Customers and industry standards specify test light levels. Unfortunately, achieving the right lighting conditions is tricky and tedious. Using handheld light meters is difficult because of the chance of casting shadows and altering the lighting. Mounting a light meter near the test chart is better, but limits you to a reading at a single point – you still don’t know the lighting uniformity. Even with multiple meters, measuring flatness and average light level is hard. Isolight solves all the problems entirely.
Isolight uses innovative LED indicator rings around each light sensor to show when the light level is too high, too low, or within target levels. Users set their target light level in lux and uniformity in either lux or percent.
