Neutral Density (ND) Filter - Absorptive 50% Transmission, 425-675nm - MidOpt ND030 Size:27mm The MidOpt LP920 Near-Infrared (IR)

The MidOpt LP920 Near-Infrared (IR) Longpass Filter blocks visible (VIS) and unwanted near-IR wavelengths and is designed for use with 940nm LED illumination

The MidOpt LP900 Near-Infrared (IR) Longpass Filter sharply blocks light below 900nm while allowing longer wavelengths to pass

The MidOpt SP713 Extended Hot Mirror (Reflects Near-Infrared (IR) Up To 1300nm) is designed for applications where full spectrum IR (heat) and / or ultraviolet (UV) radiation are an issue

1550nm light is also generally considered to be “eye safe” (and safe for CMOS camera sensors)

Neutral Density (ND) Filter - Absorptive 50% Transmission, 425-675nm - MidOpt ND030 Size:27mm The MidOpt LP920 Near-Infrared (IR)The MidOpt ND030 Neutral Density (ND) Filter has an optical density of 0. 3, or average 50% transmission across the visible (VIS) spectrum. The ND030 has identical male and female threads on either end so it can be stacked with other ND filters to achieve various optical densities. For example, two ND030 filters stacked together would perform approximately the same as one ND060 Filter. MidOpt ND Filters are double side polished for exceptional
