Eyepiece lenses (Short name : OCD)

Measure scope eyepiece lenses, OC.WFD10×(OCD10×) and OC.WFD20×(OCD20×) can all be fitted with φ 24 micrometer glass. The diopter correction function allows the scale marks to be focused to match the operator’s vision. Also, an optional eyepiece hood is vailable to cut ambient light and improve visibility and reduce eye fatigue.

How to use the traveling micrometer lens : OSM-MF

The traveling micrometer lens magnification has 10x magnification, with a scale comprising eight 8 mm divisions and a movable indicator line. The movable indicator line has X shaped crosshairs formed of two vertical lines, and can be moved to the right or left by rotating the handle on the right.
One turn of the handle moves the crosshairs 1 mm, or 100 scales (1 mm is 100 increments). This scale can be used to read the degree of movement. Connection is possible with MF and MFS series only, and the unit is ideal for detailed measurement.

Relay Lens C-Mount Adapter RL-CA

Relay Lens C-Mount Adapter RL-CA
Simple application in image observation

【Two models available for OCD10x and OCD20x】

The C-Mount Adapter can be mounted directly over the eyepiece lens of the microscope, allowing the eyepiece micrometer to be shown on the monitor. Though there are some limitations on field of vision, scale marks can be displayed to allow measurement and positioning on the screen. Select after referring to the image data guide table.

* Because the image is magnified electronically, by camera, etc., the field of vision displayed on the monitor becomes narrower in comparison with observation through a microscope with the naked eye. Also, the range of the scale marks displayed on the monitor is limited, as illustrated.
(In the case of a 2/3 inch camera, vertical 43 increments, horizontal 58 increments)

Direct Lens C-Mount Adapter  D-CA Simple application in image observation

【Two models available for Φ20 and Φ30】

The Direct C-Mount Adapter can be mounted directly onto the lens, after removing the eyepiece. Its low cost means that it can be used for simple inspections where the work-piece only needs to be displayed on a monitor. Select after referring to the image data guide table.

* Because the image is magnified electronically, by camera, etc., the field of vision displayed on the monitor becomes narrower in comparison with observation through a microscope with the naked eye.
