254nm UV Bandpass Filter with 10nm FWHM

This high-performance bandpass filter is designed to isolate a narrow spectral band centered at 254 nanometers (nm) with a Full Width at Half Maximum (FWHM) of 10nm. It effectively transmits light within the range of 249nm to 259nm, while significantly attenuating wavelengths outside this range.

Coligh offers 254nm bandpass filter with a 10nm Full Width at Half Maximum (FWHM) offers superior performance for applications requiring precise wavelength isolation. Its key advantages include:

Key features:

• Narrow Bandwidth Precision: With a 10nm FWHM, this filter ensures sharp, accurate filtering, enhancing the resolution of spectral measurements.
• High Transmission Efficiency: Designed to maximize transmission at the 254nm center wavelength, ensuring optimal light intensity and signal clarity within the desired range.
• Exceptional Out-of-Band Rejection: Provides excellent attenuation of wavelengths outside the 249nm to 259nm range, reducing background noise and improving the contrast in your applications.
• Reliable Performance: Engineered for stability and consistency, making it ideal for demanding environments in UV spectroscopy, fluorescence microscopy, and other high-precision optical tasks.
• Durability and Quality: Built with high-quality materials for long-lasting performance and resilience in various operational conditions.
