Filters

As a provider of machine vision components, Voltrium Systems also provides a wide range of filters such as bandpass, dual bandpass, longpass, shortpass/nir cut, polarizing, neutral density, protective, color balancing.

Bandpass Filters are the simplest, quickest and most cost-effective way to improve the image contrast, repeatability, and long term stability of any industrial vision system.

Dual Bandpass Filters are ideal for applications that use a color camera during the day and IR illumination at night – ensuring that clear, accurate images are acquired under all lighting conditions.

Longpass filters let longer visible and/or infrared wavelengths pass while blocking shorter wavelengths of light. Mainly for use in monochrome (black and white) imaging applications, they can help to improve contrast, resolution and separate colors while maximizing brightness of surroundings in the vicinity of the subject under inspection or surveillance.

Shortpass filters are useful for improving contrast, resolution and separating colors in black and white or color applications.

Polarizing filters reduce unwanted reflection or specular glare and can also be used to check stress patterns in transparent glass and plastic.

Sunglasses for your system, ND filters reduce light intensity without affecting apparent color. They also allow for longer exposure times and reduced depth of field by using a wider iris opening, thus improving the separation of subject matter from background information.

Available in glass or acrylic substrates, protective filters shield lenses and lighting from impact, dust and harsh environments – while blocking shorter UV wavelengths.

Corrects apparent color and contrast introduced by artificial white lighting, restoring natural colors. Used to modify the color balance in LED, fluorescent, halogen, metal halide, tungsten, and other white lighting, making colors appear more natural.
