Is a dedicated BSE detector truly necessary for BSE only SEM imaging?

Hey EM aficionados! How many times have you heard someone (incorrectly) claim that the only way to collect a backscattered electron (BSE) image when SEM imaging is by using a "dedicated" BSE detector (typically annular in shape and sitting right below the SEM polepiece)? I (sadly) hear this all the time, even from people who consider themselves highly proficient (or even expert level) in SEM. Well, in this raw, unedited, unfiltered, uncensored, and uncut video (ha ha), I'm here to put this myth to rest once and for all by showing you how to use your plain, old, boring Everhart-Thornley detector (ETD) to effectively collect BSE (only) images. Along the way, I'll cover the pros and cons of BSE imaging using an ETD compared to a dedicated BSE detector (spoiler, the ETD has more advantages than you might think), why "secondary" electron (SE) mode for the ETD is incorrectly labelled and should be called "Secondary + Backscattered", compare SE+BSE and BSE SEM images at 2 and 10 kV, and discuss the additional considerations when operating in immersion (ultra-high resolution) mode when using the "through lens" detector. Immediately after this video, I proceed to performing SEM-EDS mapping using EDAX APEX, which may be found here:    • SEM-EDS mapping using EDAX Octane Elite ED...   Thank you for your support, my fellow EM aficionados (as we close in on 5,000 subscribers)! Please like, subscribe, and share and leave any questions or comments you may have and I will do my best to reply as soon as possible. Video topic requests are always welcome and appreciated; I enjoy making these videos and wish I could make them more frequently, but the demands of my job make it tough to do so; I’m in charge of three S/TEMs, two dual FIB/SEM systems (another to be added later this year), and half of an SEM and this keeps me very busy!
