Holmarc’s Tool Maker’s microscopes are multipurpose measuring devices that are generally used for the examination and measurement of small mechanical and electrical parts or tools. These microscopes are used to view and measure linear distances, thread pitch, thread angles, tool edges, tool wear surfaces etc. and are ideal for photo-lithographic labs, nano-technology labs, and biomedical labs. These microscopes have a cross-hair reticle on the eyepiece that serves as a reference point for making measurements. The measurements are taken by moving the stages, which are equipped with precision micrometres with a resolution of 10microns (or 1 microns). The instrument uses high bright LEDs for both transmitted and flexible arm illuminations. Two objective -2X and 3X- as well as a 10X eyepiece are included with the systems. All the optical elements are coated with broadband multilayer AR fora clear and flare less images.
Holmarc offers three models of Tool maker’s microscopes; HO-TMM-01, HO-TMM-02, and HO-TMM-03. A 25mm x 25mm travel XY stage is used in the HO-TMM-01 mode, where as a 50mm x 50mm travel XY stage is provided in the HO-TMM-02 model. A rotating stage is also included in the HO-TMM-03 model in addition to the XY stage that are driven by digital micrometers with 1-micron resolution.Model | HO-TMM-01 | HO-TMM-02 | HO-TMM-03 |
