The OM2300S zoom stereo microscope head has become our de facto, 'Go To' head for our industrial inspection customers. Upgraded in 2010, but with no increase in price, the 2300S provides a solid design with crisp, clean optics beyond our expectations at this price level. The 7X-45X zoom range (6.4:1) is parfocal with dual diopters integrated into the oculars. Standard working distance is 4.5" which increases to 6.5" with the addition of 0.5x auxiliary barlow lens. Three alternative barlows are available: 0.75x, 1.5x and 2.0x. WF10X eyepieces and eyeguards are included.

The microscope is available in both binocular or trinocular format. A 23mm photo tube is included with the trinocular.

Lifetime Limited Warranty.

Requires Focus Block: OMFB23S. For the V3 stereo stand, this microscope head requires Focus Block: OMFB23SV3.
