BPF Series THz and IR Band Pass Filters from Lake Shore

Lake Shore’s BPF Series band pass filters are specifically designed for applications where precision and dependability are paramount, especially when used in extreme environments. Over 100 standard models include four common aperture sizes and over 25 center wavelengths (CWLs) spanning from 10 to 590 µm (about 500 GHz to 30 THz), making these filters readily available to researchers who want to avoid custom engineering charges and get on with their work without delay.

Features and capabilities

• Precision frequency selective surfaces (FSS) for high spectral resolution
• Narrow pass bands with excellent transmission
• Pure gold filter element for best results in thermal cycling and gamma radiation conditions
• Designed for use in cryostats and adjacent to cooled detectors
• Compact and lightweight
• Superior performance with “stacked” configurations
• Temperature stable and radiation tolerant
• Three year warranty
