Description

Introduction:
- The 25MM binocular telescope is equipped with APO focal front flat field optics, achieving high-definition 4K image quality and ensuring clear and sharp from the center to the edges. The body is lightweight to only 340 grams, and when folded, it is as small as a palm, balancing professional visual performance with portability, seamlessly integrating into outdoor observation and travel life.

- Three piece apochromatic technology, the lens includes lanthanide glass and ED lens, realizing APO technology, eliminating color difference for multiple colors, improving image clarity, and correcting the secondary spectrum after color correction. The color difference is reduced to almost imperceptible to the human eye, presenting a clear and sharp imaging effect with accurate color reproduction. Through APO apochromatic technology, excellent dispersion control can be achieved in both the center and edge areas of the image.

- 6 pieces and 4 groups of pre-focus flat-fielding technology. By optimizing the combination of field mirrors, the blurring and distortion of imaging edges can be effectively corrected. Truly achieved a clean and even game. Effectively reducing dark corners in the image and significantly improving the clarity of edge imaging.

- For RSBRIGHT 10-Nanometer coating: comprehensive multi-layer 10 nanometer coating reduces the light loss rate to 1.5% and significantly increases the overall light transmittance to 91%. Whether in strong or dark light, you can have a clear view and not miss any beautiful moments. With a peak transmittance of over 91%, the image is more vivid, transparent, and the imaging is sharper and clearer.

- Double-hinged folding design, easy to store and carry, with a reinforced structure that is more sturdy and durable; The extended metal rod design provides solid support for grip, compensating for the unstable grip caused by the slender barrel of small aperture telescopes.

- CNC precision machining technology, from parts to assembly, every step is exquisite.

- Small in size and high-performance, uncompromising for outdoor travel, compact, lightweight, and durable. Whether camping or hiking, lightweight and easy to carry, it can easily fit into any bag.

- REASUR exclusive connection kit, simplifying the connection steps to make filming easier, what you see is what you shoot, and recording beautiful life anytime, anywhere. It can be connected to all common mobile phones on the market for taking photos and videos.

- Wide-angle large eyepiece, 136M/1000M wide field visual enjoyment, allowing you to have a wider field of view, 21MM large eye cup, no eyelash sticking, no eye pressure, no black shadow on the eyes.
