The achromatic wave plate is composed of two different materials of birefringent crystals. Due to the different dispersion of the two materials, it can achieve relatively uniform phase delay over a wide wavelength range. The achromatic wave plate is also less sensitive to temperature.
• Ultra wide wavelength bandwidth
• Support customer customization
• Gluing and air gap options available
