🤔️Do you know Bandpass filters🪞are very common in our daily life?
They can be found in medical imaging, water 💦quality testing, night vision🎑…etc optical device or systems…etc.
Bandpass optical filters are designed to select a specific band of wavelengths passing and block undesired wavelengths.
Bandpass filters from Liyuan Optoelectronics have advantages of
• Bandwidth lower to 5nm.
• High transmittance over 90% or higher
• Deep cutoff depth
• High cost-effective narrow-band filter
