How much do you know about motorcycle rearview mirrors?

 

Some motorcyclists think they don't need rearview mirrors. Because their speed is faster than the people and vehicles around them. In order to show this, some people simply remove the rearview mirror, which is quite unsafe. According to statistics, a large proportion of motorcycle traffic accidents are caused by collisions with the rear vehicle or vehicles coming from the rear.

Therefore, the correct selection of motorcycle rearview mirrors plays a very important role in the riding safety of riders.

There are two types of mirrors: surface mirrors and inner mirrors.

Many imported cars use surface mirrors, while NAPOLEON mirrors and genuine mirrors in domestic cars mostly use inner mirrors.

Since the surface mirror does not pass through the glass surface, no reflected image will appear in the reflector, and the difference between the real image and the mirror image is small, which is its advantage. However, since the reflective material is on the surface, it is easy to scratch the mirror surface, and there is a disadvantage of low durability.

On the other hand, compared with the surface mirror, because the glass is transmissive, the outline of the mirror image in the inner mirror is reflected inside the glass. However, since the reflective material is protected by glass, the durability is greatly improved and it can be multi-layered, so it is possible to make mirrors with added value, such as anti-glare mirrors and blue mirrors, etc.

Reflective materials of mirrors
The reflective materials of mirrors are mainly aluminum mirrors and chrome mirrors.

Chrome-plated chrome mirrors are used for surface mirrors.

And there are two main types of inner mirrors: aluminum vapor-deposited aluminum mirrors and chrome-plated chrome mirrors.

NAPOLEON mirrors that are not anti-glare mainly use aluminum mirrors.

The reason for using aluminum inner mirrors is that aluminum mirrors have very high reflectivity compared to chrome mirrors.

The reflectivity of chrome mirrors is slightly lower, about 60%, while the reflectivity of aluminum mirrors exceeds 90%.

Since NAPOLEON mirrors improve the quality of the glass itself used in the mirror, the distortion of the mirror image is small at each stage, and due to the high transmittance, it is brighter and easier to see than low-cost mirrors.

When it comes to mirrors, silver mirrors are common, but there are also colored mirrors for dressing up and anti-glare. An ordinary aluminum mirror consists of three layers: glass, reflective film, and protective film. Chrome mirrors do not require a protective film. Well, in the case of a colored mirror, it consists of three to five layers. It is arranged in the order of glass, adhesive, and reflective material, but two layers of connecting material are added because the coloring material does not require a connecting material.

Most colored mirrors use titanium as a coloring material. Titanium is the determining factor in the color composition, and it changes from blue to magenta to rainbow colors, as shown in the burnt color of the titanium muffler, but we use it to adjust the color. By setting the coloring titanium in front of the reflective material, the mirror surface is given color.

* In addition to it, there is also a colored mirror. By coloring the glass to change the color of the mirror, it can be manufactured at a low cost. However, when the color is mixed into the glass, the purity is reduced, resulting in glare caused by bubbles and other diffuse reflections, as well as image distortion. In order to improve the performance of the mirror, the purity of the glass is primary! NAPOLEON mirrors are high-quality mirrors with no impurities in the glass.

Curvature of the mirror As for the curvature of the mirror, the smaller the R, the smaller the mirror image, but the wider the viewing angle. Conversely, when R becomes larger, the mirror becomes larger, but the angle of view becomes narrower.

The curvature R1300 is the mainstream, but many NAPOLEON mirrors adopt R1000, and the design is designed to make it easier to confirm the blind spot in the past by using a wide-angle mirror. In addition, since the vertical field of view is widened, there is no need to fine-tune the rearview mirror even if the riding posture is slightly changed during a long trip. The NAPOLEON mirror is a safe and comfortable mirror because you spend less time looking at the rearview mirror to observe the road conditions behind.

RAY SAVE
About the wavelength-sensitive anti-glare function
Although it is a high-reflectivity NAPOLEON mirror, the visible light that people feel has a peak that is easily felt as shown in the figure below, so it is not always a good idea to install a bright mirror. The RAYSAVE mirror is a mirror with anti-glare performance by cutting off the part that makes people feel glare. This system prevents glare by reducing the reflection of the visual high sensitivity wavelength of 450nm to 600nm.

The visual sensitivity of bright vision and night vision is as follows.

In light, the sensitivity to yellow is higher, and in dark places, the sensitivity to blue is higher.

The wavelength-sensitive anti-glare function is a function that reduces the reflection of yellow wavelengths and uses the low reflectivity of chrome mirrors to reduce the overall reflectivity, thereby exerting an anti-glare effect.

How is it different from conventional OPTICS?

Conventional OPTICS has anti-glare performance and is sensitive to mirror images that produce natural colors, but RAYSAVE has high reflection in OPTICS, further improving the anti-glare performance from yellow to red, suppressing some reflectivity, and improving the reflectivity of blue wavelengths that are effective in dark places (the overall reflectivity is increased by 10%). In addition, the mirror image is made clearer by suppressing contrast.

With the evolution of light sources, there are more and more headlights with sharp light such as HID and LED, but RAYSAVE has enhanced anti-glare performance.

In addition, by significantly improving the manufacturing method, the deformation of the mirror edge is eliminated, and the diffuse reflection generated in the mirror when the headlight glare in some conventional products is suppressed.
