ComPhysics CP-UV01<\/p>\n

Battery-free UV visualization for direct observation and relative comparison<\/h1>\n

The CP-UV01 is a passive optical UV indicator developed by ComPhysics. Suitable UVA\/UVB input produces a visible green response, allowing users to observe UV presence and compare relative transmission under controlled, repeatable conditions.<\/p>\n

What the CP-UV01 is\u2014and what it is not<\/h2>\n

The CP-UV01 uses passive optical wavelength conversion. It does not contain an electronic UV sensor, display, or battery. The visible green response is useful for visual indication and relative comparison, such as comparing two windows or lenses under the same UV source and geometry.<\/p>\n

It is not a calibrated UV radiometer.<\/strong> It does not report irradiance in W\/m\u00b2, UV Index, dose, or exposure limits, and must not replace certified medical, safety, occupational, or laboratory instruments.<\/p>\n

How it works<\/p>\n

Convert an invisible UV response into visible light<\/h2>\n

When suitable ultraviolet radiation reaches the CP-UV01 conversion structure, part of that input is emitted as visible green light. Response strength depends on wavelength, intensity, distance, angle, ambient light, and the material being tested.<\/p>\n

For meaningful comparisons, keep those conditions as consistent as possible and compare the visible response rather than treating it as an absolute measurement.<\/p>\n<\/div>\n

Complete Kit<\/p>\n

Observe directly or record with a smartphone<\/h2>\n

The Complete Kit combines the CP-UV01 body with the CP-UV01-SA smartphone adapter and a detachable light shield. The shield reduces ambient light near the viewing area; the adapter positions the device over a smartphone camera for recording and comparison with the free ComPhysics Green UV app.<\/p>\n
