Description

The MidOpt SP651-25.5 is a near-infrared blocking filter designed to pass near-UV and visible light from 350-645 nm while effectively blocking near-IR radiation from 650 – 1050 nm. This filter also blocks UV transmission below 350nm. CCD/CMOS imagers that need to pass near-UV AND visible wavelengths can utilize these filters to block near-IR light while preventing a reddish, washed-out color in the final image. Used at normal incidence, these filters can also be placed in front of some UV-transmitting arc lamps to limit the amount of near-IR radiation (heat) that might damage any subject under illumination. Although the SP651 substrate is bubble-free UV-grade fused silica, it is possible that some sort of additional mechanical cooling of the area around this hot mirror may be important, depending on the wattage of the lamp that is being used.

All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
