Broadband Coated Flat Dielectric Mirror Description
Coligh’s broadband dielectric mirrors support wideband reflection from the ultraviolet (250 nm) to the near-infrared (2000 nm), making them ideal for multispectral systems. This extensive wavelength coverage ensures that the mirror operates stably in the UV, visible, and near-infrared regions.
- We utilize hard oxide and fluoride coating materials that are capable of withstanding extreme environments. This not only extends the service life of the mirror but also guarantees durability and resistance to laser-induced damage even under harsh conditions.
- Through precise film system design and meticulous layer engineering, constructive interference is achieved to realize an average reflectance greater than 99%. This high reflectivity enhances the efficiency of the optical system and reduces energy loss, making the mirror well-suited for high-power lasers and precision optical instruments.
- Furthermore, we offer coating capabilities for large-sized dielectric mirrors, with customizable dimensions up to 1000 mm. Customers can also choose different substrate materials such as K9, BK7, or fused silica according to their specific requirements.
