The MCWlaser laser glasses listing, bullet by bullet

Five bullets: a 190–540 nm range at OD7+, 50 % visible light transmission and a 190–540 nm DIRM LB7 marking to EN 207:2017, with typical wavelengths from 275 to 532 nm; uses from ultraviolet lamps and violet, blue and green diode lasers to engraving, cutting and cosmetic treatments; an absorbing lens material, with the claim that scratches do not reduce the filter; a lightweight, impact-resistant PC frame with side and brow protection that fits over prescription glasses; and an offer of advice from MCWlaser’s engineers.

MCWlaser quotes its marking

190–540 nm DIRM LB7. An EN 207 marking names the wavelength range, the laser modes and the protection level in one string, and it is printed on the eyewear. MCWlaser puts the whole string on the page, which lets a buyer compare it with their laser’s published wavelength and mode before ordering.

MCWlaser and visible light

A 50 % visible light transmission means the view through the lenses is noticeably darker than without them. It is the only listing of the three glasses on this site to give that figure. The product photograph shows the marking printed on the lens, alongside a zip case and a soft pouch that the bullets do not mention.

Availability

At the last look-up, the German, French, Italian and Spanish Amazon stores were asking roughly 45 €.

It is sold in the British Amazon store as well, in its own currency, which the euro figures above leave out on purpose.

The American Amazon catalogue lists the product, yet no seller was offering it.

Every figure here is Keepa’s reading on the date this page was last updated. Stock and prices can change at any time.
