Zinc Selenide is a chemically vapor deposited material commonly used in thermal imaging,FLIR,and medical systems.It has wide usage in high power CO2 laser systems because of its low absorption coefficient and high resistance to thermal shock.Zinc Selenide is a relatively soft material that scratches easily and it is not recommended for use in harsh environments(Knoop Hardness 120).Great care must be taken during handling,mounting,and cleaning.Apply uniform pressure when handling,wear Latex finger cots or gloves to prevent contamination and do not use tweezers or other tools.
Zinc Selenide Infrared(IR) Focusing-lenses are designed to provide maximum coupling efficiency between the output from an IR source and a single-mode or multi-mode transmitting fiber optic.The aspheric design provides a focal spot smaller than the fiber core diameter,allowing for precision alignment without negatively impacting transmission between the objective and fiber.Zinc Selenide Infrared(IR) Focusing Objectives are available with multiple anti-reflection(AR) coating 10.6μm,and are ideal for a range of fiber coupling and IR focusing applications.
