Plano Optics
Building on our strengths in optical cylinders and optical fabrication, Torrent Photonics is able to deliver high precision optical flats, windows, and filters, to meet the complex needs of medical and defense.
Precision Optical Flats
Custom plano optics or optical flats are available as one-sided optics for reference surfaces, or double-sided optical flats for use as optical windows and test plates due to their capacity for light transmission. We carry a variety of materials suited to the full range of wavelengths, from visible to NIR to IR.
Torrent Photonics has the tools and know-how to produce plano optics in both volume and size on a large scale. Our 72” planetaries allow for up to 30” parts and are better than 1/20th wave at 632.8nm. Our Speedfam double lap polishers produce parts with less than 5” parallelism. Torrent can deliver thousands of optics over 8” per month. Scratch dig or 10/5 on visible optics and 20/10 on IR optics are possible.
Customization Optics Designed for Performance
Depending on the needs of your application, Torrent Photonics has decades of experience making Plano optics from various materials. As a result, we can produce plano optics and doublets that fit your requirements, whether they require hard ceramics or soft optical materials.
Torrent has extensive experience and one of the largest capacity collection of double-sided grinding and polishing machines in North America, fabricating and producing customized IR, UV, and visible windows in various sizes, shapes, and substrates servicing the medical, defense, industrial, and scientific fields. With remarkable parallelism and transmitted wavefront produced by the double-sided production process, we can deliver visible windows for industrial and biomedical applications and IR windows for infrared and military/defense applications.

Visible Windows
Visible windows are excellent for safeguarding image or display systems, including optical systems and other optical components. Torrent Photonics can custom-build visible windows in several sizes, shapes, and substrates with an option for AR coating on one or both surfaces for various optics applications with a wide range of temperatures or other complex environmental factors.
Infrared (IR) Windows
Infrared windows are commonly used in the infrared light spectrum for FLIR, FTIR spectroscopy, medical systems, thermal imaging, or other optical applications. In addition, IR windows can aid in securing your personnel and machinery. Torrent Photonics can custom-create IR windows in various sizes, shapes, substrates, and coatings with an option for AR coating on either or both surfaces.
UV Windows
In medicine, industry, and military fields, ultraviolet windows are frequently utilized in conjunction with laser equipment or other applications. To best meet your unique requirements and applications, Torrent Photonics can assist in identifying the optimum substrates, UV coatings, and other optical qualities and produce UV windows specifically for you with an optional AR coating on one or both surfaces.
Torrent offers several optical flats, reference flats, test flats, or test plates, to meet precision tolerances for the most demanding and rigorous applications. Precision optical polishing yields an incredibly flat optic which can be used as a reference for evaluating the flatness of other optics using a monochromatic light source or in interferometry applications.
Optical flats are made to order in custom sizes with various coating and beveling options. They can even be polished to contain a small wedge to lessen back reflection. Torrent will satisfy your requirements for precision and accuracy whether you need single-sided or double-sided Plano optics that are λ/4, λ/10, or λ/20 in size.

Single Surface Optical Flats
Flats with only one side of precise polishing are called single-sided optical flats. The opposing side is not polished to specifications but is left clear. Other optical materials, such as wedges or optical mirrors, can have their flatness tested using the polished side of the optical flat. It can also function as a substrate for optical windows.
Double Surface Optical Flats
Plano optics with a known flatness on both sides are called double-sided Plano flats. A double-sided optical flat can be used as a substrate for a window or to evaluate the flatness of an unknown surface on either side.
