Neutral density (ND) filters are used to attenuate incident radiation without altering its spectral distribution. The neutral density value of an ND filter is related to the transmittance by:
D=Log(1/T)
Optical Density: D
Transmittance: T
Absorption glass ND Filter :
Materials | Optical Neutral Density Glass |
| Fltness | 2l per 25 mm |
Surface Quality | 80/50 |
Parallelism | 3' |
| Dimension | circle (dia.25.4mm typical) or square |
| Dimension Tolerance | +/-0.2mm |
| Optical Density Tolerance | ±5% /10 |
Metallic Coated Neutral Density Filter :
Metallic coated ND filters are glass or quartz substrates with a precision metallic coating (Inconel) that provides uniform attenuation across a wide spectral range.
