What is typical application for 1010nm bandpass filter?
A 1010 nm bandpass filter is a precision optical component that only allows light within a narrow band centered at 1010nm in the near-infrared range to pass through, while blocking all ultraviolet, visible light and other out-of-band wavelengths. Typical applications for 1010nm bandpass filter is very broad, include near-infrared laser systems, spectral analysis and optical sensing. It also applies to industrial photoelectric detection, laser measurement and scientific research instruments, effectively filtering unwanted light interference to improve signal purity and detection accuracy.
What is key parameter when choose for right bandpass filter?
When selecting a bandpass filters, the center wavelength (CWL) will be one of key parameter to be designated, it refer to the wavelength at which the filter achieves maximum transmission. Secondly, Peak and Average Transmittance, typically ≥80–95%, higher transmittance might need Anti-reflective(AR) coating. Third, full width at half maximum (FWHM). Forth, Blocking Range & Depth. Fifth, substrate material, e.g., BK7, B270, fused silica, colored glass. Sixth, surface quality, e.g., 60/40, 40/20. Seventh, Size & Shape, etc.
Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical technology that apply depositing nanomaterials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which coating layer is firm and has good tightness, and small bandwidth drift. Liyuan optoelectronics have been focus on optical coating for more than 17 years and offer one-stop optical filters solution including Narrow Bandpass Filters, IR cut-off Filters, Longpass & Short Filters, Notch Filters, ND filters, Star filters and Optical sapphire block.
