Today I experimented with LEDs on the OCP. I first drilled a 5mm hole at 90 degrees to and just short of the lens bore, then drilled a 5mm hole from the base and parallel with the lens bore until it met up with the first so forming an inverted L shape. With the LED in place the light shines on the work rather than the acrylic Lens. In the picture without the LED the cross hairs on the acrylic rod aren’t discernible but with the LED on the cross hairs light up.
I did try shining the LED at the lens at differing heights but with little to no effect With the LED pointing down onto the work the cross hairs appear to light up. I tried different coloured LEDs but only the red has this effect.
Sorry for the low quality photos, but it’s nigh on impossible to get both the rings at top and the crosshairs below in focus.
