Product Family Description

  • Multiple Configurations for Video/Photo/Visual Applications
  • 3X Greater Magnification than Other Coaxial In-line Systems
  • Highest Possible Long-Distance Resolution
  • Focus from Infinity to 55mm
  • Supplementary Focuser Available for CentriTel™ Capabilities

Recognized as the standard in Long-Distance microscopes, the K2 DistaMax™ now incorporates a patent-pending IVS focus system, further improving what was already a top performer, and making the K2 DistaMax™ easier to use than previous models. To begin using the K2 DistaMax™, simply choose an objective for the front and a camera mount for the rear.

The K2 DistaMax™ offers high magnifications and a dynamic working distance range, covering all sensors up to 35mm (43mm diagonal) formats. The K2 DistaMax™ Single-Port package includes a manual iris for light level and depth of field control. The Dual-Port package includes a right angle mirror for switching between views (not simultaneous viewing), in addition to the parts included in the Single-Port package. The K2 DistaMax™ is ideal for applications ranging from remote vacuum chamber viewing to on-line process control.

The NWE Objective allows focus from infinity to as near as 675mm. Perhaps the most versatile K2 DistaMax™ objective, the NWE also can be used with the Microscope Objective Adapter Disc and other accessories. All objectives attach directly to a front dovetail. When combined with NWE Objective, Microscope Objective Adapter Disc, and Objective Adapter, the K2 DistaMax™ can interface common infinity-corrected microscope objectives, even when the Coaxial In-line Illuminator is used, making it a powerful direct coaxial in-line system. To enable CentriTel® for all formats simply add the CentiTel® Focuser, #87-430. For viewing through an eyepiece (not included), adapter #58-796 is required.
