土耳其采购需求：硫系玻璃、硫系材料的应用、硫系材料的含义、冷却红外、红外、红外相机

I'm reaching out for your expertise in manufacturing gimbals, specifically for a project involving an IR camera. I need a glass component measuring 120 mm in diameter and between 2-3 mm thick. The critical requirement is high thermal conductivity and IR transmissivity to ensure optimal performance. Could you provide suggestions for materials that balance cost and performance effectively? Initially, I plan to acquire 1-2 prototypes, but there's potential for larger orders in the future, reaching up to 1000 units. Your guidance in selecting the most economical option that meets these specifications would be greatly appreciated. Looking forward to your feedback and a quote.
