About Ronja Benchpress

This is a Ronja model that is not a communication device, but a bench for measuring lens properties.

You insert a combination of LED and lens into the bench and measure exact transmitter gain of the lens+LED combination in decibels. You can then use this value to calculate precise range of the device.

This is handy for evaluating new types of LEDs, new types of lenses or if you have doubts if your lens is of adequate quality for the device (for example due to greenish haze).
