Product Overview

The Digitarium® Lambda is a digital planetarium system designed for use in fixed or semi-fixed domes. The Lambda is our highest resolution single lens system. The Lambda's Barco F70 projector combines Single Step Processing™ image processing with Texas Instruments' pixel shift technology to project a 3840x2400 source while using a native 2560x1600 DLP chip. 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 amazing 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.



Ease of Use
Setup Turn on projector. Turn on computer.
User Interfaces
Ergonomics Operator is untethered, and can use tactile wireless interfaces comfortably from anywhere in the dome. There is no laptop computer to hunch over or illuminate the dome with.
Multimedia Support Perspective, fisheye, and 360° spherical images and videos could not be easier to display anywhere on the dome and manipulate live.
Immersion Level Full. The audience is immersed in the simulation, and you can easily travel contiguously through time and space to demonstrate different concepts. Media are displayed within the simulation. No user interfaces need to distract the audience, and there are NO discontinuities. (Compare to other systems that break the immersion by requiring switching applications or software modes to show different locations or types of content.)
Simulation Software Exclusive Nightshade G3 universe simulator from Digitalis. Unlike desktop software, Nightshade G3 was designed for planetarians by planetarians.
Included Content
Scripting Capability All system features can be scripted using StratoScript by Digitalis. StratoScript is a simple, yet powerful macro language specifically designed for planetariums and even non-programmers.
Software Updates All system software is maintained by Digitalis, and updates over the Internet with new features and bug fixes are free for the life of your system. You never have to pay to go from version to version, which is a huge savings over many competing systems. Software updates run at your command, so they will never get in the way of using your system like can happen with Windows computers.
Training Online training via Zoom is provided with each purchase. Optional training academies are offered regularly for more advanced topics, like scripting. Optional onsite training is also available.
Technical Support Free standard technical support for the life of your system. Priority Support extended support options are available.
Warranty Three year limited warranty(Barco projector: three year, computer: two year). Contact us about extended warranty options.
Community Free membership in our Digitarium user community website to connect with other users around the world and share ideas and content. Online user group meetings are held regularly throughout the year via Zoom.
Projection Qualities
Maximum Dome Diameter  
The largest dome that we recommend for this system due to brightness.
11m / 36 ft
Fulldome Projection  
Fulldome projection offers the most immersive experience and the easiest teaching methods (no parts of the sky are missing).
Yes. 180° x 360° field of view for full sky projection from horizon to horizon with no cutouts.
Projection Uniformity  
Non-uniform projection, such as from spherical mirror projection, can be very obvious and distract from your teaching.
Consistent focus, contrast, brightness, and pixel sizes across the dome.
Pixel Diameter  
The number of pixels from one side of the dome to the other, passing through the zenith.
2400 (pixel shifting technology)
Projected Resolution  
The total number of unique pixels projected. The higher the number the more detail you can see, such as the phase of the unmagnified Moon from Earth.
4.5 megapixels
Pixels per Linear Degree of Sky  
This is another way of stating system resolution and how much detail can be shown. Consider that the angular size of the unmagnified Moon is only about half a degree, meaning it will be half this pixel count high on the dome.
Angle of Projection  
The projection angle from the central fisheye lens onto the dome. Angles less than 180° are desireable to keep the projector out of sight lines.
Lens Technology Exclusive Digitalis fisheye prime lens
Projection Technology  
DLP (Digital Light Processing) is a time-tested solid-state projection technology using micro-mirrors.
Base Projector Brightness  
For comparison purposes, this is the base projector brightness without accounting for using a fisheye lens.
7,500 lumens
Projector Contrast Ratio  
The contrast ratio is the ratio between a white and black scene. The higher the ratio, the more realistic the projection can look.
1,800:1 (up to 50,000:1 dynamic contrast)
Light Source Laser-phosphor
Illumination Lifetime 20,000 hours on high, up to 60,000 hours on lower settings
Audio Up to 7.1 audio output. Dante digital audio optional.
Computer Computer with powerful Nvidia GPU.
Rackmount, tower, or central enclosure computer options.
Storage Internal and external storage of 2 TB each. (This is separate from the solid state operating system drive.)
Modularity Computer, projector, and lens are modular so that each can potentially be upgraded separately.
Power 100-240 VAC, 50-60 Hz, 1900W
Regulatory FCC Class A, CE class A, RoHS compliant, UL or CSA marked components
Dimensions Secure enclosure: 31 inch (79 cm) diameter.
Installation height 41-72 inches (104-183 cm)
Other options include an open frame or lift mount.
Weight 240 lbs. (109.1 kg)
Total Cost of Ownership (TCO): Future Year Costs  
Any purchase can require significant ongoing maintenance and support costs that must be considered when making a buying decision.
Support Costs $0/year for standard support, more for Priority Support plans.
Hardware/OS Upgrades We suggest budgeting for computer upgrades every 5 years or so to stay current.
Consumables are items that are used up or must be replaced periodically.
Under $20/year for lens cleaning fluid/wipes and remote control batteries. No expensive lamps to replace, ever!
