Aspheric Lens
Xiaotong Optics has established an aspheric fabrication and testing center based on precision molding and thermoforming of aspheres and contact profilometer measurement, enabling stable production of high-quality aspheric lenses. Shapes include plano-convex, plano-concave, double-convex, double-concave, positive meniscus, and negative meniscus lenses. Materials include low-melting-point optical materials from Chengdu Guangming (CDGM) and Japan (HOYA). Various coating processes and coating systems are available for ultraviolet (UV), visible, and infrared (IR) wavelengths to meet diverse high-precision lens requirements. 1. Materials cover deep-ultraviolet to infrared bands; 2. Custom shapes and dimensions; 3. Diameter range: 3-50mm; 4. Clear aperture: 90% of the diameter; 5. Flatness: PV [source glyph: Chinese character meaning 'enter']/10@632.8nm; 6. Surface quality: 20/10 S/D; 7. Centration: 1'; 8. Standard or custom coatings; high laser damage threshold.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
