Millilambert

Definition

The Millilambert is a unit of luminance equal to one-thousandth of a lambert (0.001 lambert). It provides a more convenient way to express moderate luminance values using the lambert system, making calculations and specifications more manageable.

History/Origin

This unit was developed as a practical alternative to the full lambert unit when dealing with moderate luminance values. The milli- prefix makes it easier to work with typical luminance levels without using very large or very small numbers in the lambert system.

Current Use

Used in specialized photometric applications where the lambert system is preferred. Common in certain technical contexts and applications where traditional photometric units are still used or required for compatibility with existing measurement systems.

Watt per Square Centimeter Steradian (at 555 nm)

W/(cm²·sr)

Definition

The Watt per Square Centimeter Steradian at 555 nm is a radiometric unit of luminance that measures radiant power per unit area and solid angle at the peak sensitivity wavelength of the human eye. It is used for precise photometric calculations and laser applications.

History/Origin

This unit was developed for applications requiring precise conversion between radiometric and photometric quantities. The 555 nm wavelength corresponds to the peak sensitivity of the human eye, making it ideal for accurate photometric measurements and laser safety calculations.

Current Use

Used in laser safety, precision photometry, and applications requiring exact conversion between radiometric and photometric units. Essential for laser power measurements, optical system design, and safety calculations where precise luminance values are critical.
