    Made of calcium fluoride, these windows let you safely take the temperature of electronics without opening your enclosure. Unlike glass and plastic windows, these windows let short-, mid-, and long-wave infrared light pass, so you can use infrared thermometers or cameras for detailed thermal imaging. Since you're not opening the enclosure, they help you comply with NFPA 70E and reduce the risk of arc flash injury. They are compact enough to fit a variety of panels. Install them using standard-sized knockout punches.
    316 Stainless Steel Frame—316 stainless steel frames resist corrosion better than aluminum frames.
