BP970-50 대역 통과 필터(CWL=970nm, FWHM=50nm)

NIR Machine Vision & Surveillance

• Why: 970 nm is completely invisible to the human eye (unlike 850 nm, which has a faint red glow).
• Use Case: Covert surveillance or license plate recognition (ANPR) where "red glow" is undesirable.

Recommended Light Sources

• High-Power NIR LEDs (970 nm / 980 nm): This is the most common source for machine vision. Look for LEDs specified at 970 nm or 980 nm.
• Laser Diodes (975 nm / 980 nm): 975 nm and 980 nm are standard wavelengths for laser diodes (often used for pumping fiber lasers).
• Broadband Sources (Halogen / Tungsten): If using a broadband lamp, this filter is excellent because its OD5 blocking will successfully strip away all the visible and UV light, leaving only the 970 nm band. This is common in hyperspectral imaging setups.

Biomedical Imaging

• Use Case: Fluorescence microscopy or in vivo imaging where deep tissue penetration is required (NIR-II window entry), or identifying water-rich tissues vs. lipid-rich tissues.

Recommended Light Sources

• If your primary goal is Fluorescence (glowing markers), use an 808 nm Laser.
• If your primary goal is Structure/Water Mapping (native tissue contrast), use a 970 nm or 980 nm Laser/LED.
