Optical design of a direct fibre-fed MO-IFS for the NLOT
Nitish Singh, S. Sriram, Totan Chand +3
The initial optical design and performance analysis of a dual-channel fibre-fed Multi-Object Integral Field spectrograph (Mo-IFS) being designed for a future National Large Optical…
Design and Development of a Lab Prototype of a Fiber-Based Integral Field Spectrograph
Nitish Singh, S Sriram, Jurgen Schmoll +1
Integral Field Spectroscopy provides simultaneous spatial and spectral information, making it a powerful technique for studying both point like and extended astronomical sources. A…
Design of a three-lens wide field corrector with aspherical surfaces for the 2.34-m VBT
Nitish Singh, S. Sriram, Bharat Kumar Yerra
We are developing a compact three-element Wide Field Corrector (WFC) with spherical and aspherical lenses for the 2.34 m Vainu Bappu Telescope (VBT) to enhance its field coverage f…
Design and Fabrication of a lightweight three-lens corrector system for the 2.34-m Vainu Bappu Telescope
Nitish Singh, S. Sriram, Ramya Sethuram +8
The Vainu Bappu Telescope (VBT) is a 2.34-m reflector, primarily supported on-axis field of view, offering high-resolution and low-to-medium resolution spectroscopic observations i…
