    How to choose Laser Safety Goggles Protective Glasses?

    ①laser protection wavelength

    1.Diode Laser: Diode lasers can provide various wavelengths, including visible and near-infrared light. They are often used in laser printers, laser pointers, medical devices, and communication systems.



    2.532-nanometer Green Laser: Lasers with this wavelength are typically used in laser displays, biological microscopy, and laser therapy.



    3.633-640-nanometer Red Laser: These wavelengths are used in flow cytometers, scanning microscopes, and biomedical imaging.



    4.785-nanometer Near-Infrared Laser: Lasers at this wavelength are commonly used in Raman spectrometers, fluorescence spectrometers, and material detection.



    5.1064-nanometer Infrared Laser: This is a common infrared wavelength used in laser hair removal machine, laser cutting, laser marking, laser radar, and scientific research.



    6.1550-nanometer Laser: This wavelength is crucial for optical communications, used for signal transmission in fiber optic communication systems.



    7.10.6-micrometer CO2 Laser: This is a common wavelength used for laser cutting, laser welding, and laser engraving.
    ②OD(Optical Density)

    The term “OD” stands for “Optical Density,” It represents the percentage of harmful light passing through the glasses, with higher values indicating greater safety. :

    • OD1 = 0.1, which is equivalent to 10% transmittance.
    • OD2 = 0.01, which is equivalent to 1% transmittance.
    • OD3 = 0.001, which is equivalent to 0.1% transmittance.
    • OD4 = 0.0001, which is equivalent to 0.01% transmittance.
    • OD5 = 0.00001, which is equivalent to 0.001% transmittance.
    • OD6 = 0.000001, which is equivalent to 0.0001% transmittance.
    • OD7 = 0.0000001, which is equivalent to 0.00001% transmittance.

    These OD values represent the level of attenuation or reduction in the amount of light that passes through a material or optical system within a specific wavelength range. A lower OD value indicates higher transmittance, meaning more light passes through, while a higher OD value indicates lower transmittance and greater attenuation of light.



    ③VLT (Visible Light Transmission)

    VLT (Visible Light Transmission), in simple terms, refers to how much natural light can pass through eyewear. If a product is labeled as having a 41% VLT, it means that 41% of natural light can pass through. VLT can impact certain delicate operations, such as machinery maintenance and laser surgery.
