Varjo

Varjo is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Varjo rather than just read about it. In short: Varjo Technologies Oyj, commonly referred to as Varjo, is a Finnish manufacturer of virtual reality and augmented reality headsets. The company was founded in 2016 by former Nokia and Microsoft executives.

Key takeaways

Varjo belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Varjo to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Varjo from memory before moving on to harder problems.

Reference excerpt

Varjo Technologies Oyj, commonly referred to as Varjo, is a Finnish manufacturer of virtual reality and augmented reality headsets. The company was founded in 2016 by former Nokia and Microsoft executives. Varjo specializes in developing high-resolution devices that offer clarity greater than devices typically sold to consumers. The company's first head-mounted display, Varjo VR-1, was launched in February 2019, and it was followed by Varjo VR-2 and VR-2 Pro models in October 2019. Varjo's first device with camera passthrough, Varjo XR-1 Developer Edition, was released to market in December 2019. The third-generation products, Varjo XR-3 and VR-3, were launched in December 2020. The virtual reality headset Varjo Aero, the company's first and only product available for consumers, was released to market in 2021. The company's fourth-generation headsets, the Varjo XR-4 Series, were announced in 2023 and refreshed for demanding simulation training in October 2025. Varjo has raised over $200M in funding.

History Varjo was founded by four people in 2016 at Helsinki, Finland.

Founders Niko Eiden, co-founder. Also, a CEO of Pixieray, Computers and Electronics Manufacturing company that specializes in optics. He studied at Helsinki University of Technology. Klaus Melakari, co-founder. He has 20 years of experience in R&D, system design and technology. Previously Head of Computational Vision Systems at Microsoft Mobile, Distinguished architect at Nokia. Klaus holds a M.Sc. in Electrical and Electronics Engineering at University of Oulu. Roope Rainisto, co-founder. He has 15 years of experience in concepting and UX design. He is the Previous principal designer at Microsoft and Nokia, Head of computational vision UX at Microsoft Mobile. He is also an Inventor in 40+ patents. He has a M.Sc. in Technology, Information networks. Urho Konttori, co-founder. He is a product innovator and program manager who has over 15 years of experience in designing, engineering and managing large-scale hardware and software projects at Microsoft and Nokia. He has been responsible for scouting, evaluating and defining high consumer value innovations such as novel cameras, see-through touch-screen fingerprint and VR headset technologies in more than a dozen mobile products, resulting in over 10 patents. He has also led the development of multiple operating systems, including the Linux-based Nokia N9 and N900 OS. Urho holds a B.Sc. degree in Algorithms.

Funding Varjo has raised over $200M in funding. Their latest funding was raised on Aug 13, 2025, from defense technology company THEON. Those who invested in Varjo include Foxconn, NVIDIA, EQT Ventures, Volvo, Atomico, Mirabaud, Tesi, Lifeline Ventures, European Bank, Nordic Fund, etc. Varjo's customers include defense and aviation industry leaders such as Boeing, Lockheed Martin, Rheinmetall, BAE Systems, Lufthansa Aviation Training, and several military forces, including Finnish Air Force, Slovenian Armed Forces, and the Royal Australian Air Force.

Worked examples

Example 1 — a first encounter with Varjo

Start with the simplest possible case. Write down what Varjo claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Varjo before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Varjo ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Varjo

In research: Varjo appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Varjo in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Varjo is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2016 establishments in Finland, Augmented reality, Electronics companies established in 2016, so understanding it makes those chapters shorter.
In everyday life: Look for Varjo outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Varjo in simple terms?

Why does Varjo matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
