|Polymer Optics Limited is a leading suppliers 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 management.Polymer Optics’ designers have been at the forefront of PIR lens design for over twenty 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.||New rapid manufacturing techniques allow fully working prototype lenses to be made within ten working days of design completion and a much faster route to final production tooling.Polymer Optics’ patented Free-form Fresnel (FF) technology ensures the lens detection zones are undistorted and highly focused for higher resolution and more reliable zone sensing.These ground-breaking techniques improve our design and manufacture and ensure we remain at the forefront of the PIR industry.
Raytrace simulation showing PIR detection zones projected onto 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.
Conventional Fresnel lens gives distorted zone image.
Pol Fresnel lens gives undistorted zone image.
|POL’s new Free-form Fresnel (FF) lens technology helps to reduce distortion and improve lens focal properties.|
Using POL’s Free-form Fresnel (FF) lens technology, it is now possible to make high performance flat lens arrays, which previously could only be achieved in 3D formed lens products. POL has used this new technology in a 31 detection zone PIR lens array called the FF31 and is available as a standard product. Part number 452
Previously it was only possible to maintain zone definition by tilting the Fresnel facets, meaning that the lens had to have a 3D appearance.
|Using POL’s new lens facet design, it is now possible to create a more aesthetically pleasing flat lens, which can be flush fitted into low profile wall and ceiling mounted detectors.|
The latest computer optical design and ray trace programs with optomechanical innovation are used to take full advantage of plastics materials. Complex optical surfaces combined with integral low cost assembly features.
SLA (Stereolithography), SLS (Selective Laser Sintering), Clear SLA, SLA to Vacuum Casting, Direct Machining and Tooling options.
Proven optical quality toolmakers are chosen and assisted by mould flow analysis to optimize the tool. Our specialist toolmakers are skilled in optical surface generation and polishing.
Our moulders are trained in the art of optical moulding. Mould flow process analysis and thorough F.M.E.A. is controlled by the Project Manager to ensure quality and quantity.
Our integrated approach to design enables optical components to become part of the total solution, including how they interface with the other non-optical components.
Plastics optical components can be coated in poly-siloxane and acrylate based resin blends to impart more robust properties.

Polymer Optics “Modular LED Optics”® design, based on a patented hexagonal format, allows maximum packing density and assembly flexibility for a wide range of applications.
We have also developed specialist optics for the latest range of high power UV LEDs emerging onto the market. These are made from high quality optical silicone to give excellent UV transmission with no long term degradation. See POL’s Silicone Optics page for further details.
We design and supply a comprehensive range of high quality, standard products for use with most world-leading LED devices
Hybrid Reflector design uses a central lens to collect and collimate the on-axis light from the LED.
Our expertise in efficient light control in Lightguide assemblies, enables a lower number of LEDs to achieve the maximum performance.
Free-Form optics are a relatively recent development which offer a step change in the way wide areas are illuminated by LEDs.
Our "engineering with light" approach allows us to provide product solutions for all applications across the whole spectrum from Visible to Infrared.
Developed tooling techniques enable us to produce precision optical surfaces with optical apertures of less than 1mm in diameter, required for miniature camera lens applications.
Our design approach, using light scattering pattern techniques, have enabled us to provide high efficiency display illuminations with very compact space envelopes, which use the minimum of light sources and electrical power consumption.
Our experience in designing and developing ophthalmic products, enables us to provide precision, impact resistant, eye protection optics for applications such as: fire protection, motor cycle visors, industrial PPE and military systems.
Polymer Optics have designed and manufactured a range of optics for street lighting, to meet both the ME and S class regimes of EN13201-2 in Europe and the requirements of IESNA RP-8-00 in the USA.
Emergency Lighting and Visual Alarm Devices are applications where light from an LED has to be efficiently distributed over a wide area. POL’s free form optics technology is particularly suited for applications which require wide area illumination.
POL can now provide advanced optical product design and rapid manufacture in the latest silicone resins to gain design and cost advantages in our customers’ applications.
Our patented prismatic colour mixing optic was introduced to enable good colour mixing, for narrow beam angle systems, using three discrete LED sources.
Brand named “GloWorm®”, the novel lightguide technology enables the light projected from a simple lightguide to be redirected and shaped
