MidOpt AC380 Acrylic A/R Protective Window
AC380 is an abrasion, scratch, breakage and solvent resistant acrylic protection window made to withstand harsh environments that is also half the weight of glass windows.
Compared to untreated acrylic, the vacuum-sputtered coatings applied to these windows are 50 times more scratch resistant and impervious to all types of fuels and chemicals, especially chlorinated solvents, acetone and MEK.
AC380 material blocks almost all UV light while averaging greater than 98% transmission in the 450-700nm visible spectrum. This protection window is a highly effective yet economical solution for covering camera enclosures and on-axis lighting. Available from stock in 2mm and 3mm thicknesses, custom sizes and shapes can be quickly laser cut in house. This material is often used in FDA/EFSA applications.
*F0r 1mm thickness or standard 25.4™ C-Mount option, please see AC370. For filters thicker than 1mm, we offer an alternative mounting C-mount solution that has an overall thickness of 5.5mm. This mount can accommodate filters up to 3.5mm thick. To view this alternative C-Mount option, click here.
