IR-Block/Visible Optical Filters feature 25.4™ C-Mount for installation.
Available in SP635, SP644 and AB555, IR-Block/Visible Optical Filters come with C-Mount for easy installation. SP635 filters are A/R coated on both sides and offer ≥90% peak transmission. Used in cameras with CMOS sensor responsivity, SP644 is used in 395-638 nm range. Having laser protection at 1064 nm, AB555 comes with 3.5 mm thickness and has optical density of UV (190-375nm), near-IR...

Optical Filters are suitable in aerial vegetative monitoring.
Available in standard threaded mount to fit any camera size, Optical Filters are available in 0.5mm, 1.1mm and 2.0mm thicknesses. Modifying single color camera by removing IR blocking filter, Bi725 Red Edge Bandpass Filter allows reflected near-infrared light (850nm) and green light (550nm) to capture camera sensor’s in red channel and green channel. TB550/660/850 and TB475/550/850 filters...

Suited for imaging at 350-1,100 nm wavelengths, low-reflectivity NI Filters come in 4 optical densities of 0.3, 0.6, 0.9, and 1.2 with overall transmission of 50, 25, 12.5, and 6.25%, respectively. Units feature uniform attenuation simultaneously over entire visible and near-IR range imaged by most industrial CCD/CMOS cameras. Available in 1, 2, and 3 mm thicknesses, filters have...
