Julius Muschaweck | JMO GmbH

Optical Engineering – Illumination


LED Whisperer & Colorimetry Pro


Bookings Currently Not Available on Odd Engineer (Pilot Concluded)

Other Expertise

  • Optical design for illumination (including LED primary and secondary optics, light guides, spotlights, surgery microscope lights, customized illumination for machine vision system needs, automotive headlamps, outdoor…& more!)
  • Colorimetry (how to drive multi-color LED engines to achieve a desired brightness and color point with maximum efficacy and/or color rendering)
  • First principle based feasibility analysis (Is there enough light? Is there enough space? Will fundamental laws of optics allow – or forbid – that specs can be met, given size and power constraints?)
  • Optical Modeling (how to simplify, but not over-simplify in simulation models)
  • Computer programming (compute things the simulation software won’t compute such as: user-defined components for LightTools, colorimetry toolbox, analyzing and modifying ray files… etc.)

Industry Specialties

Previous Optical Engineering Examples


For Companies

Schedule a call to talk through kicking-off an LED illumination design including:

  •  Defining meaningful illumination specs
  • Find out if your specs are reasonable under the size/power constraints
  • Learning which optical design architectures are possible
  • Choosing LEDs

Appointment N/A

For Other Optical Engineers

Chat with Julius if you need help understanding:

  • what etendue really is, and why it’s so useful 
  • how to model light sources and optical systems with extreme detail in LightTools
  • which optical materials to select for  a certain application
