At Z-Optics, we offer premium-quality bandpass filters with a Full Width at Half Maximum (FWHM) of 50 to 60 nm, engineered to provide excellent spectral selection in a wider bandwidth range. These filters deliver reliable wavelength isolation with high transmission and effective out-of-band blocking, making them ideal for applications where broader spectral control is essential.

Key Features

  • Wide Bandwidth Control: FWHM of 50–60 nm provides effective isolation of target spectral regions while allowing a broader range of wavelengths to pass through for diverse applications.
  • High Transmission Efficiency: Achieves over 85% peak transmission ensuring optimal light throughput with minimal losses.
  • Strong Out-of-Band Blocking: OD3 to OD4 blocking outside the passband reduces unwanted stray light for enhanced signal clarity.
  • Durable Optical Coatings: Designed for high durability and environmental stability, suitable for both laboratory and field use.
  • Customizable Centre Wavelength: Available across UV, visible, and near-infrared regions, with ±1 nm wavelength tolerance tailored to your system requirements.
  • Compact and Robust Design: Precision mounted filters compatible with standard optical holders and instruments.

Applications

  • Fluorescence Imaging and Spectroscopy: Enables selection of excitation or emission bands with broader spectral tolerance.
  • Multispectral and Hyperspectral Imaging: Provides controlled spectral bands for imaging applications requiring medium bandwidth filters.
  • Environmental and Biological Sensing: Enhances detection of analytes across wider spectral signatures.
  • Laser Systems & Optical Communications: Ideal for wavelength selection and noise reduction in systems requiring mid-range FWHM filtering.
  • Industrial Process Monitoring: Facilitates spectral isolation of emissions or reflections in process control.
