A pair of wedge prisms (one with strong chromatic dispersion (WP1, N-SF11 glass, refractive index n = 1.791 at 550 nm and another with weak chromatic dispersion (WP2, N-LAF21 glass, refractive index n = 1.792 at 550 nm)) designed and manufactured by Shanghai Optics were utilized in a monolithic dual-wedge prism-based spectroscopic single-molecule localization microscopy system.

(a) Schematic of the 3D sSMLM system with the DWP unit; (b) Zemax design of the DWP unit optical assembly. (c) Picture of the DWP unit optical assembly, which consists of a customized DWP pair and a commercially available lateral beam splitter. BS: cube beam splitter; RP: right-angle prism; WP: wedge prism; AR: anti-reflection coating; OL: objective lens; BPF: band-pass filter; DF: dichroic filter; LPF: long-pass filter; TL: tube lens; M: mirror; DWP unit: dual-wedge prism unit; IP: image plane; C: camera plane.
