Opto­Net Semi­nar – Illu­mi­na­tion Optics

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

Phy­si­cistJulius Muscha­weck  has been invol­ved in opti­cal design for illu­mi­na­tion for over twen­ty­five 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, tog­e­ther with Hen­ning Rehn, 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 byDr. 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

Part 1 Under­stan­ding light | Mon­day, 24 March 2025

• 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

Part 2 Mode­ling light sources & light­ing sys­tems | Tues­day, 25 March 2025

• Use of light source models
• Buil­ding well-func­tio­ning light source models inclu­ding spectra
• Monte Carlo ray tra­cing software
• Mode­ling of sur­faces, mate­ri­als and opti­cal effects

Part 3 Opti­cal Ele­ments & Archi­tec­tures | Wed­nes­day, 26 March 2025

• Buil­ding blocks of light­ing optics sys­tems – how do they trans­form the light beams, and what should be con­side­red in the design
• Use of ›design pat­terns‹ (solu­ti­ons for typi­cal tasks) for light­ing optics tasks.

Since we expect inter­na­tio­nal par­ti­ci­pants, the cours will be held in English.
