Salient Features

Neutral Density Filter – Low Reflectivity 50% Transmission 

Ni030 filters feature uniform attenuation simultaneously over the visible and near-IR range that is imaged by most industrial CCD/CMOS cameras. That is, regardless of wavelength within this range, approximately 50% of the light will be transmitted while less than 10% will be reflected back towards the source or subject. These filters include identical male and female threads on either end so that they can be stacked with other ND filters to achieve various optical densities.

Ni030 Neutral Density Filter – Low Reflectivity 50% Transmission MidOpt_Ni030_Trans_Graphic

  • Useful Range : 400-1100nm
  • Optical Density : 0.3
  • Transmission: 50%
  • Tolerance : +/- 5.00%
  • Surface Quality : 40/20

The performance of a filter is based on what happens to light passing through the filter. The apparent color of light reflected off the surface is not a reliable way to judge the filter’s capabilities. Batch-to-batch difference in the apparent color of the coatings or filter substrates can often be easily seen when looking at two examples of the same filter type. The color of the coating does not indicate a disparity in performance.

Slip Mount

  • Designed for varifocal lenses, wide angle lenses and lenses without filter threads
  • Accommodates standard threaded mounts
  • Low profile and oversize diameter design prevents wide angle lens vignetting
  • Locking set screws and a wrench are provided to secure the adapter to the lens
  • Many varifocal and shorter fixed focal length (wide angle) lenses are not supplied with filter threads due to the presence of a protruding, strongly convex lens element. Our slip mount adapters allow standard threaded filters to be fitted securely to these and a large variety of lenses that do not have filter threads provided.

Ordering Example:

  • Filter: BP470
  • Outside Diameter of Lens in mm: 43mm

Correct Part# is:

  • BP470-S43

C/CS Camera Mount

midopt-c-mount

  • Designed to thread directly into any C/CS mount camera between the lens and sensor
  • Wrenching slots aid in threading the filter into the camera body. A wrench is supplied with each filter.
  • Helpful in applications with space constraints
  • Can be used with wide angle lenses that do not accept filters at the front end to prevent vignetting
  • C/CS mount filters are available in a standard 1mm thickness

Ordering Example: 

  • Filter: BP470
  • Mount Size: 25.4

Correct Part# is:

  • BP470-25.4

 Unmounted  & Custom Size

midopt-unmounted

  • Any MidOpt filter type can be provided as an Unmounted filter
  • Custom shapes and sizes are typically fabricated with one day to two week lead times
  • Custom filter types with longer lead times can also be quoted. Please contact us regarding feasibility.
