540nm Optical Notch Filter FWHM 30nm
540nm Optical Notch Filter FWHM 30nm is a notch filter that use to transmite the light of 500-520nm and 580-600nm. It also attenuate the light between 530nm to 565nm. Coligh supplies standard notch filter and custom notch filters for laser applications which need to block laser light.
- Hard coating to ensure endured life
- High optical density OD>3 for blocking region
- high pass band transmission >90%
540nm Optical Notch Filter FWHM 30nm Description
The 540/30nm optical notch filter is a high-performance band-stop filter. It is widely used in laser fluorescence instruments and biomedical laser systems through its ultra-hard coating durability, ultra-high blocking ability (OD>3) and excellent high passband transmittance (>90%). It helps analysts screen accurate light signals and low-noise imaging.
- We use hard coating technology, which has a very long service life and ensures the stability of experimental results
- In the range of 530-565nm, there is a high stopband cutoff depth OD>3, which can block the stray light of the target wavelength. In addition, the transmittance in the passband is greater than 90%, which can maximize the transmitted signal. For example, in fluorescence imaging, non-target fluorescence signals near 540nm can be isolated to ensure that the signals in multi-color fluorescence experiments do not interfere with each other, while maintaining a high signal-to-noise ratio.

540nm Optical Notch Filter FWHM 30nm Applications
The 540nm Optical Notch Filter FWHM 30nm is mainly used in the following applications due to its ultra-high OD blocking, narrow bandpass and high durability:
- Quantitative analysis of fluorescent proteins In multi-color fluorescence sorting, GFP and tdTomato fluorophores can be detected simultaneously to reduce crosstalk between channels
- Raman spectroscopy The 540nm/30nmn notch filter can help the Raman spectrometer exclude fluorescence and scattered light near 540nm, and improve the signal-to-noise ratio of the full peak
- Agricultural monitoring The 540nm optical notch filter can filter out the 540nm scattered light in the ambient light, separate the optical signal of the 540nm band that reflects the vegetation health index, and analyze the health status of farmland
- Laser system Using a 540nm negative filter in the laser system can effectively eliminate laser noise, ensure the purity of the laser output, and improve the laser beam quality.
