Shortpass Filters

C11514Shortpass Filters

C11514 is a shortpass filter. The main high-transmission region is approximately 394-563 nm. Consider it when you need to pass the shorter wavelengths used by your light source or detector. Check the longer-wavelength response as well as the main cut-off.

  • Product family: Shortpass 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 · C11514

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

394-563 nm. Approximate measured intervals.

Selected regions at or below 5% transmission

592-780 nm. Measured sample intervals; confirm the required blocking for your order.

Peak transmission

Approximately 95.9% at 544 nm. Peak wavelength is not the same as a defined centre wavelength.

Measured edge at 50% transmission

Approximately 570.5 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.

APPLICATIONS

Where this profile can help.

Industrial & Machine Vision

Inspection, detection, sorting and image contrast.

Imaging & Photography

Manage exposure, unwanted wavelengths and reflection.

Research & Instrumentation

Spectral selection, beam paths and measurement systems.

Stage, Studio & Projection

Color, patterns and beam control for performance and projection.

Application examples are starting points for evaluation; suitability depends on the complete optical system.
