Key Takeaways: Laser-Induced Damage Threshold (LIDT) defines the laser energy or power at which materials sustain permanent damage. It varies with laser type—pulsed or continuous—and is influenced by factors like pulse duration, wavelength, material defects, and thermal properties. Pulsed lasers often cause non-thermal damage via ionization, while CW lasers primarily induce thermal effects. Testing methods […]
Wide Field Space Imaging Project Overview Meeting the growing demand for large-area Earth observation requires optical systems that combine wide field of view, high optical performance, and compact design. One such solution is a space camera optical system based on an off-axis four-mirror freeform design, achieving a 70° ultra-wide field of view from a 640 […]
Key Takeaways Satellite telescope coatings must support wide spectral ranges (UV to LWIR) while enduring radiation, AO exposure, and thermal cycles. AR coatings for lenses and windows require high transmittance, environmental resistance, and minimal outgassing. Gold and silver reflective coatings are essential for high-efficiency IR mirrors in thermal imaging telescopes. AO-resistant layers like ALD-deposited Al₂O₃ […]
Key Takeaways Objective lenses are essential in quantum computing for precise beam focusing, efficient fluorescence collection, and high-resolution qubit imaging. High numerical aperture boosts addressability and readout fidelity, while optimized working distance enables operation through vacuum or cryogenic interfaces. Wavelength-specific coatings, aberration correction, and window compensation preserve signal integrity. Vacuum and cryogenic compatibility, along with […]
Key Takeaways Design optimizations enhanced telescope manufacturability and performance. Replacing the optical tube with carbon fiber reduced weight and improved thermal stability. A redesigned secondary mirror mount with locating pins and adhesive injection holes ensured precise, long-term alignment. Adding shims and positioning pins between the primary mirror and tube enabled fine-tuned alignment and post-assembly stability. […]
