365nm带通滤光片

Use CWL 365 nm with 10–30 nm FWHM for most 365 nm UV LED systems that need a practical balance between LED output cleanup and usable UVA signal.

365 nm UV LEDs have broader emission than laser lines, so medium bandwidths such as 10 nm, 20 nm, or 30 nm are usually practical for source cleanup, UV inspection, fluorescence excitation, and exposure systems. Use 40 nm FWHM or wider when the setup needs more UVA output and can accept broader wavelength selection.

Use CWL 365 nm with 3–10 nm FWHM when isolating the mercury i-line from a mercury or mercury-xenon lamp source.

For mercury lamp systems, 365 nm is a real spectral line. A 3 nm or 10 nm FWHM filter is appropriate when the system needs stronger i-line selection. Use 20–40 nm FWHM when the setup can accept a wider UVA band and needs more transmitted signal.

Use CWL 365 nm with 10–30 nm FWHM to select a practical UVA band from xenon, deuterium, mercury-xenon, or other broadband UV sources.

For broadband UV illumination, the filter extracts a 365 nm-centered band from a wider spectrum. Use 10–20 nm FWHM for more defined wavelength selection. Use 30–40 nm FWHM or wider when the setup needs higher transmitted UVA signal for illumination, inspection, or detection.

Use CWL 365 nm with 20–50 nm FWHM for DAPI/Hoechst-type near-UV excitation channels when the fluorescence system is designed around 365 nm excitation.

For fluorescence microscopes or fluorescence detection systems, the 365 nm filter is usually placed on the excitation side before the sample. The emission-side filter should be centered at the actual blue emission band, not at 365 nm. Match the excitation filter with the light source, dichroic mirror, and emission filter set.

Use CWL 365 nm with 20–40 nm FWHM or wider for 365 nm curing, resin exposure, UV adhesive, coating, or i-line photoresist exposure systems.

For exposure applications, the filter defines the UVA irradiation band delivered to the material. Select the FWHM according to the lamp or LED spectrum, required irradiance, material sensitivity near 365 nm, and out-of-band blocking requirement.

Use CWL 365 nm with 3–20 nm FWHM before a UV-enhanced silicon photodiode, PMT, UV-sensitive spectrometer, or UV-capable camera when the target signal is near 365 nm.

For detector-side filtering, the filter should pass the 365 nm signal while reducing unwanted background outside the target band. Use 3–10 nm FWHM when stronger wavelength isolation is needed. Use 20 nm FWHM or wider when signal throughput is more important.
