Protecting Art from Light's Damaging Rays: The Role of UV Light Meters
Ever wondered how museums keep their precious artworks looking vibrant for centuries? One secret weapon is the UV light meter. This handy tool helps conservators monitor and minimize exposure to light, the biggest culprit behind art damage.
Why is UV light so harmful? It's the invisible part of sunlight and artificial light that packs the most damaging punch. Think of it as the aggressor slowly fading colors and weakening materials.
Here's where UV light meters step in:
-
They measure:
-
The proportion of UV light present (µW/Lumen).
-
The total amount of UV radiation (µW/M²).
-
The amount of visible light (Lux).
-
The goal? Keep UV levels as low as possible, ideally below 20µW/M² or 75µW/Lumen. Normal museum lighting should also stay within the 150-250 Lux range.
-
Once you have the readings, you can take action!:
-
Adjust light levels to reduce exposure.
-
Install UV filters on display cases, windows, and fluorescent tubes for added protection.
Thinking about specific models? The UV light meter is a popular choice. It measures all the essential parameters (UV, visible light) and displays them clearly.
Need to track changes over time? Opt for the data logger model with its data logging capability. It stores over 70,000 readings and lets you easily export them for analysis. Plus, no fancy software needed – just a spreadsheet will do!
By using UV light meters, museums can ensure their treasures remain radiant for generations to come.
