We can provide small-sized lenses for infrared detectors, as well as medium-sized lenses for analysis and imaging. At the same time, large lenses for public safety and aerial photography have great advantages. We are committed to double-sided grinding and polishing, CNC processing and coating processing, mainly involving infrared lenses, infrared windows, infrared lenses, infrared aspheric lenses, including zinc sulfide series, zinc selenide series, chalcogenide glass (IRG206/204/201/207/203), germanium series, silicon series, and aviation aluminum series.
