l Application: Beam Collimation, Focusing, Deflection

     Off-axis parabolic mirrors are surface mirrors whose reflective surface is a segment cut from a parent parabolic surface. They can be used to focus collimated beams or collimate point sources, with their off-axis design allowing the focal point to be separated from the optical path. Compared to lenses, off-axis parabolic mirrors do not produce spherical aberration, chromatic aberration, and introduce no phase delay or absorption loss, making them highly suitable for femtosecond pulse lasers. Since metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments, Tuniu metal-coated off-axis parabolic mirrors feature a protective silicon dioxide layer on the surface to isolate the metal coating from direct contact with air, preventing oxidation and preserving optical performance. Tuniu offers three types of metal-coated off-axis parabolic mirrors: gold-coated, silver-coated, and UV-enhanced aluminum-coated. The angle between the focused beam and the collimated beam is the off-axis angle. Tuniu provides off-axis parabolic mirrors with off-axis angles of 90° and 45°.

Attributes

Off-axis parabolic mirror, with protective gold coating, 800 nm-20.0 μm·

l Off-Axis Angle: 90°

     Tuniu offers gold-coated off-axis parabolic mirrors with working wavelengths ranging from 800 nm to 20 μm, which can focus collimated beams or collimate point sources without chromatic dispersion. Their off-axis design allows the focal point to be separated from the optical path. Additionally, gold-coated off-axis parabolic mirrors do not introduce phase delay or absorption loss, making them highly suitable for femtosecond pulse lasers. Since gold coatings are prone to oxidation, discoloration, or peeling in high-humidity environments, Tuniu gold-coated off-axis parabolic mirrors feature a silica protective layer on the surface to isolate the metal coating from direct contact with air, preventing oxidation and preserving optical performance. The base of Tuniu gold-coated off-axis parabolic mirrors includes three threaded mounting holes and two alignment holes arranged in a triangular pattern for convenient installation and use.

Off-axis parabolic mirror, with protective silver coating, 450 nm-20.0 μm

l Off-Axis Angle: 90°, 45°

     Tuniu offers silver-coated off-axis parabolic mirrors with working wavelengths ranging from 450 nm to 20 μm, which can focus collimated beams or collimate point sources without chromatic dispersion. Their off-axis design allows the focal point to be separated from the optical path. Additionally, silver-coated off-axis parabolic mirrors do not introduce phase delay or absorption loss, making them highly suitable for femtosecond pulse lasers. Since silver coatings are prone to oxidation, discoloration, or peeling in high-humidity environments, Tuniu silver-coated off-axis parabolic mirrors are coated with a layer of silicon dioxide protective film to isolate the silver coating from direct contact with air, preventing oxidation and preserving optical performance. The bottom of Tuniu silver-coated off-axis parabolic mirrors features three threaded mounting holes and two positioning holes arranged in a triangular pattern for convenient installation and use.

Off-axis parabolic mirror, with protective UV-enhanced aluminum coating, 250 nm-450 nm

l Off-Axis Angle: 90°

     Tuniu offers off-axis parabolic mirrors coated with UV-enhanced aluminum film, operating at wavelengths from 250 nm to 450 nm. These mirrors can focus collimated beams or collimate point sources without chromatic dispersion. The off-axis design allows the focal point to be separated from the optical path. Additionally, the UV-enhanced aluminum-coated off-axis parabolic mirrors do not introduce phase delay or absorption loss. The Tuniu UV-enhanced aluminum-coated off-axis parabolic mirrors feature three threaded mounting holes and two positioning holes arranged in a triangular pattern at the base, facilitating easy installation and use for customers.
