Does the tetrahedral shape of the tip give any influence to AFM images?
No matter what shape of a tip has a possibility of giving marks to AFM images. Some triangle marks might appear in the image with the tetrahedral tip. • What is the deviation of mechanical properties of the OMCL-AC series cantilever? Stiffness and resonant frequency of each cantilever in the data sheet are calculated values. Please allow the deviation of plus/minus 20 % on the resonant frequency, plus75% and minus 50% on the stiffness. • What is the light reflectance of the silicon cantilever without the reflect coating? It is about 25% for the visible light. Even with such small reflectance, non coated cantilever (OMCL-AC160BN-) will work in most of the AFM instruments available in the market. So, choose OMCL-AC160BN- if you care the backside coating material (Aluminum). • Does the infrared light pass through the silicon cantilever tip? Yes. Silicon (non-dope) with the thickness of about 1mm shows transparency of about 50% for the IR light of 1.2 um – 8 um. IR light in that range can
