Hello, i want to build an enclosure for my 445nm CNC engraver. I have a piece of 3mm acrylic (fluorescent orange) i dont have a 445nm meter but seems to be efective for blocking the 445nm, i tested also a piece of kaptom tape and seems to be also efective (less than acrylic), but if i cover the acrylic sheet with kapton seems to bee very efective. Is anyone able to test the kapton tape properties for blocking the 445nm?
