The ENC45X60H-M optical enclosure provides reliable protection against dust and ambient light, making it ideal for sensitive optical setups. Measuring 450mm x 600mm x 300mm (L x W x H), this fully framed unit is built with our X2020 aluminum extrusion rail system and 3/16 in (5 mm) thick matte black hardboard panels, creating a lightweight yet rigid structure.Designed for maximum versatility, the bottom frame enables easy positioning and secure clamping anywhere on your optical table or breadboard. The removable top panel, secured with tabbed straps, allows for quick and convenient access to the interior. All laser-cut panels can be easily modified with a hobby knife, or we can precision cut to your specifications for a small additional fee. The enclosure arrives fully assembled, so it's ready to use right out of the box.
