Beauty instrument LP490 Long pass filter
LP490nm longwave pass filter is an optical component used in optical beauty instruments. Its key feature is to allow light with a wavelength greater than 490nm to pass through, while blocking light with a wavelength less than or equal to 490nm from passing through. In beauty instruments, LP490 longwave pass filters are usually used for functions such as hair removal.
Applications of LP490nm longwave pass filter:
- Beauty instruments: Used in optical beauty devices, transmitting >490nm and blocking ≤490nm, typically for hair removal functions.
- Biological fluorescence imaging: Blocks short-wavelength excitation light and transmits only fluorescent emission, improving signal detection. Enables clearer visualization of fluorescent markers, allowing researchers to analyze biomolecule distribution, localization, and interactions.
- Optical instruments: Enables precise wavelength range selection for extracting and analyzing specific optical signals, essential in optical measurement, material testing, and scientific research.
