safety & innovation under high time pressure - opsira for automotive

The latest designs, strict standards, efficient light utilization, and cost-efficient serial production are essential topics in the automotive industry. Focussing on these, opsira supports its customers in the development of standard light functions, advanced frontlighting systems, and ambient lighting. This means:

  • From the product draft to serial production: opsira development support is there to assist you throughout the entire process – and also on the topic of redesigning with new LEDs.

  • Realistic optical simulation and optimization: opsira lightlab provides high-quality ray data and measures scattering properties (BSDF), transmission and reflection of the materials used.

  • Comprehensive portfolio: The opsira spectroradiometers, the goniophotometer robogonio, and opsira's integrating spheres provide standard-compliant measurement data.

Optical Engineering. Light Lab. Test Systems. opsira is your full-service provider

Optics Design

Development of optical systems from the concept over the development, the production, and test of prototypes to series production.

Light Lab

Fast and precise light measurements of your light sources, LEDs and material samples carried out in the opsira lightlabs.

Optical Measurement Systems

Custom-made measuring systems for field work. The goniophotometer robogonio for example combines near-field, extremely fast far-field, and spectral measurement in one single, highly flexible system.

Test and Control Systems

The opsira eol (end-of-line) systems enable both the control of your production process and the quality of your products while they are manufactured, robot based if required.

diffusil® Diffusers

diffusil diffusers are made of a special opaque synthetic fused silica glass (99,999% SiO2). They are designed to create an almost perfect lambertian light output over a wide wavelength range in transmission and reflection.

What are Advanced Frontlighting Systems (AFS)?

The Advanced Frontlighting System is a dynamic optical system that ensures the best possible illumination of the road and the least possible glare for other road users, depending on parameters such as vehicle speed, steering wheel angle and a range of other ambient conditions.


What is ambient lighting?

Ambient lighting is part of vehicle lighting, or more precisely, interior lighting. Ambient lighting is characterised by the fact that it creates a very special ambience in the interior of the vehicle. This is often achieved by placing light sources indirectly and manufacturer- or model-specific lighting effects or colors. It makes passengers feel safer and can counteract fatigue.
