      Tegevusaruanne 2025

      OÜ Difrotec on loodud 2009. aastal. Ettevõtte põhitegevuseks on optiliste mõõtmisseadmete tootmine. Ettevõttes on välja töötatud uus, ainulaadne ja patenteeritud tehnoloogia, mis aitab oluliselt paremini lahendada optika- ja elektroonikatööstuses esilekerkivaid mõõtmisprobleeme.

      Ettevõtte põhitooteks on difraktsiooniline interferomeeter (point diffraction interferometer)

      D7 – kõrgtehnoloogiline seade, mis mõõdab optiliste komponentide (nt läätsede, peeglite) ja süsteemide (nt teleskoobid, mikroskoobid) kvaliteeti. Difroteci interferomeeter on maailmas kõige kõrgema mõõtmistäpsusega (accuracy) 0.6 nm, kus 0.1 nm ehk 1 ängström on aatomi suurus. Lisaks interferomeetrile Difrotec pakub mõõtmisteenuseid ning tarkvara DifroMetric mõõtmistulemuste töötlemiseks.

      Oma tehnoloogia kaitsmiseks on Difrotec saanud 2019. aastal USA patendi No.

      10247359 ning 2020. aastal ka Euroopa patendi No. EP3187820. Difrotec on osalenud mitmetel rahvusvahelistel näitustel ja konverentsidel, kus esitles interferomeetrit D7, tegi ettekanded oma töö tulemustest ning rääkis tehnoloogia eelistest. Samal ajal ilmusid ka

      Difroteci teaduslikud artiklid ja ettekande presentatisoonid.

      Difrotec on müünud üle 10 seadme ja osutanud mitmed mõõtmisteenused. Kliendid on

      Saksamaal, Hollandis, USAs ja Hiinas. Kõige suuremad on Euroopa Kosmose Agentuur (ESA – European Space Agency), Brookhaven National Laboratiry (USA) ning Hiina juhtivad ülikoolid ja uurimisasutused Shenzhenis, Shanghais ja Hangzhous.

      2025. aasta tegevused olid enamasti suunatud tootearendusele. Difroteci meeskond on välja töötanud uue meetodi asfääriliste optiliste elementide mõõtmiseks. Selleks arendati ja täiendati oluliselt nii tarkvara kui riistvara. Novembris alustati uue meetodi patenteerimisega.

      Difrotec jätkas edukat müügitegevust Hiina turul ning valmistas uue süsteemi kliendile

      Shanghaist. Süsteem saadeti Hiinasse detsembris 2025.

      2025. aasta septembril osales ettevõtte meeskond ICAPI (International Conference on

      Applied Physics & Imaging) konverentsil, mille korraldas Tartu Ülikool, ja kus on Difrotec esitanud oma uuendatud D7 interferomeetri. Aasta lõpus alustas Difrotec koostöö

      Stuttgarti Ülikooliga. Koostöö raames planeeritkase tegeleda ühise tootearenduse ning müügiga Euroopa turul.

      Oma eduka tegevuse eest pälvis Difrotec 2025. aastal tiitli „Usaldusväärne ettevõte 2025“, mis jätkas eelmiste aastate trendi: „Usaldusväärne ettevõte 2024“ ja „Usaldusväärne ettevõte 2023“. Lisaks on Difrotec saanud sertifikaadi ja märgi „Äripäeva TOP 2025 ettevõte“ elektroonikatööstuses. Sellised tunnustused tõestavad Difroteci meeskonna pühendumust ja ettevõtte jätkusuutlikkust.

      Optical design is a specialized field that combines physics, engineering, and creativity to develop precise optical systems. These systems range from simple lenses to complex telescopes and cameras, all of which are foundational to numerous applications in science, industry, and daily life. Precision is paramount in optical design. The accuracy of an optical system determines its ability to produce clear, undistorted images, which is critical for applications such as microscopy, lithography, and astronomical observation. The Fundamentals of Optical Design At the heart of optical design is

      Interferometry is a powerful technique used to measure the wavefront of light with extreme precision. By superimposing waves, interferometry exploits the phenomenon of interference to extract information about the waves' properties, such as amplitude and phase. This method is pivotal in fields that demand high precision, such as optics, astronomy, and quantum mechanics. From its inception in the 19th century, interferometry has undergone significant advancements. The development of laser technology and digital signal processing has expanded its capabilities, leading to more accurate and

      Optical metrology, the science of measurement using light, has been a cornerstone in precision engineering, manufacturing, and scientific research. With the ability to measure features down to the nanometer scale, this field has enabled the development of advanced materials, microelectronics, and photonics. However, as industries push the boundaries of miniaturization and accuracy, the demand for measurements beyond the nanometer scale is rapidly increasing. Challenges in Current Nanometer-Scale Metrology While current optical metrology systems are capable of incredible precision, they face
