Affordable and practical, the 400-TBL-10-2 Stereo Microscope is one of National Optical & Scientific Instruments' most popular models. Featuring a pared down yet rugged design, the 400-TBL-2 sets itself apart from the other models in the 400 series with paired 2x objectives, high intensity incidental and transmitted tungsten illumination, and 2 80mm stage plates.
Much like its cohort, the 400-TBL-10-2 features the same vertical paired 10x widefield eyepieces. The eyepieces boast diopter adjustment, interpupillary adjustment, and allow for an optional reticle to be attached. Illumination is controlled via an illuminated base mounted on/off switch. And rack and pinion focusing with safety mechanisms ensure that you can adjust the view of the specimen according to your needs.

adjustment from 50mm to 75mm. Accepts optional #965-400-05 &
