The magnification is 6x, the effective diameter of the objective lens is 30mm, and the actual field of view is 8.4 degrees.
The prism uses high refractive index optical glass "Bak4" to suppress peripheral dimming. The lenses are made entirely of optical glass, without using plastic, to achieve a sharp central image.
We aimed for high light transmittance using a 7-9 layer multi-coat with extremely low reflection, which is normally only used on high-end binoculars.
As a result, the light transmittance through the binoculars is over 95% in most cases (see the graph in the photo), and in terms of brightness and color balance, it is comparable to high-end binoculars that cost over 100,000 yen.
The inside of the tube has been given ample matte coating to improve contrast.
Authentic binoculars with a diameter of 30mm. Although it has a bright, sharp visual appearance and is waterproof, we have kept the weight to around 400g, which is the bare minimum for carrying around. Hinode's recommended binoculars can be used for a wide range of purposes, such as observing stars, wild birds, and wild animals and plants. The brightness and sharpness of the view is outstanding compared to binoculars in the same price range. It's also waterproof, so you can safely use it outdoors. It is also sturdy so you can use it for a long time.
It's also great for admiring the scenery, observing birds and plants, and watching concerts and sports. The field of view is bright, so it is also recommended for astronomical gazing. It's lightweight at 482g, so it doesn't feel that heavy when you use it. It can be used comfortably by both men and women.
When placed in the soft case, it weighs a little less than a 500ml plastic bottle. If you find this inconvenient, please give up on using full-fledged binoculars of 30mm or more. We recommend using compact binoculars in the 20mm range (A3, N1, S1, etc.) for ease of use.
