MidOpt SP Series – VIS Pass Filter SP510

Uniforce Product

Salient Features

Blue Shortpass Filter

Passes blue light while blocking the green and red portions of the spectrum. SP510 filters are useful for improving contrast and resolution, and separating colors in black and white or color applications, as when separating gold metallic finishes from silver metallic finishes.

SP510 Blue Shortpass Filter MidOpt_SP510_Trans_Graphic

  • Useful Range : 340-500nm
  • Cut-off Wavelength 50% T : 510nm
  • Tolerance : +/- 10nm
  • Minimum Peak Transmission : ≥90%
  • 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
