Equilateral Prism SF10 30mm
Description
Equilateral Prisms are used routinely as dispersing elements where spectral separation is required. They provide better brightness (lower stray light) than diffraction gratings. They also have greater power handling capabilities and avoid possible confusion when trying to interpret overlapping spectral orders. It must be remembered that dispersion is non-linear with wavelength and that surface reflection losses may affect throughput. Ealing offers Equilateral Prisms in three materials designed to suit a wide variety of dispersion, wavelength, and surface reflection requirements. In general, a higher refractive index material produces greater angular separation.

Frequently Asked Questions
Equilateral Prisms are used as dispersing elements where spectral separation is required.
Equilateral Prisms provide better brightness (lower stray light) than diffraction gratings. They also have greater power handling capabilities and avoid possible confusion when trying to interpret overlapping spectral orders.
Ealing offers Equilateral Prisms in three materials: BK7, SF10, and F2.
In general, a higher refractive index material produces greater angular separation.
BK7 has a wavelength range of 330-2100 nm, SF10 has a range of 400-2400 nm, and F2 has a range of 350-2200 nm.
