Detent: Click stops at 0.63x, 0.65x, 0.8x, 1x, 1.25x, 1.6x, 2x, 2.5x, 3.2x, 4x, 5x for repeatable measuring.
Eyepieces: Includes widefield 10x / 23mm focusing eyepieces. Eyepieces accept 26mm diameter reticle.
Objective Lenses: Zoom range of 0.63x - 5x.
Zoom Ratio: 8:1
Total Magnification: 6.3x - 50x. For alternate magnifications eyepieces can be changed and auxiliary lens added to stereo microscope. View magnification chart below for options. Maximum resolution 225 Lp/mm - 2.2µm.
Stand: Boom Stand with square base. Horizontal post is 20.9" long, vertical post is 15" tall. A 8.9" extension post is available. Vertical post has a locking ring. Base dimensions are 11.2" x 32". Weight 48lb.

Camera: Includes 0.5x c-mount adapter and 4K HD camera with HDMI and USB2 output. 1/1.8" Exmore Sony IMX334(C) sensor. Pixels 2.0 x 2.0µm. 30 frames per second at 3840 x 2160 HDMI. Binning 1x1. 8mp image capture, software, power adapter 100~240V, HDMI Cable, SD Card, USB Mouse. Includes software for PC with USB connection for image capture. Software can be used to capture images and video and make measurements. If making measurements with the software you will need a stage micrometer (available below).
LCD HD Monitor: 13.3" LCD HDMI monitor, true 1080P. LED backlight. Monitor mounts directly to HD camera. Includes 110~240V power cord and HDMI cable.
Software Calibration: If you plan to make measurements using the software you will need to calibrate the microscope. Calibrating your software with the microscope requires use of a stage micrometer. When ordering please select this option if you do not already have a stage micrometer. The stage micrometer included is a dual ruler with 1" equally spaced and numbered 0-10 as well as 25mm equally spaced and numbered 0-25. If NIST certification is selected 10 points in total will be certified. Please note that NIST certification takes approximately 2 weeks.
Warranty: 1 year.
