    • 266 nm laser clean-up filter

    UV MaxLine laser-line filters provide the highest possible transmission level at a precisely defined laser line, while offering incredibly steep edges to eliminate optical noise from non-lasing (plasma) lines and spontaneous emission.

    Product features：Ultra-High Transmission: Maximum transmission at the laser wavelength, minimal loss；Extremely Steep Edges: Ultra-steep cutoff, sharp transition.；Effective Noise Rejection: Eliminates non-lasing line and spontaneous emission noise；Precise Wavelength Centering: Accurate center wavelength, locked to target laser line；High Damage Threshold: Withstands high-power UV lasers；Excellent Environmental Stability: Stable performance under temperature/humidity changes.

    Part Number：MP-LLF-266

    Application area：Ultraviolet Raman Spectroscopy | Laser Fluorescence Analysis Instruments | Confocal Microscopes | Semiconductor/Wafer Inspection
