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) |
