Optical Illusion: Your Complete Guide to Custom Optics

Optics is the science of light, and you use it more than you think. Optical technology is everywhere, from your smartphone to your digital camera to telescopes and more.

Industrial, military, defense, medical, and similar fields often rely on custom optics to fulfill a specific purpose. These days, opticians and engineers can create new components to suit almost any application.

See why there is a need for custom-made lenses and made-to-order components, and learn about the different types of optics in this guide.

What Are Custom Optics?

When it comes to manufacturing optical lenses, there are two choices: stock lenses and custom lenses. Although stock lenses suit many applications, there are times when there is a need for a customized product. High-precision applications often require a specialized lens or component, which is where custom optics come in.

When you work with an optics company like pfgoptics.com, technicians and engineers will be able to create the perfect lens for industries such as defense, medical, and more.

Types of Custom Optics

There are many different types of custom optics. Here are a few types of lenses and components and their various uses.

Precision Lenses

When you need to meet required specifications, precision lenses are often the best way to go. Lenses can be made of glass, fused silica, and crystalline.


Prisms are a type of custom optics made to meet specifications for flatness, angle, dimension, surface quality, and so on. Various industries rely on prisms, such as the defense and aerospace industries.


Optical flats include windows, mirrors, and wedges. There are also many coatings available for optical flats, such as ultraviolet and mid-wave infrared.

Cylindrical Lenses

A cylindrical lens stretches light into a line. At least one and sometimes both sides of the lens have a concave or convex shape.

Thermal Imaging

Thermal imaging optics are often used in aircraft, military vehicles, naval ships, and so on. These optics can also be coated to help preserve them and ensure performance in any environment.


Diffusers are usually used for lighting applications. These custom optics will diffuse and scatter light. They are often made from glass or acrylic.


Beamsplitters are optical devices that split a beam of light into two. They can be applied to various types of prisms. There are plate and cube beamsplitters, and they come in various sizes and glass types.

Dust Covers

Windows or dust covers protect a lens or other sensitive component from dust, debris, and damaging elements. Many industries have these parts custom-made in various sizes or configurations.

The Future of Custom Optics

Optical technology exists everywhere these days, from lasers and sensors to microscopes and more. Various industries rely on custom optics every day. Plus, the future of custom optics looks bright as we continue to explore new materials and meet increased demands.
