Features of the OV-501 & OV-701
projection modules
Barco designed a projection module based on an innovative modular approach. The
concept of having a separate projection unit and illumination unit is unique and
results in an easy to maintain projection cube with superior picture quality. The
optical dimmer guarantees equal brightness and contrast across the display wall and
keeps the performance of the display constant over time.
•
Optimized for mission-critical operation
•
Engineered for use in 24/7 applications
•
Building blocks for fully integrated solution
•
Image quality optimization based on ergonomical studies
•
Low total cost of ownership
•
Single lamp projection
Luminance guidelines
•
All luminance values are given for
on-axis viewing. The 50% luminance
value will be present when viewing
under the half gain angles (see
‘screens table’)
•
All luminance values are measured at
6500 K
color temperature, normally
applied in control rooms for natural
lighting conditions
•
Luminance at other color
temperatures can be communicated
upon request
High-precision screen
•
High-contrast, even in bright ambient
light
•
Type of screen is selected based on
overall environmental conditions and
operational requirements
•
Excellent visibility under any viewing
angle
•
Patented screen modules with easy
mounting and narrow screen gap
•
All screens are double element
screens to avoid hotspotting on each
display
