The lens design in Bigscreen Beyond 2 significantly impacts the overall field of view (FOV) by providing several key improvements over its predecessor. Here are the details:
1. Wider Field of View: The new pancake lens design in Beyond 2 offers a wider field of view compared to the original Beyond. The diagonal FOV is reported to be around 116 degrees, which is an increase from the original's 93 degrees and even surpasses some competitors like the Meta Quest 3, which has a diagonal FOV of around 110 degrees[2][4][6]. This wider FOV enhances immersion and provides a more expansive viewing experience.
2. Edge-to-Edge Clarity: Beyond 2's lenses are designed to deliver "total edge-to-edge clarity," meaning that the image remains sharp and clear across the entire field of view, reducing distracting internal reflections and glare[1][2]. This improvement is crucial for maintaining a seamless and engaging VR experience.
3. Large Sweet Spot: The new optics also feature a significantly larger sweet spot compared to the original Beyond. The sweet spot is the area where the image is sharpest and most clear. A larger sweet spot means that users can move their eyes around without noticing significant drops in image quality, which was a limitation in the first model[2][4].
4. Reduced Glare: The design reduces glare, which can be distracting and detract from the overall VR experience. By minimizing glare, users can enjoy a more comfortable and immersive experience[2][3].
5. Adjustable IPD: Beyond 2 introduces an adjustable interpupillary distance (IPD) mechanism, allowing users to manually adjust the lens positions independently for each eye. This feature enhances compatibility for users with asymmetric IPD and ensures optimal image quality for a wider range of users[1][3]. However, users must manually enter their IPD settings in the software, as the headset does not automatically detect these adjustments[1].
Overall, the lens design in Bigscreen Beyond 2 offers a significant improvement in field of view, clarity, and user comfort, making it a compelling option for those seeking advanced VR experiences.
