Aselsan tested the first IR sensor in the late 1990s and since then, Aselsan MGEO unit has continued its development by non-stop R&D and has expanded its technology to MWIR, QWIP, SWIR and NIR detectors, microbolometers, Image intensifiers. You treat this company like a teenager because it works to localize all the components, from the cooling systems to the filters which were imported before. I think you should not come up with such assertive statements on some issues that you do not have an idea.
About UV sensors, As you can read from post above, after German embargo was imposed on UV sensors in 2017 purchased from Germany, not only the UV detectors which you call very hard thing to develop but also the filter systems were completely localized within scope of the NEFIS project.
With a similar approach, a new project was started under the name of KÖRFIS, under the main contractor of TUSAŞ, with the subcontracting of Aselsan, Tübitak Bilgem Iltaren and the 1st Air Maintenance Command. In addition to the missile detection system with UV detector, Körfis which will operate in the IR spectrum, will enable missile detection from far ranges. All these capabilities in IR and UV technologies will be used in BEOS, IRST and FSS systems.
