Minus Green Filters

HMG-5Minus Green Filters

HMG-5 is a minus-green correction filter. It attenuates part of the green-to-yellow region relative to surrounding wavelengths. This can help reduce a green cast in lighting. Average transmission in the sample is 92.7% over 400-500 nm, 83.7% over 500-600 nm, 95.1% over 600-700 nm. The resulting light output also depends on the lamp spectrum.

Understand the response.

Measured wavelength range

380-800 nm. Performance outside this measured interval is not established by this curve.

400-500 nm

Approximately 92.7% average transmission; the range is 83.8-94.8% in the measured curve.

500-600 nm

Approximately 83.7% average transmission; the range is 77.2-94.1% in the measured curve.

600-700 nm

Approximately 95.1% average transmission; the range is 92.5-95.8% in the measured curve.

Measured edge at 85% transmission

Approximately 521.6 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.

Architectural & Museum Lighting

Color, glare and spectral control for built environments and exhibits.

Stage, Studio & Projection

Color, patterns and beam control for performance and projection.

Imaging & Photography

Manage exposure, unwanted wavelengths and reflection.

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