Neutral Density (ND) Filter - Absorptive 0.01% Transmission, 425-675nm - MidOpt ND400 ND The MidOpt LP830 Near-Infrared (IR)

The MidOpt LP830 Near-Infrared (IR) Longpass Filter is designed for use with an infrared LED light emitting at 850nm or 880nm

light from deeper UV excitation sources and deep red and near-IR (NIR) wavelengths

Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths and are anti-reflection (AR) coated to limit glare and minimize reflection loss

Neutral Density (ND) Filter - Absorptive 0.01% Transmission, 425-675nm - MidOpt ND400 ND The MidOpt LP830 Near-Infrared (IR)The MidOpt ND400 Neutral Density (ND) Filter has an optical density of 4. 0, or average 0. 01% transmission across the visible (VIS) spectrum. The ND400 has identical male and female threads on either end so it can be stacked with other ND filters to achieve various optical densities. Because the glass substrate is absorbing 99. 9% of the light that passes into the filter, these filters are not recommended for use with lasers or immediately in front
