Yutai's Equilateral Dispersing Prisms disperse a light into its different colors. Each colors in the light incident at an oblique angle to the first face emerges as a spectrum from the opposite face. They have the best combination of wide dispersion and low reflection losses because of their roof angle of 60 degrees. They are often used as optical component for dispersing the spectrum. Chngchun Yutai optics supply both BK7 and fused silica for a selection of wavelength range from UV to near IR.
