Super Achromatic Waveplates
Crystock’s Super Achromatic Waveplate can provides extremely flat phase delay in a large Wavelength broadband. The broadband of Quarter Waveplates are 325-1100nm or 600-2700nm, the Half Waveplates are 310-1100nm or 600-2700nm. The Super Achromatic Waveplate of standard adopt Glued strutures.We can customize phase retardation and wavelength according to customer’s requirment.
Features：
•Provide flat phase retardation in a large spectral range.
Quarter wave plate,used for 325-1100nm or 600-2700nm
Half wave plate,used for 325-1100nm or 600-2700nm
•Glued strutures.
