What is 800nm bandpass filters?
An 800nm bandpass filter is a precision optical element that selectively transmits light centered at 800 nm (near-infrared, NIR) and blocks all wavelengths outside its passband.
What is typical application for 800nm bandpass filters?
Typical application for 800nm bandpass filters is very broad, including near-infrared sensing and detection, laser signal filtering & laser equipment, industrial machine vision & inspection, biometric recognition devices, spectral analysis instruments.
What is key parameter when choose for right bandpass filter?
When selecting Bandpass Filters, you need to consider the following key factors. First and foremost, center wavelength accuracy, which determines the ability to screen specific wavelengths of light. Secondly, full width at half maximum (FWHM), which defines the wavelength range allowed to pass through. Thirdly, transmittance requirements, reflecting the transmission efficiency for target wavelengths. Fourth, blocking depth and range, indicating the ability to block non-target wavelengths. Fifth, angle of incidence (AOI), which affects filter performance. Finally, substrate and physical specifications — common substrate materials include K9/BK7, fused silica, and others.
