459-645 nm nominal rejection-region broadband notch filter (P12607)

P12607 is a broadband notch filter. Its measured curve has a low-transmission region at approximately 471-615 nm, with transmission recovering on either side. Choose it for broad spectral suppression rather than assuming a narrow laser-line stop.

Optical performance

  • Measured wavelength range: 380-780 nm. Performance outside this measured interval is not established by this curve.
  • Selected regions at or above 80% transmission: 380-452 nm; 652-780 nm. Approximate measured intervals.
  • Selected regions at or below 5% transmission: 471-615 nm. Measured sample intervals; confirm the required blocking for your order.
  • Peak transmission: Approximately 95.6% at 665 nm. Peak wavelength is not the same as a defined centre wavelength.
  • Measured edge at 50% transmission: Approximately 457.0 nm. Interpolated absolute-transmission crossing, checked against the factory summary.
  • Measured edge at 50% transmission: Approximately 642.4 nm. Interpolated absolute-transmission crossing, checked against the factory summary.
  • Customization: We can customize stock and sample-book designs. Tell us the wavelength response, size and operating conditions you need.

These values come from the measured samples and help you choose a starting design. We will agree the final specification for your order. Custom versions have their own specifications and measured curves.

Applications to consider

  • Broadband illumination shaping: Consider suppressing the indicated wavelength region while retaining shorter and longer wavelengths. Check that the desired signal lies outside the transition bands.
  • Spectral contrast development: Evaluate whether reducing the rejected band improves contrast for a selected source and detector. Compare both remaining transmission regions with detector sensitivity.
  • Multi-region optical experiments: Consider retaining light on both sides of the rejection band. Add channel-separation optics if independent measurements are required.

Choosing this filter

  • Additional regions reach at least 50% transmission at approximately 380-456 nm. Include these in the detector and blocking assessment.
  • Check the full wavelength range of your light source, the wavelengths your detector responds to, and how much unwanted light you need to block. Use the full curve when choosing a filter; the product code and peak do not tell the whole story.
  • Tell us the angle at which light reaches the filter and whether the beam is parallel or converging. For demanding rejection or high-power use, confirm the required blocking and power-handling specifications.

Custom options

Start with this stock or sample-book design, then tell us what you need to change. We can discuss the wavelength bands, transmission, blocking, angle, glass material, size and operating conditions with you, and agree a specification for your custom filter.

Transmission spectrum

Questions about P12607

Which part of the spectrum is most useful when choosing P12607?

The measured regions at or above 80% transmission are 380-452 nm; 652-780 nm. They are measured intervals, not guaranteed passband tolerances. Compare the full curve with the signal wavelengths you need to retain.

What should I check beyond the main transmission region of P12607?

For P12607, additional regions reach at least 50% transmission at approximately 380-456 nm. If your detector responds there, include that light in the background assessment or discuss an additional blocking requirement.
