Design, integration, and commissioning of the BIFROST all-in-one 4-telescope beam combiner for 1.0–1.8μm spectro-interferometry
Sorabh Chhabra, Stefan Kraus, Daniel Lancaster, John Monnier et autres
The ASGARD/BIFROST instrument provides spectro-interferometric capability for the VLTI across the 1.0–1.8μm wavelength range. Central to this system is the All-in-One (AIO) 4-telescope beam combiner, which integrates beam routing, spatial filtering, and spectrograph injection within a compact optomechanical assembly. We present the …
