What Is This Tool?
This converter transforms luminance values measured in blondel, an outdated photometric unit, into lumen per square centimetre per steradian, a modern unit used in precise optical and photometric applications.
How to Use This Tool?
- Enter the luminance value in blondel into the input field
- Select blondel as the source unit and lumen/sq. cm/steradian as the target unit
- Initiate the conversion to obtain the equivalent luminance in lumen/sq. cm/steradian
Key Features
- Converts luminance from the historical blondel unit to lumen/sq. cm/steradian accurately
- Supports applications in lighting engineering, photometry, and optical design
- Bridges obsolete measurements with modern standard units for consistent data comparison
- Web-based and easy to use without requiring complex calculations
Examples
- 10 blondel converts to 0.00031831 lumen/sq. cm/steradian
- 0.5 blondel converts to 0.0000159155 lumen/sq. cm/steradian
Common Use Cases
- Interpreting and converting historical luminance data recorded in blondel
- Calculating brightness levels for micro-LED or OLED pixels using precise photometric units
- Designing and measuring luminance in optical systems and illumination devices
- Calibrating luminance meters for high-intensity or small-area light sources
Tips & Best Practices
- Ensure accurate input values in blondel for reliable conversion results
- Understand the obsolete nature of blondel and handle historical data with care
- Use the converted lumen/sq. cm/steradian values for detailed brightness assessment in modern applications
- Maintain unit context to avoid confusion due to the very small conversion factor
Limitations
- Blondel is an outdated unit primarily relevant to historical measurement data
- Careful interpretation is required when comparing blondel values with modern luminance units
- Large numerical differences caused by the small conversion factor demand attention to precision and unit context
Frequently Asked Questions
- What is a blondel unit?
- Blondel is an obsolete unit of luminance named after André Blondel, used historically in photometry for measuring brightness per area.
- Why convert blondel to lumen/sq. cm/steradian?
- Converting blondel to lumen/sq. cm/steradian helps interpret old data using modern units crucial for precise optical and lighting applications.
- How do the units relate in physical terms?
- Lumen/sq. cm/steradian quantifies luminous flux per unit area and solid angle, effectively representing brightness on a small scale.
- Can I use this tool for current standard luminance values?
- This tool is mainly for converting historical blondel data; modern measurements typically use candela per square metre or lumen/sq. cm/steradian.
Key Terminology
- Blondel
- An obsolete unit of luminance once used in early 20th-century photometry, now replaced by SI units.
- Lumen/sq. cm/steradian
- A modern photometric unit measuring luminous flux per unit area per steradian to characterize brightness on a small scale.
- Luminance
- A measure of luminous intensity per unit area indicating the brightness of a surface.
