The MidOpt AC400-48 is a 3mm-thick abrasion-, scratch-, breakage-, and solvent-resistant acrylic protective window designed to withstand harsh environments. It is half the weight of comparable glass windows and also features an external oleophobic coating that reduces fingerprint smudging. The vacuum-sputtered coatings on both surfaces are 50 times more scratch-resistant than untreated acrylic, far more durable than standard “dip” coatings, and are impervious to all types of solvents, fuels, and other chemicals, including acetone, methylene chloride, and MEK.This material blocks almost all UV light while averaging greater than 98% transmission over the 450-700nm visible spectrum. This protective acrylic window is a highly effective yet economical solution for covering screens, camera enclosures, and on-axis lighting modules. It is often recommended for FDA/EFSA applications where thickness is a concern and glass use is not permitted. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
