Aluminum (Al) Mirrors
Reflective Performance: The concave shapes and polishing procedure provide excellent reflective performance across the MWIR and LWIR wavelength ranges.
Monolithic Construction: Being constructed from monolithic aluminum blocks ensures robustness and durability in demanding environments.
Thermal Conductivity: High thermal conductivity of aluminum helps in dissipating heat efficiently, maintaining the stability of the mirror during operation.
Lightweight: Aluminum mirrors are lightweight compared to other materials, making them ideal for systems where weight is a concern.
Cost-Effective: The absence of additional reflective coatings reduces manufacturing costs, making these mirrors a cost-effective solution.
Applications: Thermal imaging systems, continuous zoom lenses, double FOV lenses, etc.
Aluminum (Al) Mirrors provided by Kingwin Optics are specialized optical components constructed from monolithic aluminum blocks. Unlike traditional mirrors, these Al mirrors do not require further deposition of reflective coatings; their reflective nature is achieved through precise concave shaping and meticulous polishing.
