Neutral Density, Polarizing, and IR Block

Our filters are designed to work with a wide variety of lighting: monochromatic or white LED, fiber optic, structured diode-generated patterns and other lighting commonly used in machine vision applications. We stock a broad range of filter options designed to quickly and securely mount to the smaller diameter lenses used by CCD and CMOS cameras.

Polarizing
PR032 Rotating Linear Polarizer with locking screw – reduces glare in the visible spectrum;
PC052 Circular Polarizer – reduces glare; for autofocus or autoiris lenses; for visible spectrum applications
PI035 IR Linear Polarizer – reduces only infrared glare
Neutral Density Filters
ND030 Optical Density = 0.3 (T = 50%) – reduces light intensity
ND060 OD = 0.6 (T = 25%) – reduces light intensity
ND090 OD = 0.9 (T = 12.5%) – reduces light intensity
ND120 OD = 1.2 (T = 6.3%) – for viewing into lamps
NI030 Optical Density = 0.3 (50%) – reduces light intensity
NI060 OD = 0.6 (25%) – reduces light intensity
NI090 OD = 0.9 (12.5%) – reduces light intensity
NI120 OD = 1.2 (6.3%) – for viewing into lamps, furnaces, welding processes, etc
IR Block – Visible Pass
BP550 NIR-UV Block/Visible Pass – 400-700nm … all color applications where filtering is not provided with the camera’s sensor
SP645 Mid-Red/NIR Dichrioc Block – best IR/mid-red block
SP675 Deep Red/NIR Dichrioc Block – best IR/deep red block
SP700 Hot Mirror/NIR Dichroic Block – standard IR block, for use with monochrome cameras
SP705 Deep Red/NIR Block – Alternate Recommendation: SP700 or SP730
SP730 Hot Mirror/NIR Colorless Block – standard IR blocking, for use with color cameras
SP785 IR Dichroic Block (modified)

UV & IR Pass Filters

MidOpt’s machine vision filters increase the contrast of the subject under inspection, improving the ability of the system 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 and continue to work to control your lighting in the long run.
