Hot Mirror & UV-IR Cut Filters

HM-730UV / IR Cut-off Filters

HM-730 is a visible-pass / infrared-attenuating filter. The main high-transmission region is approximately 388-714 nm. It can be considered when visible light is required and part of the longer-wavelength spectrum needs attenuation.

  • Product family: UV / IR Cut-off Filters
  • Measured wavelength range: 300–1200 nm
  • Published response: Transmittance

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

OPTICAL PERFORMANCE · HM-730

Read the numbers.
Understand the response.

Measured wavelength range

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

Selected regions at or above 80% transmission

388-714 nm. Approximate measured intervals.

Selected regions at or below 5% transmission

300-362 nm. Measured sample intervals; confirm the required blocking for your order.

Peak transmission

Approximately 95.1% at 661 nm. Peak wavelength is not the same as a defined centre wavelength.

Average measured transmission, 400-700 nm

93.611%. Calculated from the factory sample data.

Average measured transmission, 750-1000 nm

13.200%. Calculated from the factory sample data.

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.

Imaging & Photography

Manage exposure, unwanted wavelengths and reflection.
