Dielectric Mirrors and Metallic Mirrors Applications

Narrowband dielectric mirrors and broadband dielectric mirrors are critical components in high-power laser systems, enabling precise beam control. These wavelength-specific mirrors are widely used in industries such as laser processing and medical lasers.

Metallic mirrors also known as wideband reflectors, with their broad-spectrum reflectivity, are suitable for applications ranging from ultraviolet to infrared wavelengths. They are commonly used in scientific instrument and education for broadband reflection systems.

In industrial inspection and equipment, both dielectric and metallic mirrors are employed in processing equipment and industrial vision and thermal imaging systems, ensuring reliable optical performance.

In consumer electronics, such as AR and VR devices, mirrors are used for reflection and beam splitting, enabling precise optical path guidance and control.
FAQs
We primarily provide flat optical mirrors, which can be processed into standard shapes such as square and round, as well as customized special shapes to flexibly meet diverse application requirements.
We offer mirrors made from optical glass or metal substrates, including dielectric mirrors and metallic mirrors. Material and coating options can be selected based on the specific application needs.
Typically, we produce optical mirrors with sizes up to 500mm. However, we have experience manufacturing mirrors of around 700mm. The maximum size depends on technical parameters and testing requirements. If you have larger size requirements, feel free to discuss them with us.
We can typically achieve a surface accuracy of λ/20@633nm. However, this depends on factors such as the mirror size and coating parameters. Under specific conditions, we can produce optical mirrors with even higher precision.
Our mirrors can support incidence angles ranging from 0° to 80°. The specific range depends on the coating and size requirements. Please contact us to discuss your detailed needs.
