The Ultra Pre­cis­ion Manu­fac­tu­ring of Asphe­res and Free­forms (UPM) work­shop has brought tog­e­ther the inter­na­tio­nal ultra-pre­cis­ion com­mu­nity in Jena since 2010. Held bien­ni­ally, it is a well-estab­lished plat­form for exch­ange in opti­cal manu­fac­tu­ring, metro­logy, and sys­tem inte­gra­tion.

Orga­nised by Opto­Net e.V.  with Fraun­ho­fer IOF, UPM focu­ses on the fabri­ca­tion and cha­rac­te­riza­tion of asphe­ri­cal and free­form optics, com­bi­ning sci­en­ti­fic depth with indus­trial rele­vance.

By con­nec­ting key play­ers across rese­arch and indus­try, UPM streng­thens Jena’s role as a glo­bal hub for pho­to­nics and ultra-pre­cis­ion engi­nee­ring.

In 2026 we will focus on

• Free­form optics for novel appli­ca­ti­ons
• Mid spa­tial fre­quency errors
• Free­form opti­cal sys­tems and
• Manu­fac­tu­ring and cha­rac­te­riza­tion of free­form sur­faces
