Highlights Ni200 Neutral density filters can be used to reduce the amount of light reaching the camera to about 1% transmission, thus allowing longer exposure times that result in reduced depth of field. This improves the separation of subject matter from the foreground and/or background. These filters include identical male and female threads on either … Continued
Ni120 Neutral density filters can be used to reduce the amount of light reaching the camera to about 6.25% transmission, thus allowing longer exposure times that result in reduced depth of field. This improves the separation of subject matter from the foreground and/or background. These filters include identical male and female threads on either end … Continued
Ni090 filters exhibit uniform attenuation over the entire visible and near-IR range that most industrial CCD/CMOS cameras are sensitive within. The actual percent transmission averages a nearly constant 12.5%, while reflectivity in the visible portion of the spectrum averages 30%. These filters include identical male and female threads on either end so that they can … Continued
Ni060 filters are used to restrict visible and/or near-IR light, reducing the amount reaching the camera sensor, thus allowing for longer exposure times and reduced depth of field. This technique can improve the separation of subject matter from the background. Ni060 transmission is approximately 25% while reflected light averages about 20% over the 400-1100nm wavelength range. These … Continued
Ni030 filters feature uniform attenuation simultaneously over the visible and near-IR range that is imaged by most industrial CCD/CMOS cameras. That is, regardless of wavelength within this range, approximately 50% of the light will be transmitted while less than 10% will be reflected back towards the source or subject. These filters include identical male and … Continued
