SAFETY GLASSES
Serii CTL 2100
for your appropriate eye protection and safe operation with lasers
Working
with laser is entirely safe as long as you apply adequate protection
for your sight. Otherwise, laser beam impact can induce severe and
often irreversible damage to retina or cornea.

Otherwise, laser beam impact can induce severe and often irreversible
damage to retina or cornea. Eye injuries caused by incidental and
reflected laser beams are increasing due to the growing use of lasers
in industrial, scientific and medical applications. If you want to
secure sufficient eye protection, take advantage of our professional
anti-laser spectacles and goggles.
Basic usage features:
- We know that each laser user has a different needs, but we are trying
to crate products which will meet your special demands regarding
comfort, absolute safety and excellent visibility.
- Our anti-laser glasses give sufficient eye protection thanks to
special glass filters that attenuate from 100 times to over 10 billion
times the laser radiation of a given kind.
- Our protective eyewear afford efficient and reliable protection by
absorbing laser radiation while allowing harmless wavelenghts of light
to pass through. We make efforts to meet our customer individual needs
and offer both narrow band and broad spectrum glasses.
- We design narrow band eyewear for those who require specific
wavelength protection. Such glasses offer ideal balance between
effective attenuation of harmful radiation and, at the same time, allow
maximum transmission of light for the wearer to see clearly. Luminous
transmittance is high and visibility is good.
- Our broad spectrum filters are developed for protection against
lasers that emit light at two or more wavelengths. All multi-band
eyewear protects against the specific wavelength indicated as well as
any other laser radiation in the region covered by the filter as shown
in the presented diagrams.
- Colour glass plano lenses offer maximum protection and high luminous
transmittance. Filter media absorbs energy without creating hazardous
reflections. Not surface-coated absorbers cannot be scratched off thus
maintain light stability.
- Frames are perfectly ergonomic. The temples of spectacles have fine
adjustment of length for a comfortable matching to any face while
goggles can be worn over prescription glasses. Both types have air
vents preventing entry of light, yet admitting air to avoid fogging.
- Our clients have already recognised adventages of our production
based on high quality, reasonable prices and permanent innovations. Now
you can join them !!!
Selecting appropriate laser eye protection:
We offer a broad variety of protective glasses. The choice of the most suitable safety spectacles and goggles must be made in compilance with standard EN 166, EN 207 and EN 208. Since the use of unsuitable eyewear is one of the most frequent causes of eye injury. Please consider the following guide to select adequate glasses best suited to your particular laser application.
For a correct evaluation of optical hazards connected with exposure to laser beam, it is important to know some fundamental parameters defined in the norms describing safety standards for eye-protection against laser radiation.
Laser wavelength
Determine the laser wavelength used in your application. If you are using tunable systems or multiple lasers consider all applicable wavelengths to incorporate protection for all of them into one pair of glasses.
Laser mode
Check your laser output if it is continuous, pulsed or repetitively pulsed. In case of pulse mode aditionaly determine time duration to find out I, R or M type of laser.
Output parameters
In case of continuous wave laser check the maximum output power and beam diameter to calculate power density (in W/m2). For pulsed lasers determine maximum energy, beam diameter and frequency (if applicable) to calculate energy desity (in J/M2) or power density (for M type).
Stability to radiation
This is minimum power (or energy) density value that the protection filter of set class must comply with. Find the right stability to laser radiation parameter in the table (the adequate for full protection or alignment) higher and the closest possible to your calculated values. It determines spectral transmittance and optical density (scale number).
Spectral transmittance and optical density
Spectral transmittance is the ratio between the power (or energy) transmitted by the filter and the incident power. On the basis of this transmittance values, which vary from 10-1 to 10-10 (i.e. optical density from 1 to 10), ten levels of eye protection are defined by L1 to L10.
