Protective BoardAccessories

CKD LASER supplies kinds of laser protective board,the thickness is 5mm, according to DIN EN 12254: 2010 +AC: 2011 standard. They are made adding laser absorbent of specific wavelength to the substratematerial polymethyl methacrylate, which is suitable for a variety of lasere quipment. (It’s also called laser protective plate, laser protection glass,laser protective glass, laser protective window and so on).

Optical density: OD4+/OD6+/OD8+

Material: Polymethyl methacrylate (PMMA)

Functional material: rare metal complex

[Standard]: DIN EN 12254:2010 +AC: 2011

Thickness: 5mm

Standard size: 400*500mm. Can be customized.

Types and corresponding colors show:

How to choose right type, what kind is reliable?

(1)   Must cover the wavelengthof your laser machine / laser product / laser equipment.

(2)   The higher OD valuethe better.

(3)   The wider wavelength ranges the better. Because we need consider both direct and reflection,including diffuse reflection.

(4)   Consider the visibility, the higher OD value the lower visibility. If it’s safe enough for your laser machine,consider visibility is also important.

How to know the laser protective plate is real ornot?

Must pass professional optical test, meet safe standards, with declaration of conformity form.

The laser protective glass provided by our companyhas passed professional optical test, and the test tools used include but arenot limited to: laser power meter, laser, frequency multiplier, UV-visible infrared spectrophotometer, etc. It has also been tested by ESC GmbH in Germanyａnd conforms to the European Union DIN EN 12254:2010 +AC: 2011 standard.

To be easily understood, the following is the simple explain.

Notice: This is a VERY dangerous test, non-professionals are advised notto imitate, consequences shall be borne by the tester.

Shoot laser onSKL-A without extra lens, there appear a laser beam on SKL-A, the power of thisbeam is very powerful at this time. Then, shield a laser protective board betweenthe laser and SKL-A, the laser beam on SKL-A disappear. This is because thelaser is absorbed by the protective plate, which plays as a laser guarder / alaser defender.

The application of laser protective plate?

WHY IT IS SO IMPORTANT? You must know ALL:

Protect workers from REFLECTIVE exposure to CLASS 4LASERS (CLICK here for laser grades 1-4). Laser protective glass is usually installed on the laser protective window and enclosure, or placed in front ofthe light emitting area of the laser equipment. Laser protective glass has acertain light transmittance, which can not only observe the progress of thelaser equipment but also block a specific range of laser wavelength and reflectionlights generated from laser working, so as to effectively protect the human eyeａnd skin.

• Most of the danger of lasers comes from heat, but for certain wavelengths, there also exists dangerous photochemical effects.

• Using high-power lasers, even the reflected diffuselight can damage the eye.

• Focusing a lot of energy on a tiny spot in the retina, damagingphotoreceptor cells.

• Infrared lasers are particularly dangerous because they can't be seen, it doesn'ttrigger the blink reflex of eyes; Lasers in the 400-1400nm range penetrate theeyeball and heat the retina. The cornea and lens absorb energy, resulting incataracts or burns, and even the retina has no pain receptors after been broken!So, with exposed unprotected laser equipment,workers often don't even know they're injured until they notice a vision problem.

Laser protective glass is widely used in laserwelding, laser cutting, laser marking, laser guidance instrument, laser rangefinder and other laser optical systems. Suitable for laser industry, aluminumbattery manufacturing, robot manufacturing, auto manufacturing, lasermilitary exercises, laser surgery, medical, photocopier operation and otherfields.
