A laser is a special kind of artificial light. Its properties differ completely from those of ordinary light. Thanks to its directivity and monochromaticity, which mean that it moves in a straight line without spreading out very much, a laser’s power is concentrated and high-density. Some lasers are so powerful that they even can melt metal in an instant. For this reason, if laser operators neglect preventive measures despite knowing of these properties, they can face a high risk of injury. Of particularly serious concern, the impact of laser light on the eye is strong even at low power, and depending on its wavelength it could cause unexpected damage to the retina through concentration of light in the crystalline lens, resulting in worsened vision or other permanent harm to the functioning of the eye.
Tips on choosing LASER SAFETY
- Point of selection
- Choose laser safety glasses suited to each type (wavelength, output) of laser.
Note: General-purpose light-shielding safety glasses cannot protect against laser light.
- Operation target
- Work in, or near, places subject to irradiation by laser rays, such as laser welding, cutting, and machining.
- Application
- Laser machining (cutting, welding, marking, joining, etc.), laser measurement, laser therapy, etc.
Based on our core technology of controlling light, which we have been accumulating for over 100 years since our foundation, we have been developing industrial safety eyewear, including laser safety glasses, and various types of protective equipment.
Also, using our filter technology built up over 30 years, we have been pioneering the industry by developing dust masks and powered air-purifying respirators and continue to present new products to the market.
Moving forward, it is Yamamoto Kogaku's hope to support not only the bodily safety of workers but all aspects of people's lifestyles for safer, more comfortable living environments.
-
- Light control technology
- At worksites with welding, laser processing, and other such jobs, intense, yet invisible light like UV rays and infrared rays are emitted from high-output equipment in high amounts, harming workers' eyes. Yamamoto Kogaku products absorb, reflect, permeate, and polarize particular light and wavelengths for optional and various aspects of control, in turn offering workers safety and heightened performance.
-
- Coating technology
- Lens coating is a deciding factor in glasses functionality including work efficiency and vision safety. From the addition of fundamental anti-fogging and stain resistance abilities in lenses to offering reflection rates, wavelength attributes, and other light-related abilities, a variety of possibilities unfold relating to the environment of use and function requirements.
-
- Safety structure design
- Yamamoto Kogaku is the only manufacturer in Japan to consolidate in-house lens development grounded in specialized optical function and frame design based on ergonomics showcasing the full extent of the lens' capabilities as well as the consequent production and sale.
We offer safety products in line with numerous standards, including JIS (Japanese Industrial Standards), ANSI (American National Standards Institute), EN (Europäische Norm, or European Standard), and CE (Conformité Européenne, or European Conformity) marking.
-
- Filter technology
- Our high-performance filter technology, providing high filtration rate and low ventilation resistance, is employed in numerous products, such as powered air-purifying respirator PAPR, dust masks with respiratory assist devices, and disposable dust masks, which passed the Ministry of Health, Labor and Welfare's type certification (National Assay) and allows for a clear field of vision and safe breathing conditions for workers.
