Viewing Head: 45º inclined Greenough stereo microscope body. Viewing head rotates 360°. Interpupillary distance adjustment from 55mm - 75mm. Trinocular microscope body with photo port 50/50 division to the left and integrated 0.5x c-mount adapter.
Detent: Click stops at 0.8x, 1x, 2x, 3x, 4x for repeatable measuring.
Eyepieces: Includes widefield 10x / 23mm focusing eyepieces. Eyepieces accept 26mm diameter reticle. 16x/14mm eyepieces are available and can be ordered below.
Objective Lenses: Zoom range of 0.8x - 4x.
Zoom Ratio: 5:1
Total Magnification: 8x - 40x. For alternate magnifications eyepieces can be changed and auxiliary lens added to stereo microscope. View magnification chart below for options. Maximum resolution 200 Lp/mm - 2.5µm.
Specimen Stage: Supplied with 84mm black and white stage plate and glass stage plate.
Stand: Track stand with built-in transmitted LED brightfield/darkfield illumination (adjust with lever on side of stand). Built-in near vertical illumination is controlled by stand. Working surface is 160mm W x 195mm D. Optional single spot illuminator or double spot illuminator can connect into stand.
Working Distance: 110mm.
Focusing: Coarse focusing.
Illumination: Integrated near vertical illumination, powered by stand, illumination angle 10º towards optical axis. If optional LED spot or dual spot is added, this light is height adjustable. Transmitted LED light provides both brightfield and darkfield illumination by adjusting a lever on the side of the base. Separate knobs control reflected / transmitted light for on, off, and dimming. 100~240V. Polarization is available for transmitted light base below.
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).
Monitor: 13.3" LCD HDMI monitor, true 1080P. LED backlight. Monitor mounts directly to the HD camera. Includes 110~240V power cord and short 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 will be certified. Please note that NIST certification takes approximately 2 weeks.
Size & Weight: 212mm (8.3") W x 370mm (14.6") D x 380mm (15") H, 12 lbs.
Warranty: 1 year.
