294nm UV Bandpass Filter FWHM 10nm

The 294 nm bandpass filter is engineered to selectively transmit ultraviolet (UV) light around 294 nanometers, offering precise wavelength control with a Full Width at Half Maximum (FWHM) of 10 nanometers. This filter is designed to provide clear and focused transmission within a specific spectral range, while effectively blocking wavelengths outside this range.

Coligh offers 294nm 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:

• Central Wavelength: 294 nm. The filter is optimized to transmit light centered at this UV wavelength, making it ideal for applications that require specific light isolation around 294 nm.
• Bandwidth (FWHM): 10 nm. The FWHM of 10 nanometers indicates the filter’s ability to transmit light within a 10 nm bandwidth centered on 294 nm. Transmission is reduced to half of its maximum value at wavelengths 5 nm on either side of the central wavelength (i.e., 289 nm and 299 nm), defining the filter’s effective passband.
• High Optical Density: Outside the passband, the filter features high optical density, ensuring that wavelengths beyond the 294 nm ±5 nm range are effectively blocked. This characteristic minimizes spectral interference and enhances the accuracy of UV measurements.
• Applications: This filter is ideal for use in UV spectroscopy, fluorescence studies, photochemical reactions, and other scientific and industrial applications where precise control of UV light at 294 nm is essential. It supports accurate wavelength-specific measurements and enhances signal clarity.
• Construction: The filter is constructed from premium optical materials with advanced coatings to ensure high transmission efficiency and durability. It can be mounted in various optical systems, including spectrometers, microscopes, and other analytical instruments.
• Performance: Designed with sharp cut-on and cut-off characteristics, the filter provides precise wavelength selection and minimal distortion, ensuring that only the desired UV light around 294 nm is transmitted.

The 294 nm bandpass filter with a 10 nm FWHM is a crucial optical component for applications requiring accurate UV light isolation and measurement in the 294 nm range, offering reliability and precision for a range of scientific and industrial uses.
