3rd Opto­Net Inter­na­tio­nal Sum­mer School • Advan­ced Lens Design

2020 Nov 23 Mon

until Novem­ber, 27 2020 | all-day

Cur­rent notice:

In the con­text of the Corona pan­de­mic, the event has been reschedu­led from June to Novem­ber 2020. All already regis­tered par­ti­ci­pants will be infor­med shortly; the can­cel­la­tion peri­ods will of course be exten­ded. In any case, we will do ever­ything to ensure a suc­cess­ful and safe par­ti­ci­pa­tion. We will pre­sent a cor­re­spon­ding hygiene con­cept to you in good time. In this con­text it may be necessary to move the event to ano­t­her loca­tion (wit­hin Jena) or to restrict the num­ber of par­ti­ci­pants.

Pro­ven con­cept + fle­xi­ble trai­ning sche­dule + more prac­tice

As end users expect ever more sophisti­ca­ted per­for­mance, opti­cal sys­tem deve­lo­pers and manu­fac­tu­rers face incre­a­sing chal­len­ges. We are plea­sed to announce the 3rd Inter­na­tio­nal Opto­Net Sum­mer School ›Advan­ced Lens Design‹, which will once again pro­vide prac­ti­cal trai­ning at the hig­hest pro­fes­sio­nal level. It is aimed at tech­ni­ci­ans, engi­neers and rese­ar­chers invol­ved in the design of opti­cal sys­tems for ima­ging sys­tems who need more theo­re­ti­cal insight and prac­ti­cal expe­ri­ence in this field. The Sum­mer school will be con­duc­ted by the inter­na­tio­nally renow­ned expert Prof. Dr. Her­bert Gross from the Fried­rich Schil­ler Uni­ver­sity of Jena and his col­leagues.


Main topics of the semi­nar, which will be con­duc­ted directly with the com­mer­cial soft­ware Optic­Stu­dio, are pro­per­ties of opti­cal ima­ging sys­tems, aberra­ti­ons, opti­miz­a­tion and cor­rec­tion stra­tegy, qua­lity eva­lua­tion, asphe­res, cor­rec­tion of spe­cial degra­dati­ons, simple sys­tems, eye­pie­ces, relay and scan sys­tems, tele­scope sys­tems, camera sys­tems, zoom sys­tems, micro­scopic sys­tems, dif­fe­rent sys­tem types, tole­rance and adjus­t­ment.

With a revi­sed trai­ning plan and a 3+2 con­cept, we offer both basic trai­ning for begin­ners and advan­ced topics for expe­ri­en­ced opti­cal desi­gners. Optio­nal evening events are offe­red to fur­ther deepen know­ledge and prac­ti­cal skills.

The event will be held in Eng­lish.


The tea­ching team is led by Her­bert Gross, an inter­na­tio­nally reco­gni­zed expert in the field of opti­cal sys­tem design with more than 30 years of indus­try expe­ri­ence in lea­ding posi­ti­ons in the pho­to­nics indus­try and hol­der of a pro­fes­sor­s­hip. His rese­arch focu­ses on opti­cal sys­tems, their design, model­ling, simu­la­tion and per­for­mance eva­lua­tion as well as aspects of metro­logy and imple­men­ta­tion.



Par­ti­ci­pants should have expe­ri­ence using the OpticStudio/Zemax opti­cal design soft­ware and basic know­ledge of opti­cal design.

  • During the ›Basic Trai­ning‹ from Mon­day to Wed­nes­day par­ti­ci­pants will have the oppor­tu­nity to refresh fun­da­men­tal expe­ri­ence in the hand­ling of the soft­ware. Fur­ther topics will be Aberra­ti­ons, Opti­miz­a­tion, Asphe­res, Chro­ma­ti­cal cor­rec­tion, Mir­ror sys­tems and Cor­rec­tion methods. A short intro­duc­tion into Tole­ran­cing will com­plete the agenda.
  • The ›Advan­ced Trai­ning‹ on Thurs­day and Fri­day addres­ses more expe­ri­en­ced Opti­cal Desi­gners, who want to expand their know­ledge and skills in topics like Aberra­ti­ons, Dif­frac­tive ele­ments, Zoom len­ses or Micro­scopic len­ses. A main focus will be on Cor­rec­tion methods and Tole­ran­cing.
  • The ›Basic Trai­ning‹ and the ›Avan­ced Trai­ning‹ build on one ano­t­her and can be boo­ked both sepa­rate or com­bi­ned. For boo­king the whole trai­ning week we pro­vide attrac­tive con­di­ti­ons.

Please bring your own note­book equip­ped with a cur­rent Optic­Stu­dio pro­gram ver­sion. Soft­ware can not be pro­vi­ded.


The Sum­mer School will take place in Jena, the city of Ernst Abbe and Carl Zeiss who laid the foun­da­tion for modern optics 150 years ago. Since then the sci­ence city Jena has been shaped by inno­va­tive, light-based tech­no­lo­gies. Enjoy the spi­rit in the young uni­ver­sity town sur­roun­ded by a magni­ficent land­s­cape and well-known sights of Euro­pean history.


The regis­tra­tion is open. Reser­va­tions are pos­si­ble. Mem­bers from our natio­nal and inter­na­tio­nal part­ner clus­ters bene­fit from a con­si­derable dis­count.

Work­shop rela­ted costs, food and bever­a­ges during the semi­nar will be met by the orga­ni­zers. Con­fe­rence mate­ri­als, docu­ments and exer­ci­ses are inclu­ded in the con­fe­rence fee. Par­ti­ci­pants are kindly expec­ted to cover the costs for their indi­vi­dual tra­vel and accom­mo­da­tion. Please bring your own note­book equip­ped with a cur­rent Optic­Stu­dio pro­gram ver­sion. Soft­ware can be pro­vi­ded in par­ti­cu­lar cases.
