Midwest Optical : ND400
Description
The Midwest Optical ND400 Neutral Density Filters reduce light intensity in the visible spectrum without affecting color and contrast. ND filters can also be used with monochrome and color cameras in the visible spectrum.
Available Models Include:
| ND400-25.4 |
| ND400-13.25 |
| ND400-22.5 |
| ND400-25.5 |
| ND400-27 |
| ND400-30.5 |
| ND400-34 |
| ND400-35.5 |
| ND400-37 |
| ND400-37.5 |
| ND400-40.5 |
| ND400-43 |
| ND400-46 |
| ND400-49 |
| ND400-52 |
| ND400-55 |
| ND400-58 |
| ND400-62 |
| ND400-67 |
| ND400-72 |
| ND400-77 |
| ND400-82 |
| ND400-86 |
| ND400-95 |
| ND400-105 |
Features
• Different optical densities (ODs) equate to an overall decrease in luminous transmission (see chart below)
• Mounted ND filters can be stacked to test various optical densities
• Achieve shallow depth of field
• Reduce over-saturation in high heat environments (Ex. Hot molten metal and welding applications)
