Aspheres Aspherical Optics - Optical Components

Aspheres – precision aspherical optics manufactured by ZYGO''s Optics business segment – can be manufactured in sizes up to 500 mm, with tolerances better than λ/5000 RMS @ 633 nm.. In the digital age, aspheres are growing in popularity in modern optical lens designs. Aspheric surfaces can now be found in most IR designs, and are increasingly prevalent in the visible and DUV spectrum for a

Optical Properties of Silicon | PVEduion

The optical properties of silicon measure at 300K 1. While a wide range of wavelengths is given here, silicon solar cells typical only operate from 400 to 1100 nm. There is a more up to date set of data in Green 2008 2. It is available in tabulated form from pvlighthouse as text and in graphical format.

High-Rigidity Ceramics (Silicon-Infiltrated Silicon

Our high-rigidity ceramics consist of compound materials based on Silicopn Carbide with additional Silicon infiltration. Our reaction bonding process makes it possible to mold complex hollow shapes. SiSiC''s low outgassing also makes it ideal for use in a vacuum environment.

Silicon Vacancy | Scientific.Net

Relying on this identifiion, here we carry out high precision ab initio simulations on negatively charged silicon vacancies in 4H and 6H-SiC and calculate the most important magneto-optical data, such as the zero-phonon photoluminescence energies, the zero-field-splitting, and the hyperfine tensors for the nearest and farther nuclear spins.

Experimental research on silicon carbide photoconductive

Silicon carbide photoconductive semiconductor switches with the good performance of breakdown voltage above 10 kV and ∼16‐Ω minimum on‐resistance are fabried and tested. A good electrical pulse output is obtained when the switch is triggered by optical pulses. The output performances with different bias voltages are discussed, and the
