Features of the NL2 unit include:
- High output DC powered lamps provide up to 100watts of fluorescent lighting
- Ultra stable and reproducible lighting controlled by a precision colour corrected photo detector in a feedback circuit and a constant temperature ventilation system. The precision voltage reference, photo detector and lamps are temperature regulated to provide for maximum lamp stability and effeciency.
- 3.5 digit display indicator for readout of set point as sampled from the photo detector feed back circuit.
- A micro controller supports the analogue to digital converters providing an indication of lamp status and enable over current protection. it also supports diagnostic and service codes.
- Robust, welded aluminium chassis with stainless bezel and mitered diffuser supported glass frame.

Densitometry Tip
When looking for a desktop illuminator to use for densitometry measurements it is important to check the stability of the lightbox (ie, how much the intensity fluctuates)
Remember if your light source fluctuates 10% so do your measurements!
Our illuminators are tested for stability over a 12 hour period to ensure the fluctuation is within the limits we set.
