LASER OPTICS

Lenses (1)

Plano-convex and Meniscus lenses are the most economical transmissive focusing elements available. They are ideally suited for laser heat treating, welding, cutting, and infrared radiation collection where spot size or image quality is not critical.
Protection Windows (1)

Laser system manufacturers install protective windows to protect the focusing lens from contamination. The protective window is positioned below the focusing lens, and is a barrier between the lens and the sheet.
External Optics (3)

Mirrors or total reflectors are used in laser cavities as rear reflectors and fold mirrors or externally as beam benders in beam delivery systems.
Internal Laser Optics (2)

Transmissive collimating optics are used in beam delivery systems to maintain beam collimation between the laser resonator and the focusing optics. Reflective collimators typically use copper total reflectors, while transmissive collimators typically use ZnSe lenses.
