Laser Safety Goggles

Choosing Correct EYE Protection

Filter -- OD, damage threshold and Visible Light Transmittance (VLT) requirements. Make sure the filter will reduce possible energy exposure to below the Maximum Permissible Exposure (MPE). Check the Photopic Visible Light Transmittance (VLT) of the filter. VLT is the percentage of visible light transmitted through a filter, calculated against the spectral sensitivity of the eye to daylight. The higher the better. VLTs below 20% should be used in well-illuminated working environments.

Consider Absorptive or Interference filters-Absorptive filters may be polymer + dye based or glass, and function by absorbing laser energy. Interference filters employ thin layers of reflective material for protection. Hybrids combine both technologies.

Lightweight polymer filters offer varying VLTs and mid-level damage thresholds for UV, Visible and near IR, with lower damage thresholds for IR.

Polymer filters are cost effective, easy to wear and offer the highest impact resistance, while heavier glass filters can offer higher VLTs and higher damage thresholds at higher expense, and dielectrically coated and hybrids offer the highest VLTs, highest damage thresholds (in that some energy is not absorbed but reflected), at the highest cost.

STNR Series

STNR laser safety goggles have found applications in nearly every discipline that employs coherent or non-coherent light, including enhancement of fluorescence of bodily fluids and latent fingerprints for forensics; enhancement of chemiluminesence and fluorescence in medical, biological and even marine biological applications; dye enhancement in leak detection, patient protection in post-treatment pharmaceutical applications, UV protection in dental and industrial bonding/curing/whitening applications and more. Our standard goggles are listed below. Other wavelengths and styles are available on request.

STSD Series Laser Safety Goggles

STSDseries laser protective goggles are made of a sort of special plastics, which appends several well selected laser-absorbing dyes. They provide excellent filters to protect your eyes against laser beams used in scientific, industrial and medical applications. The protective characters and safety won’t change at different incident angles.

Remark:

• 1. OD³6 available for above items upon request.

• 2. V.L.T. means visible light transmission percentage.
