I'm looking for detailed quotes for Scanning Electron Microscopes (SEM). Please provide your best pricing options along with specs, lead times, and any warranty information. It's important to know about the different models you offer and their key features. Also, I'd appreciate it if you could include any available accessories or additional options that might enhance the SEM performance. Let me know if there's a possibility for bulk discounts or financing options, as this will help in making a decision. Thanks!
