LASER SAFETY EYEWEAR

Lasermate Group, Inc. provides a vast range of LaserShield polycarbonate laser safety eyewear - glasses and goggles - for a wide selection of wavelength ranges. We also provide an extensive collection of frame styles fitover and wraparound as well as filters for various applications, in particularly eye protection, visible alignment, and broadband intense pulsed light (IPL). Following the European and American standards, our LaserShield products are manufactured in the United States, and provide EN207/EN208/EC60825 and ANSI Z136.1 compliant and CE certified laser radiation protection. Most LaserShield laser safety eyewear meet international safety standards, including US ANSI Z136.1-.3 laser protection standards and Z87.1 impact standards, Canadian CSA Z386 and European EN207/208 standards.

For more detailed information, including price and specifications, and a step-by-step process on selecting your custom laser safety glasses or goggles, you may also download and view our laser safety eyewear product catalog on our Laser Safety Eyewear Product Catalog page.


HOW TO SELECT YOUR LASER SAFETY EYEWEAR

  Step 1: Filter

  • Determine the Optical Density (OD) for wavelength and power of the laser.

    • Consult the laser manufacturer or refer to laser manual for eyewear requirements.

    • Consider the conditions and needs of the use (i.e. eye protection, visible alignment, flashlamp/IPL).

    • Confirm that the filter will reduce possible energy exposure to below the Maximum Permissible Exposure (MPE).  

    Optical Density (OD) is a measure of the attenuation of energy passing through a filter, where the formulation is as follow: OD = log10(1/T) or T = 10-OD where OD is optical density and T is the transmittance. The higher the OD value, the higher the attenuation and the greater the protection level.

  • Consider the Visible Light Transmittance (VLT) of the Filter.

    • Consider the working environment.

    Visible Light Transmittance (VLT) is the percentage of visible light transmitted through a filter, calculated against the spectral sensitivity of the eye to daylight. Typically the higher the VLT, the lighter the color of the filter. High VLT is most suitable for low-light environments. VLT values below 20% is suggested to be used in well-lit working environments. 

    Other Terms:
    L-Rating
    in EN207 standard is used as the damage threshold of the eyewear material and requires actual laser stability testing for at least 10 seconds for CW mode of 100 pulses for pulsed modes. L-Rating consists of three components: a wavelength range, a laser mode designation and a scale number. The wavelength range engraved on the laser safety glasses or goggles is given in nanometers and is significant since the level of protection provided by the laser safety eyewear is wavelength dependent. Please refer to European standard EN207 for detailed information.

  SELECT FILTER BY WAVELENGTH (190nm~10600nm)

  SELECT FILTER BY APPLICATION

  Step 2: Frame

  • Select Frame style.

    • Consider whether users require a frame option that fits over prescription glasses or an adjustable frame to accommodate a variety of faces.

    • Ensure that the selected frame meets individual needs, and is face-forming and well-fitting with no gaps.
