Applications for 830nm Bandpass Filter
Biomedical fluorescence: Some biomolecules, such as NADH and FAD, have fluorescence emission peaks around 830 nm when excited by near-UV light. A bandpass filter with a 830 nm CWL can block the excitation light and pass the emission light, enabling the detection and quantification of these molecules in biological samples.
Machine vision and imaging: 830 nm LEDs are commonly used for illumination in machine vision and imaging applications, such as barcode scanning, face recognition, iris scanning, and biometric security. A bandpass filter with a 830 nm CWL can block the ambient light and pass the reflected 830 nm LED light, enhancing the contrast and quality of the image
Laser diode cleanup: Some laser diodes have a broad spectrum of emission that can interfere with the desired wavelength. A bandpass filter with a 830 nm CWL can filter out the unwanted wavelengths and pass the 830 nm laser light, improving the spectral purity and the performance of the laser diode5
