NIR Achromatic Waveplate

We pushed out Diameter 25.4mm λ/2 and λ/4 achromatic waveplate ,it is composed of quartz crystal and magnesium fluoride (MgF2),which makes it is not sensitive to the wavelength ，the nearly flat spectral response can be obtained in the working wavelength range. There are 400-700nm、700-1100nm、1100-1650nm wavelength range for your choice according to your application , at the same time, we can also customize the achromatic waveplate for you based on your requirement
