Specifications
Ultraopto’s 10nm Bandpass Filter is a high-precision narrowband optical filter engineered with advanced dielectric coating technology, featuring a fixed 10nm full-width at half-maximum (FWHM) passband for precise spectral isolation, serving as a core component in near-infrared (NIR) spectroscopy, optical measurement, laser system alignment and industrial spectral detection systems. Crafted from premium optical-grade glass and fused silica substrates, our product is available for center wavelengths across the UV, visible and NIR spectral ranges (standard model CWL=1000nm for NIR), with an average peak transmittance of ≥85% at the design center wavelength and steep spectral edge transitions, ensuring precise spectral isolation and minimal spectral leakage, and the out-of-band rejection region features an optical density of ≥3, effectively blocking unwanted light and maximizing the signal-to-noise ratio for narrowband spectral detection and measurement systems. Manufactured with strict precision optical processing and coating technology, the filter ensures consistent 10nm FWHM passband width across the entire clear aperture, with no passband deformation or width variation, providing stable and reliable narrowband spectral performance for quantitative optical analysis applications.
We offer the 10nm Bandpass Filter in both unmounted and mounted configurations to meet diverse optical system integration needs, with unmounted filters featuring a thin substrate design (0.5mm, 1.1mm, 2.0mm thickness) and mounted filters available in smooth, metric, C-mount and SM thread mounts for easy installation and protection of the optical surface, with standard mounted diameters of 12.5mm and 25mm, and fully customizable diameters and mounting thicknesses (3.5mm, 6mm, 7.62mm, etc.). The filter achieves a clear aperture of over 90% for both unmounted and mounted models, ensuring efficient light transmission and minimal light loss, and the durable dielectric coatings exhibit excellent scratch resistance and environmental stability, withstanding temperature changes, humidity and frequent cleaning, ensuring long-term stable operation in both laboratory precision testing and industrial field conditions. Our 10nm Bandpass Filter also features low chromatic aberration and uniform spectral response across the entire clear aperture, avoiding signal distortion and ensuring accurate and repeatable spectral measurement results.
Ultraopto’s 10nm Bandpass Filter is widely applied in a broad range of professional narrowband optical fields, including near-infrared (NIR) spectroscopy for conducting material composition and quality analysis by detecting narrowband NIR spectral signals, and optical measurement systems for precise wavelength calibration and light intensity measurement, ensuring high accuracy and repeatability of measurement results. In laser systems, it is used for laser line alignment, laser beam cleanup and narrowband laser excitation, ensuring pure laser beam output and accurate laser system operation, and in industrial spectral detection for quality control of industrial products such as pharmaceuticals, food and chemicals by detecting specific narrowband spectral characteristics of materials. It also serves as a core component in portable spectral analysis equipment for on-site field detection of environmental pollutants and industrial contaminants, in biomedical research for narrowband fluorescence detection of biological samples, and in machine vision systems for narrowband spectral imaging and surface defect detection of industrial products. Additionally, the filter is used in optical metrology instruments for high-precision wavelength and spectral response calibration, as well as in laboratory optical experiment platforms for narrowband spectral analysis and optical research.
As a leading manufacturer of precision narrowband bandpass optical filters, Ultraopto offers fully customized 10nm Bandpass Filter solutions to meet your unique narrowband spectral application requirements. Our professional R&D and engineering team can tailor the center wavelength across the UV, visible and NIR spectral ranges, with ultra-strict tolerance control for the 10nm FWHM passband width and center wavelength to ensure precise spectral isolation. We also provide custom optical density levels for the out-of-band rejection region (up to OD6), custom substrate materials (optical-grade glass, fused silica) for different spectral ranges and environmental requirements, and fully customized mounting configurations (unmounted, smooth mount, metric mount, C-mount, SM thread mount) and dimensions to fit your specific optical system integration needs.
All custom 10nm Bandpass Filter orders undergo multi-stage strict narrowband optical performance testing and quality inspection, including transmittance measurement, FWHM verification, center wavelength testing and mounting compatibility testing, with a detailed quality inspection report provided to ensure the final product fully complies with your design specifications and application needs.
