Description:
In improved cavity radiometer, each sensor cone ends in small tube so that black paint cannot form truncating meniscus. Inner diameter of tube is 0.25 mm; its outer diameter is 0.5 mm. During painting process, excess paint is drawn out through tube, preventing formation of meniscus at apex. After paint is cured, end of tube is crimped shut to form effective light trap.
