality, competitive price as well as responsive lead time.
A variety of optical glass or other materials, such as BK7, N-SF11, H-LAF76, Fused Silica and so on are available for customers design. H-LaF53, for instance, has often been used in endoscope lens or capsule lens production. We have a wide range of lenses in shape: convex, concave, biconvex, meniscus etc.

Photonchina produces the smallest rod lenses for customers at home and abroad.
Micro rod lenses: 0.5-1.8mm diameter, 1.0-25mm length, with one end of designated curvature radius and another end of arbitrary angle.
Both ends of arbitrary radii or angle are also available. Highly customized products for a wide range of applications from medical device, fiber communications, optical display and surveying equipment.
What is more, we can provide unique rod-shaped glued lenses by combining special gluing/cementing technics and edging skill. These glued/cemented rod lenses subassembly can be made of up to four single micro rod lenses with various combination. Rod lens assembly systems are able to provide images with greater brightness, contrast and color reproduction than conventional lenses.
Rigid endoscope, for instance, which usually has a series of high-resolution optical glass rod lenses, can be forward viewing (0 degrees) or angled (10120 degrees) to allow visualization out of the axis of the telescope and increase the FOV by rotating the instrument. The optical quality of lens-generated images of rigid endoscopes still surpasses that of the fiber-optic or digital images produced by flexible scopes.
High performance optical coatings for rod lenses are provided.
Optical glass material NBK7, N-SF11 from Schott, Corning 7980 etc, are all available.
