Longpass Filters

O01506Longpass Filters

O01506 is a longpass filter. A high-transmission region is shown at approximately 548-780 nm. Consider it when you need to pass longer wavelengths and reduce shorter-wavelength light within the measured range.

  • Product family: Longpass Filters
  • Measured wavelength range: 380–780 nm
  • Published response: Transmittance

Measured interval is not the passband. Values shown are sample measurements. Final specifications are agreed for your order.

OPTICAL PERFORMANCE · O01506

Read the numbers.
Understand the response.

Measured wavelength range

380-780 nm. Performance outside this measured interval is not established by this curve.

Selected regions at or above 80% transmission

548-780 nm. Approximate measured intervals.

Selected regions at or below 5% transmission

394-520 nm. Measured sample intervals; confirm the required blocking for your order.

Peak transmission

Approximately 95.7% at 733 nm. Peak wavelength is not the same as a defined centre wavelength.

Measured edge at 50% transmission

Approximately 540.2 nm. Interpolated absolute-transmission crossing, checked against the factory summary.

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.

OPERATING CONDITIONS

Match the complete optical system.

Match the full source band.

Compare the source emission spectrum with the filter curve. Include the source bandwidth, rather than relying on the nominal wavelength alone.

Check unwanted response.

Compare the complete measured response with your detector sensitivity. Confirm any additional blocking needed for your system.

Define the incidence conditions.

Specify the working angle and whether the beam is collimated or converging. Confirm the required response under those conditions.

Confirm the physical fit.

Provide the available mounting space, required shape, dimensions and thickness. Physical specifications will be confirmed for your assembly.
