Polymer Optics is a leading supplier of Passive Infra-Red (PIR) lenses and PIR lens design services to the security and lighting control industries.
While our lenses are mostly used for security and lighting applications, they have numerous other area sensing applications for products such as fan control, door activation, temperature measurement and general energy measurement.
Polymer Optics’ designers have been at the forefront of PIR lens design for over 20 years. Our in-house developed ray-trace software can accurately predict the performance of the PIR lens before committing to tooling.
We also develop novel manufacturing methods for precision tooling manufacture and high quality moulded lenses.

Obsolete part re-manufacturing
Raytrace simulation showing predicted signal response across PIR detection zones. These simulations are used to ensure that an acceptable signal is available from all the Fresnel facets, to guide the product’s electronic design.
When a supplier “Murata” cancelled all production on one of their PIR Lens units, we were approached by customers to see if we had a drop-in replacement. Parts were needed as designed in and critical to their production.
POL was able to take their real world needs and engineer a solution that is unique to each customer, while still fitting within the working envelope.
We could have designed and built a copy part but as they were not using all the optical area, we saved them money on complex tooling by designing and tooling only the optical area needed.
So, we have gone from a complex multi zone Fresnel lens to a multi zone spot lens hence reducing tooling lead-times and costs.
Types of lenses
Small and compact, these lenses are suitable for numerous security and lighting applications, in the office, or around the home.
Lens pushes onto TO5 pyro to ensure correct focal length and orientation. Casing traps lens flange so that the lens is held securely.
