Hembach Photonik – Experts for Optical Design and Analysis

Hembach Photonik GmbH is your development partner for illumination, sensor and imaging optical systems. It is located in Rednitzhembach, in the metropolitan area of Nuremberg, Germany. Since its foundation in 2011, Hembach Photonik has extended its fields of activity considerably, covering now most fields of classical optics.

Based on the long term experience of our staff, we develop products from the feasibility study to the virtual or real prototype. Also we analyze and improve the performance of existing optical systems and support your own design activities with customized software solutions. We fulfill your optical design and analysis requests within a wide range of application fields including, but not limited to:

  • Optical systems for space applications
  • Illumination systems for automotive and general lighting
  • Sensors for optical particle sizing, distance and position measurements
  • IR optics, from the near to the far infrared
  • Laser optics for various applications
  • Imaging optics for photography and machine vision

Optical design and development

Hembach Photonik offers the full development chain from concept studies, first order design, tolerancing and straylight analysis to the virtual and real prototype. For illumination, sensor and other non-imaging systems such as LED optics, light guides and free-form reflectors, we employ ASAP*), Solidworks*) as well as our own software. For imaging optics, such as camera lenses, telescopes and other high-end-systems, we count on ZEMAX*).

Straylight Analysis

As good as the imaging performance of an optical system may be: it is often the sensitivity to straylight that decides about its usability in real world. Whether light scattering from surfaces or bulk matter, ghost images, diffraction or thermal radiation – we help you to analyze and reduce straylight. Based on a rich experience with straylight, Hembach Photonik is renowned for its service quality and is one of the leading suppliers for straylight analyses in Europe– with customers in space industry, optical lithography, biomedical optics and other straylight critical applications.

Light Scattering Applications

Scattered light is an indispensable means for the contact-free, nondestructive analysis of materials. In illumination systems, light scattering can be used for guiding and homogenizing light; in most imaging systems, it is just unwanted straylight. Hembach Photonik looks back to more than twenty years of scientific and engineering experience in the field of light scattering. We help you to design and analyze optical and illumination systems in which light scattering plays an important role.

Key applications are:

  • Optical particle sizing and contamination detection
  • Application of volume-scattering materials for illumination optics (e.g., using diffusely scattering light guides etc.)
  • Measurement services for volume and surface scattering (ARS, BRDF, BTDF)

Custom software

Based on a steadily growing library of software solutions, we develop optical software, both for in-house use and for our customers, covering the following features and applications:

  • Differential ray tracing for precise radiometric analysis, including ghost analysis
  • Mie scattering and radiative transfer
  • Diffraction analysis
  • Baffle design tool for efficient stray light reduction
  • Data pre- and post-processing for large scale optical simulations
