LBTEK high-quality bandpass filters are constructed using UV-grade fused silica substrates and advanced ion beam-assisted hard coating technology. Through precise thin-film design, these filters ensure complete transmission of optical signals within the center wavelength and bandwidth. Currently, the high-quality bandpass filters offer 24 center wavelengths within the range of 355-1064 nm, two sizes (Ø12.5 mm, Ø25 mm), and two bandwidth options (FWHM=10 nm, 50 nm). These products feature high transmittance (>85%, >90%) and high blocking depth (ODabs >5) within the operating wavelength range of 200-1200 nm. They are widely suitable for various application scenarios such as laser processing monitoring, fluorescence imaging, spectral analysis, and optical inspection, meeting diverse needs in optical experiments and industrial applications. Additionally, LBTEK offers customization services for wavelength, bandwidth, and size. For custom orders, please contact technical support.

LBTEK High-Quality Bandpass Filters (FWHM=10 nm), covering multiple center wavelength options within the 355-1064 nm band (T＞85%@center wavelength), available in two standard sizes: Ø12.5 mm and Ø25 mm, to meet diverse application needs. The filters are pre-installed in black anodized aluminum rings, with the arrow on the housing indicating the direction of incident light for easy installation and use. The filter's dielectric coating thickness is designed for collimated light at normal incidence. If the light is not collimated or does not strike the filter surface at normal incidence, the designed center wavelength will shift towards shorter wavelengths, and the bandpass transmittance will change. This filter is perfectly compatible with the entire range of LBTEK standard lens tubes, fixed lens mounts, and various coaxial mounting plates, allowing customers to choose the optimal installation method based on their specific application scenarios.
