Multi-Bandpass Filters

MBP-A35Multi-Bandpass Filters

MBP-A35 is a multi-region spectral filter. The reference spectrum shows multiple high-transmission regions at approximately 541-559 nm; 644-671 nm; 827-871 nm. Light from these bands passes through the same optic. Check every band against your light source and detector. To measure the bands separately, use alternating light sources or separate detection paths.

  • Product family: Multi-Bandpass Filters

Understand the response.

Measured wavelength range

300-1200 nm. Performance outside this measured interval is not established by this curve.

Main band at half-peak transmission

Approximately 820.2-881.8 nm, giving a full width at half maximum (FWHM) of approximately 61.6 nm. This describes the main band only; other transmitted regions may remain.

Selected regions at or above 80% transmission

541-559 nm; 644-671 nm; 827-871 nm. Approximate measured intervals.

Selected regions at or below 5% transmission

321-524 nm; 573-631 nm; 693-806 nm; 903-1082 nm. Measured sample intervals; confirm the required blocking for your order.

Peak transmission

Approximately 96.5% at 845 nm. Peak wavelength is not the same as a defined centre wavelength.

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
