VanGuard 1131ZL Binocular and 1132ZL Trinocular Zoom Stereo Microscopes with LED upper and lower illumination feature a zoom magnification range of 7.5X to 34X (with supplied 10X eyepieces). The precision stereo optics produce high-resolution, three-dimensional images. Additional, optional eyepieces are available to customize for specific magnification requirements.
- Illumination:
- Upper (Incident): variable LED light source for maximum light.
- Lower (transmitted): variable LED light source. 1A, 250V fuse.
- Illumination Switch: Separate illumination switches allow the upper and lower illumination to be on separately or simultaneously.
- Viewing Head: Binocular or trinocular heads are inclined at 45°. Features interpupillary and dioptric adjustments, a large field of view, and a 90mm working distance.
- Included Eyepieces: 10X Widefield (DIN) with a field number of 20. Field number refers to the diameter (in mm) of the fixed diaphragm within the eyepiece.
- Zoom Optics:The 0.75X to 3.4X primary magnification produces a nominal total magnification range of 7.5X to 34X, when the 10X eyepieces are used. Features smooth-turning, dual side-mounted zoom controls.
- Focusing Movement: Large, knurled knobs drive rack and pinion mechanism for easy, controlled focusing. Also features a slip clutch mechanism to protect the gears, tension control, and 85mm of total vertical travel.
- Stage Plate: Frosted glass stage plate and black/white reversible stage plates come standard.
- Stage Clips: Locked-on, stainless steel spring-loaded stage clips.
- Base: Stable 245 x 205mm base fitted with anti-skid rubber feet.
