Accesories and lens for the filters

These filters, combined with our lighting systems, provide better results in vision applications. Machine vision filters increase the contrast of the subject under inspection, improving the system ability to distinguish desired characteristics. Increased contrast allows for increased accuracy and speed. Because lighting will change over time and ambient light is everywhere, our filters create the contrast you need to continue working and controling your lighting in the long run.

Filter selection is made by fiting the optical filter in the lighting type and diameter sizing of the camera lens.

LENS FILTERS

BAND PASS

These filters allow you to selectively control what your camera sees and are ideal for LED or laser diode use.

Far more rugged, thinner, less angle-sensitive, with much higher transmission and far lower in cost compared to conventional interference filters, they greatly improve contrast and eliminate the need for a costly light shroud.

LONG PASS

Long pass filters let longer visible and infrared wavelengths pass while blocking the shorter ones.

Useful for improving contrast, resolution and separating colors in black/white or color applications. Unless blocking of multiple wavelengths is necessary, is not recommended for machine vision.

SHORT PASS

Short pass filters let shorter (bluer) visible and infrared wavelengths pass while blocking the longer ones.

Useful for improving contrast, resolution and separating colors in black/white or color applications. Unless blocking of multiple wavelengths is necessary, is not recommended for machine vision.

POLARIZING

Neutral gray laminated glass filters transmit visible light in only one polarization plane and are used to suppress glare from specular surfaces.

Available from stock are linear, circular and infrared polarizers in most sizes.

NEUTRAL DENSITY

ND/NI filters are used to reduce luminous intensity without affecting color.

Different optical densities (ODs) equate to an overall decrease in luminous transmission. Other optical densities are available on request.

WHITE LIGHT BALANCING

These filters correct artificial white lighting so colors appear more natural.

They also reduce blue shading often strongly dominant in white LED lighting. Lighting is one way, very useful eliminating brightness. They must be used with a polarized lighting source and have fixing screws for avoiding loosen.
