Photometry
Our range of offers
Several years of presence on the automotive scene have earned FAKT's photometric department a staff of expert technicians with more than 10 years' experience in homologation services. In fact, FAKT is a reference laboratory for the E24 approval authority in the photometric field. Photometric approvals pertain to a wide range of devices: from headlamps to rear lamps, for car/motorbike/bicycle, from special warning flashing lights to reflex reflectors, from advance warning triangles to registration plate illuminating devices, up to filament and gas-discharge lamps, headlamp cleaners, smart lighting systems (such as AFS), etc.
The large variety of devices FAKT can test and approve is equally matched by the wide range of certificates/approvals we are authorised to issue and/or assist you in obtaining.
For OEM manufacturers especially, the standard requirements of UNECE approvals or to North America/Canadian federal laws (FMVSS108 / CMVSS108) are no longer sufficient. Further need for approval according to the Taiwan directives (VSCC), Indian Standards (AIS) (in order to achieve TACs (Type Approval Certificates)) and Chinese GB Standards to obtain CCC certificates and Printing Permissions is now indispensable as well.
Furthermore, we can test and report in order to be
able to obtain approvals according to the StVZO (German
road traffic legals - ABG national approvals) for bicycle
lights, dynamo, rear warning panels, special warning flashing
lights, etc.
All the photometric (and also mechanical, chemical and environmental) tests are entirely carried out in our laboratories, giving an obvious advantage to the customer in terms of real-time communication of the approval process status and careful evaluation of the homologation workflow.
The photometric laboratory
Our photometric laboratory is equipped with modern instruments and technologies. These include:
goniometer- photometric head
- colourmeter
- retro-reflectometer
- luminance meter
- integrating sphere
- spectrometer
- mirrors for reflectance measurements
- optical benches for light diffusion and wear tests
Our service
includes complete customer care. Customers are
only required to provide the test samples along with
matching fixtures and relevant technical information.
In order to make the collection of these technical details easier, a dedicated form was created for each kind of device. You can download the form regarding the approval of lighting and light-signalling devices here. In addition to standard approval testing, we can, at the customer's explicit request, perform tests according to the specifications of automotive industry manufacturers. We can also provide assistance in more specific evaluations, like comparing measurements made at different distances, determining the retro-illuminating value, creating 3D isoline representations, and much more.
