Achromatic half or quater waveplates with a retardation tolerance of λ/100. Extremely broad wavelength range with only one optic. Our standard achromatic waveplates are cemented. These are not suitable for higher power applications. For higher power applications, please contact us. We can often supply air-spaced waveplates, depending on the wavelength and retardance required. Specifications: | Material: | Birefringent Crystals | | Wavefront distortion: | λ /4 @ 632.8nm | | Retardation Tolerance: | λ /100 | | Parallelism: | <10 arc second (for cemented type) | | Standard Wave: | quater wave (λ/4), half wave (λ/2) | | Coating: | uncoated for standard, AR coating available | | Working Wavelength: | 450-650nm, 550-750nm, 650-1100nm, 900-2100nm |
Please specify your required diameters or with or without mount in your order.
