The Hobby-Eberly Telescope (HET)(+), located in West Texas at the McDonald Observatory, operates with a fixed segmented primary (M1) and has a tracker, which moves the prime-focus corrector and instrument package to track the sidereal and non-siderea

Modern large telescopes such as TAO, LSST, TMT and EELT require 0.9m-4m monolithic convex secondary mirrors. The fabrication and testing of these large convex secondary mirrors of astronomical telescopes is getting challenging as the aperture of the

The growing field of high-order aspheric and freeform optical fabrication has inspired the creation of optical surfaces and systems which are difficult to align. Advances in optical alignment technology are critical to fabricating and integrating asp

We study the dynamic response of a mechanical quartz tuning fork in the temperature range from 9 K to 300 K. Since the quality factor Q of the resonance strongly depends on temperature, we implement a procedure to control the quality factor of the re

Conference on Characterization and Radiometric Calibration for Remote Sensing (CALCON)
The Wide Field Instrument (WFI) on NASA’s Roman Space Telescope (RST) has an on-board calibrator called the simplified Relative Calibration System (sRCS). The sRCS is designed to project flat-field calibration light onto the WFI focal plane in two

The Operational Land Imager 2 (OLI-2) has undergone absolute spectral radiance calibration at Ball Aerospace. A 40” integrating sphere source (DSS) is used as the NIST-traceable artifact in the OLI-2 ground calibration. The required 2.5% accuracy (
