What is 465nm Narrow Bandpass Filter?
A 465nm Narrow Bandpass Filter with 10nm FWHM is an optical interference filter designed to transmit light within a narrow spectral window centered at 465nm while blocking all other wavelengths from the ultraviolet through the near-infrared . The “10nm FWHM” indicates the bandwidth at 50% of peak transmission, making this a precision narrow bandpass filter for applications requiring high spectral selectivity.
What is typical application for 465nm narrow bandpass filters?
Typical application for 465nm bandpass filters are very broad, include Fluorescence Microscopy & Biomedical Imaging, Raman Spectroscopy, Flow Cytometry, Machine Vision & Industrial Inspection, Laser Line Isolation & Cleanup, Optical Sensing & Instrumentation, DNA Analysis & PCR, etc.
What is key parameter when choose for right 465nm narrow bandpass filter?
When selecting 460nm narrow bandpass filters, the center wavelength (CWL) will be one of key parameter to be designated. Secondly, Full Width at Half Maximum(FWHM), the width of the passband measured at 50% of peak transmission. Third, peak transmittance, depending on coating quality and grade. Forth, blocking depth, the ability to suppress out-of-band stray light. Fifth, Coating Technology & Durability. Sixth, surface quality, etc. Seventh, substrate material, e.g., float glass, fused silica, borosilicate glass, etc.
Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical technology that apply depositing nanomaterials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which coating layer is firm and has good tightness, and small bandwidth drift.
Other typical Bandpass filters in stock from Liyuan Optoelectronics include BP810 BP820 BP830 BP840 BP850 BP860 BP870 BP880 BP890 BP…etc.
