Bandpass Filters for Argon Laser Applications
Bandpass filters for argon laser applications are designed to transmit selected argon-ion laser emission lines—most commonly 488nm or 514.5nm—while reducing unwanted out-of-band light, secondary laser lines, and plasma tube glow. By isolating a specific wavelength from a multi-line argon laser output, these filters provide a targeted optical excitation source for analytical and imaging instrumentation.
Applications:
- Laser line cleanup in optical setups for isolating primary argon emissions while blocking secondary lines and plasma glow
- Fluorescence microscopy and flow cytometry for providing a targeted excitation band for fluorophores such as FITC and GFP
- Holography and Raman spectroscopy for isolating a single spectral laser line to prevent optical interference
