1m F/8 Ritchey Chrétien with dual Nasmyth Foci, Cape Town (South Africa)

Another large telescope for the South African Astronomical Observatory (SAAO). An 1m F/8 Alt-Az mounted Ritchey Chrétien for robotic use. It has dual Nasmyth Foci. The main telescopes used for research are located at the SAAO observing station (32°22.795’S 20°48,657’E) near Sutherland in the Northern Cape, a 4-hour drive from Cape Town.

Calibration optical fiber 200µm

pf0019 fibre calibration 200µm l10m t210x117 178 200µm calibration fiber for fiber-fed Echelle spectroscopy systems, in particular for the eShel spectroscope. or the Whoppshel.
This fiber conducts light from the calibration module to the FIGU.
Contact us if you need specific lengths.

Description

The optical fibers offered by Shelyak Instruments are optimized for use in astronomy, particularly with the eShel and Whoppshel systems.

Specifications

Length: 10 or 20 meters, stainless steel protection.
Connectors : FC-FC
Multimode Fiber
Numerical aperture : NA = 0,22
Core diameter: 200µm for calibration fibers
A 5mm-diameter stainless steel sheath provides optimum protection… even at night (no risk of breakage if you step on the optical fiber).

Note: losses mainly occur in the junctions, at connector level. The transmission of the fiber itself, up to some dozens of meters, is close to 100%. As a result, the attenuation (<0.5dB) is valid regardless of the optical fiber length (5, 10 or 20m).
