Dust-Resistant Structure Minimizes image Degradation

After a projector has been used for some time, dust particles that have entered the interior accmulate on the oftical components and lower performance. The PTLB78VE prevents this with a unique dust resistant design.This totally redisigned package has touchsensor controls that eliminate the gaps around conventional buttons and a lens cover. The design also incorporates a cover that protects the zoom/focus ring when not in use.these features combine to help reduce dust entry. inside the projector, the airflow is efficiently controlled by a structure that reduces contact between extrnal air and the optical components. This all works together with the high-performance Micro Cut Filter to minimize image degradation.
