3) Overlay of two images is poor
Observations & likely cause
• If the split control is turned the wrong way, image quality can be affected.
• Split control should always be turned ANTI-CLOCKWISE (i.e. this moves the two images apart)
for the best split results.
Resolution
• Identify which is the reflected (shorter wavelength) image by following the flow-chart below.
• Always turn the split control anti-clockwise to separate the two images when using a standard
OptoSplit II (please note, for the OptoSplit II bypass we recommend a clockwise split).
