Home Products Precision Optics Precision Optical Filters Ultra Narrow Bandpass Filters ULTRA NARROW BANDPASS FILTERS Our bandpass filters are custom-designed to meet your individual requirements. Achieving the narrowest possible Bandwidth (FWHM) with our ultra narrow bandpass filter for a wide variety of spectroscopic & laser-based applications. We offer filters with bandwidth at Full Width Half Maximum (FWHM) selectable from Wideband to Ultra-Narrowband, for use in the ultraviolet, visible or infrared spectral regions. CONTACT US! Designing ultra narrow bandpass filters to optimize performance. THE MATERION ADVANTAGE Our filters demonstrate a high signal-to-noise performance characteristic which makes them desirable for maintaining optimal transmission. Manufactured to customer specifications User-specified wavelength range for blocking Environmentally durable Deep Blocking Density (OD 6) within blocking wavelength range Low thermal coefficient which results in thermal spectral stability of CWL For your most challenging applications in: Plasma Spectroscopy, Nuclear Fusion Plasma Diagnostics, Atmospheric Plasma Diagnostics, Solar & Stellar Astronomy, Lidar, ASE Suppression, Deep-space Optical Telecommunications and others.
