The MidOpt BN450-82 is commonly used in fluorescence applications with an emission range of 430 nm to 460 nm. It is suitable for use in LED or laser diode applications with higher- than-normal ambient lighting conditions and is less sensitive to variations in angle of incidence than traditional interference filters. The BN450 is an ideal filter for applications utilizing 450nm blue laser triangulation sensors. All MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.
