DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to laser reflected light viewing glasses, a laser reflected light viewing method using the same, and a blackout method using the same. This is used when the object to be irradiated is irradiated with laser light by the laser light irradiation device of (1) and the laser reflected light from the object to be irradiated is visually recognized.

[0002]

2. Description of the Related Art Heretofore, various operations have been performed by irradiating an object to be irradiated with laser light by a laser light irradiation device and using laser reflected light from the object to be irradiated as a guide. For example,
2. Description of the Related Art Black spotting work or the like at a construction site is performed using a laser spotting device as a guide for irradiation lines and irradiation points obtained by irradiating a wall, ceiling, floor, or the like with a laser beam by a laser marking apparatus.

[0003]

However, the object to be irradiated is irradiated with laser light by a laser light irradiation device,
When performing work by visually checking the laser reflected light from the irradiation object, when performing the work in a bright place such as outdoors, it is difficult to visually recognize the laser reflected light due to the influence of ambient light other than the laser reflected light. Therefore, there is a problem that it is not possible to carry out the ink marking work smoothly. That is, if the surroundings are bright, the pupil of the human eye is narrowed by the influence of the surrounding light, and the laser reflected light is also attenuated by the pupil, making it difficult to visually recognize the laser reflected light.

Accordingly, the present invention has been made to solve the above problems, and makes it easy to visually recognize laser reflected light from an object to be illuminated even in a bright place such as outdoors where ambient light is strong. Another object of the present invention is to make it easy to perform work using laser reflected light as a guide.

[0005]

Means for Solving the Problems In order to solve the above problems,
The laser reflected light viewing glasses according to the present invention are formed from a lens 1 that can transmit light having substantially the same wavelength as the laser reflected light obtained and irradiated by the laser light irradiation device, and absorbs or reflects light of other wavelengths. Have been.

[0006]

The glasses for viewing laser reflected light according to the present invention are formed of a lens 1 which can transmit light having substantially the same wavelength as the laser reflected light and absorb or reflect light of other wavelengths. When mounted when viewing the reflected light, the laser reflected light can be easily viewed.
That is, since the lens 1 absorbs or reflects light having a wavelength different from the laser reflected light, light having a wavelength different from the laser reflected light among the light existing around is absorbed or reflected, and the entire amount of light entering the human eye is reduced. In order to lower the pupil of the human eye, the pupil of the human eye is not narrowed and the lens 1 is formed so as to transmit light having substantially the same wavelength as the laser reflected light. It is possible to reach the human eyes with the same amount of light, so that the laser reflected light from the irradiation object can be easily visually recognized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, as one embodiment of the laser reflected light viewing glasses according to the present invention, a projection line 6 and a projection point 7 obtained by irradiating a red laser beam by a laser marking device 5 for irradiating a red laser beam. With reference to the drawings, a description will be given, with reference to the drawings, of laser-reflected-light viewing glasses used when performing blackout by visually recognizing the image.

In FIG. 1, reference numeral 1 denotes a lens, and the lens 1 is formed of a plastic sheet made of a red transparent acrylic resin so that a projection line 6 and a projection point 7 which are laser reflected light can be visually recognized. . The lens 1
Is attached to the goggle-shaped eyeglass body 2. A mounting means 3 comprising a belt that can be wound around the head is attached to the side of the spectacle body 2, and an air valve 4 for supplying and discharging air inside the goggles is provided on the upper part of the spectacle body 2. Is provided.

The laser reflected light viewing glasses of the present embodiment have the above-mentioned configuration, and can be irradiated with a red laser beam having a wavelength of 632.8 nm as shown in FIG. 2 by wearing the laser reflected light viewing glasses. The wall 8, ceiling 9, and floor 10 are irradiated with red laser light by a laser blacking device 5 composed of a natural helium gas laser, and the resulting irradiation lines 6 and irradiation points 7 are visually recognized. The case where the delivery is performed will be described below.

When the glasses for viewing laser reflected light of this embodiment are worn by the wearing means 3, the red light having a wavelength of about 632.8 nm is transmitted almost as it is because the lens 1 is red and transparent. Light having a wavelength is absorbed by the lens 1. Therefore, the light of wavelengths other than red among the light of various wavelengths existing in the surroundings is absorbed by the lens 1. On the other hand, the irradiation line 6 and the irradiation point 7, which are reflected light of a red laser beam having a wavelength of 632.8 nm, have a wavelength of 632.8 nm, so that they can pass through the lens almost as it is.

With this configuration, when the spectacles for viewing the laser reflected light are worn, the irradiation line 6 and the irradiation point 7 can be easily visually recognized. This has the advantage that the blackout work can be performed reliably.

In the above-described embodiment, the laser marking device 5 applies a red laser beam to the wall 8,
Projection line 6 and projection point 7 obtained by irradiating ceiling 9 and floor 10
However, the present invention can be widely used not only for performing the blackout operation but also for visually confirming the laser reflected light. For example, the present invention can be widely used in a field in which laser reflected light is visually recognized, such as horizontal alignment when mounting a signboard or the like, determination of a room partition, and the like.

In the above embodiment, the wavelength 63
A laser marking device 5 composed of a helium gas laser that emits a 2.8 nm red laser beam has a wavelength of 63
Although the case of irradiating a 2.8 nm red laser beam has been described, the present invention is not limited to this.

That is, the glasses for visualizing laser reflected light of the present invention can be used not only in the laser marking device 5 but also in any laser light irradiation device that emits laser light. For example, helium-neon (He-Ne) ), Argon (Ar)
Such as gas lasers, solid lasers such as YAG,
Alternatively, it can be used to visually recognize laser reflected light obtained by irradiation with various laser devices such as a semiconductor laser.

In the above embodiment, the lens 1 is made red and transparent so that the reflected light of the red laser light can be visually recognized. However, the lens 1 of the laser reflected light viewing glasses of the present invention is not limited to this. Instead, any lens may be used as long as it can transmit light having a wavelength substantially the same as the wavelength of light to be visually recognized and absorb or reflect light having other wavelengths. For example, wavelength 540n
When the laser reflected light by the green laser of m is visually recognized, it is sufficient if the lens 1 can transmit light having a wavelength of about 540 nm and can absorb light having other wavelengths. Specifically, it is green transparent or green translucent. Lens 1 may be used.
Furthermore, when the laser reflected light of a blue laser having a wavelength of 473 nm is visually recognized, a lens 1 that can transmit light having substantially the same wavelength as the wavelength of 473 nm and absorbs or reflects light of other wavelengths may be used. More specifically, any blue transparent or translucent blue lens 1 may be used.

Further, even when the reflected light of the red laser light is visually recognized, it is not limited to the case where the light having a wavelength of approximately 632.8 nm is visually recognized.
The laser reflected light viewing glasses according to the present invention can be used even when the laser reflected light of a semiconductor laser that emits laser light of 35 to 650 nm is visually recognized.

In the above embodiment, since the lens 1 is formed of a plastic sheet made of an acrylic resin, the lens 1 is not easily scratched and has advantages in terms of durability and weight reduction. However, the lens 1 is transparent or semi-transparent. Any material may be used as long as it is transparent. For example, glass may be used. In addition, even when the plastic sheet is formed of a plastic sheet, the plastic sheet is not limited to an acrylic resin, but may be of any kind. For example, if the plastic sheet is formed of vinyl chloride, there is an advantage that the cost can be reduced. However, if environmental aspects are taken into consideration, it is preferable to use an acrylic resin.

Further, in the above embodiment, since the eyeglass body 2 is formed in the form of goggles, all surrounding light entering the eyes is transmitted through the lens 1, so that it is easier to visually recognize. However, the eyeglass body 2 need not be formed in a goggle shape. That is, the mounting means 3 does not need to be a belt that can be wound around the head, and may be anything that hangs on the ear, one that is held by hand, or one that covers the head.

Further, since the air valve 4 is provided in the above embodiment, the air inside the goggle-shaped spectacle body 2 can be supplied to and discharged from the outside, so that the lens 1 does not fog during mounting. Although having advantages, the air valve 4 is not a requirement of the present invention.

[0020]

As described above, the laser reflected light viewing glasses according to the present invention are capable of transmitting light having substantially the same wavelength as the laser reflected light and absorbing or reflecting light having other wavelengths. Since it is formed, it is easy to see the laser reflected light when worn when performing various tasks using the laser reflected light as a guide. Can be obtained.
