Wear the timeless red glow of the helium neon laser.
You can call it HeNe for short, because its 632.8 nanometer wavelength is as familiar as they come. It’s not a powerful laser but it emits red light and does not quit. Got an old laser from the 1980s that still works? It’s probably a HeNe. Every lab should have one!
Find the "unisex fit" too boxy? This t-shirt is for you! Perfect for lab wear, or dress it up with a jacket to make all your colleagues at the conference incredibly jealous.
