3.What is BP410-40nm Bandpass Filter？
A BP410-40nm Bandpass Filter is a violet and near-ultraviolet bandpass optical filter. It selectively transmits light within the spectrum of 390-430nm violet light, and strongly blocks deep ultraviolet, other visible light and infrared stray light outside the designated passband.
4.What is typical application for 410nm Bandpass Filter?
Typical application for 410nm Bandpass Filters are very broad, including biochemical fluorescence detection & fluorescence microscopy, ultraviolet spectrum analysis instruments, industrial UV defect inspection and UV light sensing, environmental optical monitoring and medical diagnostic equipment, 400–420 nm near-UV laser auxiliary filtering systems.
5.What is key parameter when choose for right Bandpass Filters?
When selecting a bandpass filters, the center wavelength (CWL) will be one of key parameter to be designated, it refer to the central wavelength at stable passband. Secondly, Peak and Average Transmittance is equal and more than 90% typically, higher transmittance might need Anti-reflective(AR) coating. Third, Full Width at Half Maximum (FWHM), it refer to the passband at 50% transmittance rate in between. Forth, Blocking Range & Depth. Fifth, substrate material, e.g., ultra clear glass, quartz glass, color filter glass. Additionally, considering physical and environmental specifications such as dimensions, thickness, surface quality, and environmental stability, as these factors are equally important.
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. Liyuan optoelectronics have been focus on optical coating for more than 17 years and offer one-stop optical filters solution including Narrow Bandpass Filters, IR cut-off Filters, Longpass & Short Filters, Notch Filters, ND filters, Star filters and Optical sapphire block.
Other typical Bandpass filters in stock from Liyuan Optoelectronics include BP810 BP820 BP830 BP840 BP850 BP860 BP870 BP880 BP890 BP…etc.
