• Cuts Easily with Utility Knife
• Build Light-Tight Boxes

This heavy-duty construction board, which measures 5 mm thick, consists of a dense foam core sandwiched between two plastic-coated, moisture-resistant cardboard outer layers. The material cuts easily with a utility knife for construction of light-tight boxes. We recommend using our 2" wide black masking tape for corners and other joints to eliminate the passage of light through those areas.

We can cut this material into a custom size that fits your application. Please inquire with your local Tech Support office or email us at: TechSupport@thorlabs.com.
