Stemi 508 HD Ball Bearing Boom Stereo Microscope
Stemi 508 HD Ball Bearing Boom Stereo Microscope
The Stemi 508 stereo microscope is Apochromatic with 8:1 zoom ratio providing excellent image contrast and color accuracy. The apochromatic optics provide superior images, while the smooth movement of the ball bearing boom stand allows for viewing larger samples with ease.
Viewing Head: 35º inclined ergonomic Greenough stereo microscope body. Viewing head rotates 360°. Interpupillary distance adjustment from 55mm - 75mm. Trinocular body has photo port 50/50 division and includes 0.5x c-mount adapter.
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: Ball bearing boom stand with large square base measuring 5mm (11.2") x 260mm (10.2") x 32mm (1.3") with weight of 22 kgs (49lbs). Maximum distance from the vertical post to the end of the base is 235mm (9.3"). Outside diameter of vertical post is 37mm and has a locking ring.. Vertical post is 380mm (15") tall, a 225mm (8.9") extension post can be added. The two horizontal posts have a 20mm OD with smooth ball bearing movement. Each pole is 570mm (22.4") long from end to end.
Working Distance: 92mm
Focusing: Includes pin mount coarse focusing holder.
Illumination: 4-Quadrant LED ring illuminator with 72 LED lights.
Camera: Includes 0.5x c-mount adapter and 4K HD camera with HDMI and USB2 output. 1/1.8" Exmor/STARVIS Sony IMX678(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).
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.
