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.
Raytrace simulation showing PIR detection zones projected on to walls and ceiling. This type of simulation tool helps visualise the performance of the lens and confirms the product design performance.
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.
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.
