The University of Helsinki in Finland has purchased 17 Sony laser projectors for its presentation spaces.

The University of Helsinki, founded in 1640, is an international academic community of 40,000 students and staff members. It operates on four campuses in Helsinki and at 15 other locations in Finland. The properties are owned by Helsingin Yliopistokiinteistöt Oy and the University of Helsinki Funds. The university operates in a total of 319 buildings, and video projectors are used in around 400 facilities.

Short lamp lifespan is often the main problem according to Jyri Poittinen, ICT coordinator responsible for AV technology at the university. Projector maintenance is scheduled for summer, but lamps may still need to be replaced during the semester. Lamp-based projectors are also slow to turn on and off, which interferes with efficient teaching.

"Initially, the university placed an order for 10 4,000 lumen Sony VPL-FHZ55 laser projectors. Some of them were used for especially demanding educational purposes in the faculty of medicine,” said Jyri Poittinen, ICT coordinator.

The next order comprised seven VPL-FHZ700L projectors. These found their place in large halls and auditoriums where the projectors' colour light output of 7,000 lumens makes it possible to keep normal lighting on during presentations. The equipment was supplied by Sony supplier S-Professional Oy in co-operation.

Two of the biggest challenges faced by the University of Helsinki in their largest facilities were the maintenance resources needed to deal with the short lifespan of projector lamps. The promised lifespan of Sony's laser projector light sources is 20,000 hours, which is estimated to at least six years of operation at the university. The flexibility of the projectors also opens up new possibilities to the university for both presentations and video calls.
