Achromatic Wave Plates

Thorlabs offers both quarter- and half-wave achromatic plates. Each is housed in a Ø1" mount, an SM1-compatible mount, or within a FiberBench-compatible module. Depending on the item chosen, broadband performance is available over a wavelength range that falls between 260 nm and 2.7 µm, with our superachromatic wave plates offering the largest wavelength range within a single design (310 - 1100 nm or 600 - 2700 nm).
