Shelyak Spectroscope LISA near IR (54329)

The Shelyak LISA near IR spectroscope is a low-resolution, high-luminosity instrument designed for astronomical spectroscopy in the near infrared range (650–1000 nm). With an f/5 optical system and a resolution power of approximately R~600–1000, LISA is ideal for capturing faint objects and producing high-quality spectra. Its efficient optical design, including a focal reducer, ensures maximum light throughput, making it suitable for both research and advanced amateur use. The spectroscope is supplied with a custom-foamed carrying case for safe transport and storage.

This version of the LISA spectroscope is optimized for observations in the near infrared domain but is also available in a visible spectrum version for broader applications.
