Narrow Bandpass filters
Product Overview: The spectral bandwidth of the optical filter is relatively small compared to the central wavelength (for example, <2%), allowing only a very narrow spectral transmission of specific target bands. Filters that cut off on both sides of the passband are called narrowband filters.
General technical specifications of narrowband optical filters: center wavelength (CWL), full width at half maximum (FWHM), peak transmittance (T%), blocking depth (OD), blocking range, and background noise suppression level (OD); different application scenarios have significant differences in requirements for the spectral performance, tolerance, environmental adaptability, and structural form of the filters.
The company has an experienced optical coating engineering team that can select suitable coating materials, coating processes, film system designs, and film thickness monitoring methods to provide customized solutions for customers based on comprehensive factors such as the operating wavelength band, spectral bandwidth, incident angle, background suppression, and application scenarios of narrowband filters. The company can complete the entire process from sample development to mass production. Free technical consultation and assessments of product performance and mass production feasibility are provided. Applications include: biomedical, spectral analysis, security monitoring, LiDAR, remote sensing, optical fiber communication, and other scenarios. The center wavelength and specifications can be customized according to customer requirements.
