Chal­lenges & Solu­ti­ons for Optics Design

The semi­nar will pro­vide com­pre­hen­sive insight into the phy­sics and mathe­ma­tics of illu­mi­na­tion optics and will equip par­ti­ci­pants with a »tool­box« of methods and design ele­ments. A num­ber of arche­typal examp­les will be used to explain how pro­blems can be ana­ly­zed using basic prin­ci­ples and how these insights and the tool­box can be used to create good design approaches.

KEY POINTS

• Opti­cal fun­da­men­tals (ray optics)
• Radiometric/photometric quan­ti­ties, inclu­ding moti­va­tion and measurement
• Phase space: what is it?
• Pho­to­me­tric quan­ti­ties in phase space
• Light sources, and how to model them
• Simu­la­tion of illu­mi­na­tion opti­cal systems
• Colo­ri­me­try and color mixing
• Design methods / arche­typal design approaches
• Arche­typal design pro­blems and their solution

TARGET GROUP

The semi­nar is aimed at opti­cal desi­gners, deve­lo­pers and engi­neers who deal with illu­mi­na­tion optics in the course of their work and the­r­e­fore want to gain a deeper under­stan­ding of light for illu­mi­na­tion and its prac­ti­cal application.

METHODOLOGY

In the semi­nar, both fun­da­men­tals and in-depth topics are dealt with in a struc­tu­red and prac­ti­cal man­ner. Many exer­ci­ses and small expe­ri­ments are an inte­gral part and con­tri­bute to a deeper under­stan­ding. Indi­vi­dual ques­ti­ons and pro­blems of the par­ti­ci­pants will be discussed.

TEAM OF SPEAKERS

Phy­si­cist Julius Muscha­weck has been invol­ved in opti­cal design for illu­mi­na­tion for over twenty years. After a stay at the Uni­ver­sity of Chi­cago as a Visi­ting Scho­lar  with Prof. Roland Win­s­ton (known as the foun­der of Noni­ma­ging Optics), he co-foun­ded an opti­cal engi­nee­ring ser­vice com­pany (OEC) that pio­nee­red free­form optics. At OSRAM, he later held the posi­tion of Senior Prin­ci­pal Key Expert and coor­di­na­ted over 100 OSRAM opti­cal desi­gners world­wide. He then moved to ARRI, the lea­ding manu­fac­tu­rer of film came­ras and lumi­n­aires, as Prin­ci­pal Opti­cal Sci­en­tist. Julius Muscha­weck curr­ently works as an inde­pen­dent con­sul­tant pro­vi­ding illu­mi­na­tion optics solu­ti­ons to indus­trial cli­ents. He is the aut­hor of over 25 sci­en­ti­fic publications.

Julius Muscha­weck is sup­ported by Dr. Hen­ning Rehn. The phy­si­cist with a PhD, who worked in Jena until 2001, first at the Fried­rich Schil­ler Uni­ver­sity and later at Carl Zeiss, has out­stan­ding know­ledge in the design of illu­mi­na­tion optics. From 2001–2018, he was active in Lamp Deve­lo­p­ment and LED Pro­ducts at OSRAM, among others, before moving to Switz­er­land in 2018.

SEMINAR STRUCTURE – MODULES

Module 1 · Colo­ri­me­try

• get to know and under­stand the com­mon color spaces, incl. CIE 1931 XYZ
• addi­tive color mixing and LED binning
• cal­cu­la­ti­ons of which LEDs are nee­ded in which pro­por­ti­ons to achieve a desi­red color and brightness
• using the JMO Mat­lab® Spec­trum Library (open source – for Mat­lab users)
• Color ren­de­ring index (CRI), dis­ad­van­ta­ges and limitations
• Using dif­fe­rent mea­su­res of color dif­fe­rence to assess homogeneity

Module 2 · Under­stan­ding light

• Con­cept of Eten­due & appli­ca­tion to prac­ti­cal problems
• Cal­cu­la­ting eten­due even in com­plex situa­tions using com­mer­ci­ally available ray tra­cing software
• Lumi­nous flux, lumi­nous inten­sity, illu­mi­nance and luminance
• Cal­cu­la­tion of lumi­nance of com­mer­ci­ally available LEDs from data sheet infor­ma­tion and use in opti­cal design
• Use of lumi­nance, lumi­nous flux, and eten­due for the fea­si­bi­lity of an illu­mi­na­tion optics pro­blem and for design approaches

Module 3 · Opti­cal Ele­ments & Architectures

• Buil­ding blocks of illu­mi­na­tion opti­cal systems
• Use of »design pat­terns« (approa­ches to solve typi­cal pro­blems) for light­ing optics problems

Module 4 · Mode­ling Light Sources & Light­ing Systems

• Use of light source models
• Buil­ding well-func­tio­ning light source models inclu­ding spectra
• Monte Carlo ray tra­cing software
• Mode­ling opti­ons for sur­faces and mate­ri­als and how to eva­luate them
• App­ly­ing con­cepts from Module 2 to mode­ling light sources and systems
• Mode­ling opti­ons of opti­cal effects

The four course modu­les can be boo­ked indi­vi­du­ally or as a block. Since we expect inter­na­tio­nal par­ti­ci­pants, the cour­ses will be held in English.
