Collection: UV Optical Bandpass Filter (193nm - 400nm)

Covers the ultraviolet (UV) and near-UV spectrum (193–400nm), characterized by high photon energy and strong interaction with organic materials, enabling precise wavelength isolation for sensitive applications.

• Application 1: In spectroscopy, it filters out unwanted wavelengths to isolate UV signals for accurate analysis of chemical compounds, such as measuring absorbance in UV-Vis spectrophotometers to determine molecular concentrations.
• Application 2: In semiconductor lithography, it blocks extraneous light while transmitting 193nm (ArF laser) or other critical UV wavelengths, ensuring precise pattern transfer onto photoresist during microchip manufacturing for high-resolution circuit fabrication.
• Application 3: In fluorescence microscopy, it separates excitation light (e.g., 365nm) from emitted fluorescence signals, allowing clear imaging of UV-excited biomarkers in biological samples by rejecting background noise and enhancing contrast.
