Herschel Lunt Calcium-K prism for Lunt LS130MT

Herschel Lunt Calcium-K Prism: Solar observation in the Calcium-K line

The Herschel Lunt Calcium-K prism is a high-precision accessory designed specifically for the LS130MT modular telescope. This tool enables observation of the Sun in the Calcium-K (Ca-K) line, centered on the 393.4 nm wavelength, while offering maximum safety and outstanding image quality. Highlighting the intense magnetic zones and dynamic structures of the solar chromosphere, this prism is ideal for astrophotographers and enthusiasts wishing to explore a unique facet of the Sun.

Scientific operation: The Calcium-K line and the Herschel prism

The Calcium-K line is produced by the ionization of calcium in the solar chromosphere, revealing details such as supergranulation cells, active regions and sunspots. Herschel's prism deflects around 95 % of sunlight and heat into an integrated light trap, while the remaining 5 %, attenuated by internal filters, is transmitted to the eyepiece or camera. This process guarantees safe observation while maintaining superior sharpness and contrast.
