Manufactured OD 6.0 Notch Filter

 

  What is an OD 6.0 notch filter?

OD 6.0 Notch Filter is an ideal optical choice that can achieve strong light suppression within a specific narrow wavelength range.

While it maintains high transmittance in other wavelength bands.

Among them, an OD value of 6.0 indicates extremely strong attenuation ability in the blocking wavelength band, equivalent to a transmittance of less than 0.0001%.

It effectively blocks light of a specific wavelength.

• OD 6.0 Laser Wavelength Suppression: 355 to 1064 nm
• Very suitable for laser-based Raman, fluorescence and biomedical systems

Characteristics of OD 6.0 notch filter

• Ultra-High Rejection

When the optical density in the target wavelength band reaches OD 6.0, it can effectively eliminate laser lines or interference signals.

• High Transmission

The transmission rate of the notch filter is usually greater than 85%.

• Narrow Band Rejection

With a narrow bandwidth, it can precisely match laser wavelengths such as 532 nm, 633 nm, 785 nm, and 1064 nm.

• High Stability

Using high-precision multi-layer dielectric coating technology, it can withstand high-power lasers and maintains stable performance over a long period of time.

Chenyu OD 6.0 Notch Filters feature deep blocking with broad transmission bands that are ideal for use in laser analysis applications where specific wavelengths need to be blocked in order to maximize system performance.

They can be used various situations.

 Applications:

• Raman Spectroscopy

Effectively filter out the excitation laser and retain only the weak Raman signal.

• Fluorescence Microscopy

Remove the excitation light to enhance the image signal-to-noise ratio and contrast.

• Laser Systems

The filter can block the laser wavelength.

• Medical Imaging

Eliminate background light and enhance the sensitivity of fluorescence detection.
