1064nm Optical Narrow Bandpass Filter FWHM 10nm Description
1064nm Bandpass Filter FWHM 10nm is an optical narrow bandpass filter optimize design for 1064nm laser system.
- Central wavelength 1064+/-2nm, matching the wavelength output by ND:YAG laser, fiber laser and other light sources
- Half bandwidth 10+/-2nm, high transmittance at 1059-1069nm, narrow band design, effectively isolates adjacent wavelength interference.
- The transmittance in the passband is greater than or equal to 90%, and the 1064nm signal can pass efficiently.
- The cut-off band from ultraviolet to near infrared is 200-1700nm, and the ultra-long cut-off band OD4 cut-off depth

1064nm Bandpass Filter FWHM 10nm Applications
- Laser radar
The laser radar has weak echo signals in complex environments and is easily interfered with. 1064/10nm filter, OD4 cutoff depth cuts off background light and only receives 1064nm laser reflection signal. It can improve the accuracy of detection distance - Spectral analysis
In high-resolution spectrometers, weak signals need to be separated, but background noise masks the target spectrum. 1064nm/10nm narrowband filter can filter 1064nm excitation light and extract characteristic scattered signals. - Medical laser
Therapeutic lasers need to accurately target tissues to avoid damage to surrounding healthy tissues. This filter can filter out non-therapeutic wavelengths to ensure accurate focusing of 1064nm lasers and improve treatment efficiency - Fiber optic communication
Noise in fiber optic signals, Raman scattering, ASE noise, etc. reduce the communication signal-to-noise ratio. This filter can extract 1064nm signal light, suppress out-of-band noise, and improve data transmission stability.
