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.
