Prism Products Selection

Right Angle Prisms

Right Angle Prism

Precision glass contact for many to use these to deviate the direction of light. With precision right angle prisms it’s possible to use this in a Porro setup when light is incident through the hypotenuse for deflection of 180 degrees.

Corner Cubes

Corner Cube Prism

These act as reflectors, a type of retroreflectors. These optics also can provide great parallelism of incoming and reflecting beams.

Rhomboid Prisms

Rhomboid Prism

These are used to displace a laser beam without changing its direction.

Dove Prisms

Dove Prisms

Compare this product to right-angle prisms, rhomboid prisms missing their top part. We use these to invert images.

Penta Prisms


This is a 5-sided reflection optic also with 4 reflecting surfaces. This has the ability to reflect light at 90 degrees independent of the angle of incidence.

Boresight Prisms
Delta Prisms


This optical element provides a compact folded form of the Dove.

Porro Prisms

Porro Prism

We these you can edit the image orientation. So the degree of a porro optical system will depend on how many axes the specific image needs to be altered in.

Pechan Prisms

Pechan Prism

We normally use these to rotate an image by 180°. They are also commonly used in binoculars.

Risley Prisms

Risley Prism

This is actually two wedge prisms located close to each other but can be rotated independently.

Anti-reflective Prisms

Anti-reflection coated prisms and right angle prisms are compared to enable high light throughput for maximum contrast and also uniform images.

Our optics coatings provide top surface quality and blackening. while these are widely utilized in projection displays, they also have multiple uses for different types of optics: physics, medicine, science, telescopes, microscopes, optical instruments, laser diodes, lithography, and more. For telecommunications and spectroscopy, we often use equilateral prisms. Our typical coatings include an anti-reflective coating, high-reflector (HR), dichroic, and also polarizing designs. We also offer optical coatings, metrology, laboratory optical component fabrication, and other prism manufacturing capabilities.

Beamsplitter Optical Prism

Our precision optical manufacturing group always supplies our reflective prisms for imaging systems. Due to the total internal reflection (TIR), lighting entering the optic can go through multiple reflections until it reaches an output phase. We use custom optical prisms for applications including different types of prisms geometry, cube prism optics, physics, medical, defense, and also research industries contact.

Beamsplitter Optical Prism

Bk7, custom prism grout colors, caf2 prism, micro prim optics, prism optical glasses, and anamorphic prisms are all a part of our optics supply. Dispersive prisms are normally in the shape of a triangular prism and are used to differentiate the wavelengths of an incident beam of light into a variety of glass contact precision prism zygo optical paths. We are one of the leading optics products manufacturing companies in the United States.

all types of prism optics

So you can choose from cube beamsplitters roof prisms compared to projector engines dichroic prisms x cube, prism bk7 contact retroreflective optical, and more. We also work with material bk7 fused silica laser, surface quality scratch dig wavefront compared to Guoguang optical glass dimension tolerance, and so on. Moreover, our fiber optical components manufacturer provides your desired results. Also, the manufacturer of precision optical instruments laboratory has all lean manufacturing certifications and includes a lean manufacturing tool. From prism bk7 fused silica contact, scratch dig paddle, and grade optical glass dimension tolerance, to tools of lean manufacturing, we can help you with any of your needs!

Our custom prism grout color chart can help you find your optimal large optical prisms for sale. Our products include laser beam splitters, glass prisms, corner cube prisms, fresnel prisms and rhombs, and other optical systems. A wedge prism has a shallow angle and can be used for beam steering in a Risley prism pair. So each wavelength will be reflected at different angles thus moving the refractive index for every wavelength contact precision prism polarizing glass.

High-precision custom optics manufacturer


The manufacturing of prisms is a captivating process, owing to the intricate science that underpins the functionality of these optics. At PFG Optics, we frequently produce reflective prisms for utilization in imaging systems, catering to both commercial and military applications. In certain instances, we apply specialized coatings to these prisms, transforming them into beam splitters. The utilization of a prism can often lead to a reduction in the size and weight of an optical system and can prove to be easier to align, as it substitutes a series of mirrors or elements for a single prism. Furthermore, we have also fabricated and assembled a wide array of prism opto-mechanical assemblies, which are custom-made to suit the specific requirements of our clients. The coating of prisms in large quantities can be challenging, owing to the stringent surface specifications and variations in size and shape. For example, when producing prisms for laser applications, we maintain a surface quality of 10-5 scratch-dig. Thus, for highly precise prisms produced in low quantities, automated processes are less applicable as they require meticulous attention to detail. Experienced opticians are required to personally inspect prism surfaces during the prism manufacturing process and throughout the polishing and shaping processes, in order to verify and adjust as necessary. This could be during the contacting, blocking, or shaping processes. Our team of engineers dedicates a substantial amount of hands-on time to your tight-tolerance prisms, and our inspection team handles and checks each optic with the utmost care. This level of involvement is one of the reasons why our quality surpasses that of our competitors in the precision prism manufacturing market.

uses of optical prisms

Optical prisms can be used for a variety of purposes, depending on the specific properties of the prism and how it is designed. Some of the most common uses of prisms include:
  • Dispersion: Prisms can be used to separate white light into its individual colors, a process known as dispersion. This is the principle behind the rainbow colors that can be seen when light is refracted through a prism.
  • Reflecting and Redirecting Light: Prisms can be used to reflect and redirect light, making them useful in optical systems such as telescopes, cameras, and binoculars.
  • Measuring Angles: Prisms can be used to measure angles by reflecting a laser beam onto a scale or detector.
  • Beam Steering: Prisms can be used to steer laser beams in aerospace, medical, and industrial applications.
  • Polarization: Prisms can be used to separate light into its polarization states, which is useful in applications such as LCD displays, 3D glasses, and polarimetry.
  • Imaging: Prisms can be used to create images, such as in periscopes, microscopy, and endoscopy.
  • Opto-Mechanical Assemblies: Prisms can be used in combination with other optical components and mechanical parts to create opto-mechanical assemblies for various applications.
  • Interferometry: Prisms are used to split a laser beam into two or more beams that can be recombined later in order to analyze the interference patterns that result.Overall, the versatility of prisms makes them applicable in a wide range of fields including scientific research, telecommunications, medicine, and military technology.
