Measuring in the Dark
Instrument: Wndsn Enhanced Vision Night Ops Telemeter
For operation in poor lighting conditions, we have developed a Telemeter model made of acrylic glass with laser-engraved scales that are visible at different lighting levels -- the engraving changes the refractive index of the acrylic -- the scales appear light against a dark background when backlit and dark in front of you bright background, allowing the Telemeter to be used in a variety of adverse lighting conditions.
