When working with any camera that has been modified and its internal IR cut filter removed, a SP635 filter mounted on the front of the lens, when desired, can restore functionality to the camera like the unmodified camera. This is an absorptive infrared rejection filter, recommended for protecting a camera’s sensor from stray light emitted by lasers or other high-power near-IR light sources. SP635 filters are A\/R-coated on both sides to maximize visible-band transmission while providing superior out-of-band blocking.\u003c\/p\u003e\n\u003cp\u003eAll MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003cdiv style=\"margin-top: 20px;\"\u003e\n\u003ch3 class=\"card__title heading h3\"\u003eTechnical Specifications\u003c\/h3\u003e\n    \u003cdiv class=\"collapsible-section\" style=\"margin: 20px 0;
