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, LBTEK's 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. LBTEK 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. LBTEK provides off-axis parabolic mirrors with off-axis angles of 90° and 45°. For other customized specifications, please contact LBTEK Technical Support.

Off-axis parabolic mirror, with protective gold coating, 800 nm-20.0 μm
- Optical Material: Aluminum Substrate
- Working Wavelength: 800 nm-20.0 μm
- Application: Beam Collimation, Focusing, Deflection
- Off-Axis Angle: 90°
LBTEK 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, LBTEK's 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 LBTEK's 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.
The off-axis parabolic mirror is mounted in the mirror holder via an adapter.

- Off-Axis Angle: 90°, 45°
LBTEK 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, LBTEK's 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 LBTEK's 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.
