PFG - Optical Prisms
If you are in search of an optical prism within the United States, you have come to the right place. PFG Optics is a leading optical prism manufacturer and supplier of a vast array of optics for a variety of industries. Our company specializes in the production of a comprehensive selection of high-precision prisms, with specifications including flatness, angle, dimension, transmitted wavefront, clear aperture, surface quality, and sharp roof. Our product offerings include a diverse range of prisms such as right angle prisms, pentaprisms, boresight prisms, delta prisms, Porro prisms, corner cubes, dispersing prisms, rhomboids, as well as dove prisms. Additionally, we possess a wealth of experience in producing Risley prism pairs, commonly used in aerospace applications for beam steering, which can be fabricated in various sizes and degrees of wedge.
Our team of advanced optical components experts possess the industry knowledge and expertise in prism manufacturing processes, technology, fabrication techniques, manufacturing equipment, and metrology to deliver superior performing prism optics. We often use substrates such as most optical glasses, fused silica, ZnSe, Si, ZnS, MgF2, CaF2, and Cleartran in our manufacturing process.

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 dedicate 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.
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, microcopy 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.
