What Is This Tool?
This converter transforms values from nox, a unit for very dim light levels, into watts per square centimeter at 555 nm, which measures radiant power per area for monochromatic green light at the photopic peak.
How to Use This Tool?
- Enter the value in nox representing low illuminance levels
- Select the target unit watt/sq. cm at 555 nm for radiant power per area
- Run the conversion to get the equivalent radiometric irradiance value
- Use the converted value for calibration, safety evaluation, or scientific measurement
Key Features
- Converts nox, a historical low illuminance unit, to radiometric watts/cm² at 555 nm
- Supports scientific, calibration, and lighting design applications involving very low light
- Based on the specific wavelength 555 nm relevant to human photopic vision peak
- Helps translate photometric illuminance into precise radiometric units
- Suitable for environmental, astronomical, and photobiological contexts
Examples
- 10 nox converts to 1.4641288433382e-9 watt/sq. cm at 555 nm
- 100 nox converts to 1.4641288433382e-8 watt/sq. cm at 555 nm
Common Use Cases
- Describing natural night illumination such as moonlight or starlight in astronomy
- Planning dark-sky environments and exterior lighting with very low background light
- Calibrating light sources and photometers for lighting design standards
- Conducting vision science experiments targeting the photopic sensitivity peak
- Setting safety limits and exposure levels for green optical sources in photobiology
Tips & Best Practices
- Always verify the wavelength is 555 nm since conversion depends on this specific value
- Use sensitive instruments to measure extremely low illuminance accurately
- Remember the nox unit applies primarily to very low light or near-dark conditions
- Consider the conversion as monochromatic and not suitable for broad-spectrum sources
- Apply the conversion carefully in photometric calibrations and scientific tests
Limitations
- Conversion applies only at 555 nm monochromatic wavelength, not broadband light
- Extremely low values may introduce measurement uncertainty requiring precision devices
- Not valid for other wavelengths or general illuminance units outside nox
- The conversion factor is fixed and should not be applied outside the specified context
Frequently Asked Questions
- What does one nox represent?
- One nox equals 0.001 lux and is used to quantify very low light levels.
- Why is 555 nm important in this conversion?
- 555 nm corresponds to the peak of the photopic luminous-efficiency function, relating radiometric and photometric units.
- Can this conversion be used for broad-spectrum light sources?
- No, it only applies to monochromatic light at 555 nm and is not valid for broadband illumination.
Key Terminology
- Nox
- An illuminance unit equal to 1 millilux, used for very low light levels like moonlight.
- Watt/sq. cm (at 555 nm)
- A measurement of radiant power per unit area at the 555 nm wavelength relevant to photopic vision.
- Illuminance
- The amount of luminous flux incident on a surface per unit area, measured in lux or nox for low levels.
