Yes—if your signal sits at 940 nm and you need visible and shorter-wavelength suppression. OPTOStokes specifies the LP940 at 940–1100 nm average transmission >90%, 350–925 nm blocking at T < 1%, 1.1 mm thickness, and 60/40 surface quality. The page calls out LiDAR and range finding, machine vision, biometric systems, and IR detector protection as core uses. That makes the LP940 a practical front-end edge filter when you want better contrast and lower solar or visible contamination in 940 nm systems. OPTOStokes also offers off-the-shelf prototypes, rapid OEM support, custom sizing, CNC shaping, and mounting ring options, which helps buyers move from lab validation to production hardware without switching platforms.
