Digitarium® Lambda Digital Planetarium System
The Digitarium® Lambda model is a digital planetarium system designed for use in permanent domes. The Lambda is our highest resolution single lens system. The Lambda's Barco F90 projector combines Single Step Processing™ image processing (at 5120x3200 pixels) with Texas Instruments' pixel shift technology to produce twice the pixel count of the physical DLP chip (2560x1600). This technology brings higher resolution at a more affordable price point to Digitarium systems.
The laser-phosphor illumination in this system provides bright, rich colors with an incredible 20,000+ hours of use without any lamps to replace. Laser life, like lamp life, is defined as when the projector output reaches half its original brightness. Laser module life is related to brightness, so running at 75% brightness can extend the expected life to an incredible 60,000 hours. That is 8 hours a day, every day, for more than 20 years! With the built in Constant Light Output feature you can define a less than maximum brightness and automatically hold this at the same constant brightness for as long as physically possible for reliable performance.
Full dome/full sky projection is available at a projection angle of 167 degrees. This is ideal for fixed domes, as the projection system is placed below the springline of the dome out of audience sight lines. Our elegant enclosure is adjustable in height at installation and keeps your system secure.
The Digitarium® Lambda model is designed for those who want the highest resolution and the best projection quality in a single-projector fixed Digitarium system. The Lambda's high resolution is invaluable for fulldome video shows, immersive environments, or scientific visualizations. Starfields will also look better, especially with the high contrast and our high quality proprietary lens.
The Lambda includes our high-resolution data sets of the Earth and solar system for spectacular planetary exploration with incredible detail.

|Maximum Dome Diameter||Around 47 feet/14m with a 50% reflectivity dome.
Brightness is the main issue, since the larger the dome, the larger the surface area the light from the projector must cover.
|Projected Resolution||4.02 megapixels (physical, overlapped)
|Field of view||180 degrees, full sky.
|Pixels per degree of sky||13.3 average (source)
|Angle of Projection||167 degrees
|Base Projector Brightness||11,800 lumens with non-fisheye lens. (Provided for comparison purposes with other systems. Actual brightness with a fisheye lens is significantly less due to not projecting the whole video rectangle and differing lens properties.)|
|Contrast Ratio||Up to 1,800:1 (projector also supports up to 50,000:1 dynamic contrast)|
|Laser life||Up to 20,000 hours on high. Up to 60,000 hours or longer on lower settings.
The projector uses laser phospor technology rather than lamps.
|Image Quality||Digitarium Lambda systems use our advanced proprietary lens design for superb projection quality.|
|Control Unit||Digitarium CU-1|
|User Interfaces Included
|Internal Storage||2000 GB expandable up to 8 TB or more.|
