High Transmittance Optical Glass
High-transmittance optical glass refers to glass whose transmittance in the blue-violet and visible light ranges is improved through process improvements over ordinary optical glass. Compared with ordinary-transmittance optical glass, high-transmittance optical glass can significantly improve the imaging quality of optical systems with long optical paths, and is suitable for high-end telescopes, digital projectors, etc. According to the degree of transmittance improvement, high-transmittance optical glass can be divided into high-transmittance and extra-high-transmittance optical glass, named by adding letters (GT, TT) after the grade. 'GT', the initials of 'gao tou' (high transmittance) in Chinese pinyin, indicates high-transmittance glass; 'TT', the initials of 'te' and 'tou' (extra and transmittance), indicates extra-high-transmittance glass. For example: H-ZF52GT, H-ZF52TT. Compared with ordinary-transmittance optical glass, high-transmittance and extra-high-transmittance optical glass only improve transmittance, with other properties unchanged.

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.
The 850 nm and 940 nm infrared narrow‑bandpass filters launched by Innovation Photoelectric are core optical components specially designed for day‑and‑night security cameras. They effectively eliminate image interference during visible‑light and infrared‑illumination switching, delivering stable round‑the‑clock monitoring performance.
Within cutting‑edge ultrafast photonics research, asynchronous optical sampling (ASOPS) and synchronous sampling serve as fundamental technologies for terahertz excitation detection, coherent Raman imaging and other time‑resolved spectroscopy experiments.
