ColorLock™ Filter Stacks Enable Better Wide-Angle Imaging
New glass filters overcome considerable design challenges to transmit wide-angle incident light without shifting wavelengths, offering an innovative solution for a variety of applications in which the high transmission afforded by dielectric filters is less important than the consistency of the wavelengths of light coming in from wider incident angles. Parents lament that their children are not getting enough exercise because they spend too much time playing video games. The edge of this
