500nm Optical Bandpass Filter FWHM 40nm
Item No: COBF500-40
Type: Bandpass optical filters
Coating: Hard coating
A 500nm bandpass filter with a Full Width at Half Maximum (FWHM) of 40nm would have its peak transmission centered at 500nm with a width of 40nm.
500nm bandpass filter with a FWHM of 40nm, light within the range of approximately 480nm to 520nm would be transmitted with significant efficiency, while light outside this range would be significantly attenuated.
The precise wavelength selection provided by a bandpass filter with a narrow FWHM like 40nm can significantly enhance the performance and accuracy of various optical systems and instruments across a wide range of applications. It can be widely used in:
- Photolithography
- Fluorescence Microscopy
- Spectroscopy
- Environmental Monitoring
- Optical Communication
