With the increasing use of laser technology, laser safety glasses are used as protective equipment to protect human eyes during laser operation. People will have questions: How often should laser protective glasses be replaced?In general, there is no fixed time standard for the replacement cycle of

The "CE" and "OD" on laser protective glasses are of vital importance, representing different but indispensable characteristics and certification information.The CE mark is a safety certification mark and a mandatory certification mark in the EU market. It indicates that the laser protective glasses

Let's first look at the relationship between OD value of laser safety glasses and protection range from the definitionOD value is optical density, which is the logarithm of the reciprocal of transmittance with base 10. The calculation formula is OD=log10(P0/P), where P0 is the incident light power a

Laser safety glass is a safety window that can effectively protect and filter lasers of specific wavelengths. There are mainly absorption-type laser protective glass and reflective laser protective glass. Because absorption-type laser protective glass is non-selective to light sources, it can provid

1. What is laser operation and its practical application areas① Laser operation refers to a series of activities involving laser generation, transmission, control and application using laser equipment. The generation of laser (Light Amplification by Stimulated Emission of Radiation) is based on the

The following key factors need to be considered when choosing the laser safety glasses that suit your needs:1. Determine the laser wavelength that needs protectionDifferent lasers emit different laser wavelengths, such as the common helium-neon laser wavelength of 632.8nm (red light) and the carbon

① Non-invasive or minimally invasiveIPL (intense pulsed light) is a non-ablative phototherapy technology, which means that it does not require invasive methods such as cutting and grinding to improve the skin or treat eye problems.For some eye applications, such as treating dry eyes, IPL mainly work

450 nm safety glasses do not provide 100% protection against all harmful blue light.1. Wavelength limitationThese glasses are specifically designed to target light around the 450 - nanometer wavelength. Blue light, however, encompasses a range of wavelengths from approximately 400 - 500 nanometers.

Laser hair removal equipment emits a laser beam of a specific wavelength, which can be selectively absorbed by the melanin in the hair follicles. The energy of the laser is absorbed by the melanin and converted into heat energy, thereby destroying the hair follicle tissue and making the hair lose it
