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.

eShel II complete system

50µm object fiber

fibre 195Object fiber for fiber-optic ladder spectroscopy systems, in particular the eShel spectroscope.

Connect the FIGU (Fiber Injection and Guiding Unit) to the eShel spectroscope.

Description

An optical fiber sends the starlight collected by the telescope to the spectroscope.

The optical fibers offered by Shelyak Instruments are optimized for use in astronomy, particularly with the eShel (or Whoppshel) system.

Specifications

Available in lengths of 5, 10 and 20 metres
Connectors: FC type (both ends)
Multimode Fiber
Numerical aperture : NA = 0,22
Core diameter: 50µm (for Object fibers)
5mm-diameter stainless steel cladding, for 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 consequence, this attenuation value (<0.5dB) is valuable whatever is the length (5, 10 or 20m). Since October 2017, the fibers optics “Objects” (50µm) are of type “High-OH”, offering a very good performance in the blue part of the spectrum. These fibers can be used from 380 to 800nm, or even above.
For “object” optical fibers, we have been using “High-OH” fibers since October 2017, which offer excellent performance in the blue and even near-UV range (usable from 380-400nm), right up to the infrared (800nm and more).
