Product Description
  • Optical Material: Borofloat Glass, UVFS
  • Appearance Shape: Round and Rectangular
  • Application: Optical Path Deflection
  • Working Wavelength: 800 nm-20 μm
Metal-coated mirrors are highly suitable for deflecting light paths of broadband light sources, offering high reflectivity across a wide spectral range. LBTEK provides both protected and unprotected gold-coated flat mirrors, available in circular and rectangular shapes. The protected gold-coated mirrors feature a layer of silicon dioxide protective coating on the surface to isolate the metal film from direct external contact, preventing scratches that could affect optical performance. Unprotected gold-coated mirrors exhibit higher reflectivity than their protected counterparts but are more fragile and prone to surface scratches. All LBTEK mirrors undergo precision processing and strict quality control to ensure high-quality products at reasonable prices. For customized metal-coated mirrors, please contact LBTEK technical support.

LBTEK offers Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm gold-coated metal plane mirrors. Metal-coated mirrors are highly suitable for deflecting light paths of broadband light sources, as they exhibit high reflectivity across a wide spectral range. Since the gold coating itself is relatively fragile and prone to scratches, a silicon dioxide protective layer is applied on its surface to isolate the metal coating from direct external contact, preventing scratches that could affect optical performance.

LBTEK offers rectangular gold-coated mirrors, which are highly suitable for deflecting light paths of broadband light sources, featuring high reflectivity across a wide spectral range. Since the gold coating itself is relatively fragile and prone to scratches, a silicon dioxide protective layer is applied on its surface to isolate the metal coating from direct external contact, preventing damage to the gold coating that could affect optical performance.

LBTEK offers Ø25.4 mm unprotected gold-coated flat mirrors, which are suitable for deflecting light paths of broadband light sources and exhibit high reflectivity across a wide spectral range. Unlike aluminum or silver coatings, gold coatings are less prone to oxidation in air, allowing them to be used without protective layers. Unprotected gold-coated mirrors have higher reflectivity than protected ones, but they are also more fragile and susceptible to surface scratches. During use, care should be taken to avoid touching the gold-coated surface to prevent scratches that could affect performance.
