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 go through the silicon cantilever and/or tip (OMCL-AC160BN-: non-coat cantilever) because the cantilever and tip are thin. • Does OLYMPUS have highly doped silicon cantilevers? I am interested in STM/AFM simultaneous measurement. It’s not available, however OLYMPUS offers a platinum-deposited probe; OMCL-AC240TM- as its alternative. Silicon tip cantilevers in OMCL-AC series are made of n-type single crystal silicon lightly doped with phosphorus that is a semiconductor material and the tip surface is covered with natural o
