Sci­en­ti­fic edu­ca­tion cen­ter recei­ves new »VELVET LED« pro­jec­tion tech­no­logy from ZEISS

ZEISS com­ple­ted the instal­la­tion of a new »VELVET LED« full­dome video sys­tem for the Chungbuk Sci­ence Cen­ter in the Korean city of Che­ongju in Sep­tem­ber. The sci­ence cen­ter con­sists of a pla­ne­ta­rium, an obser­va­tory and, a large exhi­bi­tion area with inter­ac­tive exhi­bits that focus on science.

Six ZEISS VELVET LED pro­jec­tors pro­duce full­dome images on the 25 degrees til­ted pla­ne­ta­rium dome. ZEISS VELVET tech­no­logy has been fit­ted to nume­rous pla­ne­ta­ri­ums for a good 10 years. The use of semi­con­duc­tor light sources is a new fea­ture of VELVET pro­jec­tors: the LEDs pro­vide a brigh­ter over­all dis­play with signi­fi­cantly impro­ved color bril­li­ance. As a result, cus­to­mers no lon­ger have to worry about paying for regu­lar bulb chan­ges. The excep­tio­nally high con­trast for the ZEISS VELVET pro­jec­tors is also retai­ned with the new LED genera­tion. »The abso­lutely black back­ground ensu­res that the starry sky of an ana­log pla­ne­ta­rium pro­jec­tor loses none of its natu­ral bril­li­ance and con­ti­nues to evoke an emo­tio­nal response in visi­tors,« exp­lains Mar­tin Kraus, Head of ZEISS Pla­ne­ta­ri­ums. First laun­ched in 2019, the new pro­jec­tors are now also being used out­side of Ger­many for the first time.

The ZEISS STARMASTER, a pla­ne­ta­rium pro­jec­tor from ZEISS, has been used to illus­trate astro­no­mi­cal rela­ti­ons­hips in the 16-meter dome of the pla­ne­ta­rium since 2001. In addi­tion to instal­ling the ZEISS VELVET video sys­tem, the com­pany also pro­vi­ded tech­ni­cal main­ten­ance of the ZEISS STARMASTER pro­jec­tor. A vir­tual pre­sen­ta­tion of the uni­verse has been added to the dis­plays of the tra­di­tio­nal pla­ne­ta­rium thanks to the new digi­tal pro­jec­tion sys­tem – on the basis of sci­en­ti­fic data and to enable the pos­si­bi­lity of pre­sen­ting shows and films in dome for­mat. The cor­re­spon­ding soft­ware and a selec­tion of cur­rent shows on mainly astro­no­mi­cal topics are also part of the scope of deli­very from ZEISS. The opto-mecha­ni­cal starry sky with digi­tal dis­plays is pro­jec­ted syn­chro­nously. ZEISS calls this tech­no­logy »True Black Hybrid-Planetarium«.

»For the Korean edu­ca­tion cen­ter, the abi­lity to teach sci­en­ces is key mis­sion for the future of the young genera­tion of the coun­try,« con­ti­nues Kraus. »Buil­ding on the foun­da­ti­ons of sci­ence and avail­able to anyone who’s inte­res­ted, pla­ne­ta­ri­ums and inter­ac­tive exhi­bi­ti­ons pro­vide easy access to advan­ced sci­en­ti­fic edu­ca­tion out­side the school environment.«


ZEISS is an inter­na­tio­nally lea­ding tech­no­logy enter­prise ope­ra­ting in the fields of optics and optoelec­tro­nics. In the pre­vious fis­cal year, the ZEISS Group gene­ra­ted annual reve­nue tota­ling more than 6.4 bil­lion euros in its four seg­ments Semi­con­duc­tor Manu­fac­tu­ring Tech­no­logy, Indus­trial Qua­lity & Rese­arch, Medi­cal Tech­no­logy and Con­su­mer Mar­kets (sta­tus: 30 Sep­tem­ber 2019).

For its cus­to­mers, ZEISS deve­lops, pro­du­ces and dis­tri­bu­tes highly inno­va­tive solu­ti­ons for indus­trial metro­logy and qua­lity assurance, micro­scopy solu­ti­ons for the life sci­en­ces and mate­ri­als rese­arch, and medi­cal tech­no­logy solu­ti­ons for dia­gnostics and tre­at­ment in oph­thal­mo­logy and micro­sur­gery. The name ZEISS is also syn­ony­mous with the world’s lea­ding litho­gra­phy optics, which are used by the chip indus­try to manu­fac­ture semi­con­duc­tor com­pon­ents. There is glo­bal demand for trend­set­ting ZEISS brand pro­ducts such as eye­glass len­ses, camera len­ses and binoculars.

With a port­fo­lio ali­gned with future growth areas like digi­ta­liz­a­tion, health­care and Smart Pro­duc­tion and a strong brand, ZEISS is shaping the future of tech­no­logy and con­stantly advan­cing the world of optics and rela­ted fields with its solu­ti­ons. The company’s signi­fi­cant, sus­tainable invest­ments in rese­arch and deve­lo­p­ment lay the foun­da­tion for the suc­cess and con­ti­nued expan­sion of ZEISS‹ tech­no­logy and mar­ket leadership.

With over 31,000 employees, ZEISS is active glo­bally in almost 50 coun­tries with around 60 sales and ser­vice com­pa­nies, 30 pro­duc­tion sites and 25 deve­lo­p­ment sites. Foun­ded in 1846 in Jena, the com­pany is head­quar­te­red in Ober­ko­chen, Ger­many. The Carl Zeiss Foun­da­tion, one of the lar­gest foun­da­ti­ons in Ger­many com­mit­ted to the pro­mo­tion of sci­ence, is the sole owner of the hol­ding com­pany, Carl Zeiss AG.
