The panda telescope is developed and produced by Yunnan North Optical Electronics Group Co., Ltd. The predecessor of the company was founded in 1936 as the state-owned No. 298 Factory, as the earliest and largest comprehensive precision optical instrument factory in China, it had produced military optical instruments and equipment, made important technical contributions to the War of Resistance against Japan, and created a precedent for China's optical industry. Up to now, it has been deeply accomplished in the research and application of precision mechanical, optical, electronic, infrared, low-light, and thermal imaging technologies, and has a complete product layout in telescopes, microscopes, medical instruments, low-light night vision devices, lenses, photometer accessories, etc.
 
Among them, binoculars are mainly for the low-end market, including 1P Elvis, 80P anniversary model, new era, autumn tour and other most series of models are sold within 1,000 yuan, the objective lens diameter from the smallest 25mm to the largest 60mm, the magnification from 7 times to 20 times, rich specifications to choose can leave consumers with greater choice, of course, the magnification is not too large, otherwise it is easy to find the target, and the jitter phenomenon is serious, affecting the vision, the sense of vertigo is strong.
 
The military standard series 98 type 10×50 is the flagship model of the panda, with a price of about 2000 yuan. This model adopts the Paul prism system, because the reflection point of the light in the prism is one less than that of the roof type, and the BAK4 material is selected, and the multi-layer composite green film is selected, so the light transmittance has been improved, and the field of view is relatively wide, but it has the shortcomings of the bulky appearance of the Paul prism, and the portability has been weakened.
 
German and Japanese optical binoculars, its transmittance can maintain a first-class level of 94% to 99%, compared with the Panda's coating technology, there is still a significant gap, in order to eliminate the influence of stray light as much as possible, some models also spray matting paint on the inner wall of the objective lens to reduce the scattering of light in the lens barrel. It is worth affirming that the Panda binoculars are fully humanized in product design, such as the visibility handwheel can improve the clarity of the target, and after the first adjustment, there is no need for secondary adjustment when observing other targets; The design of the spiral eye mask is convenient for users who wear glasses.
