Context

Period: c.1860
Canada: Used in one of the Departments of Queen's University, Kingston, Ont.
Function: To observe biological specimens in minute detail. / .8 wellaston camera lucida is an accessory which employs a reflection prism or mirror to cast a duplicate image of an objective onto a plane surface so that an outline of the object can be traced. (ref. 1, pg. 108; ref. 2, pg. 346)
Technical: Wenham introduced his beam splitting prism in 1861 for use in a binocular microscope. This resulted in one tube straight & one inclined. Wenham microscopes were popular for the rest of the century because the prism could be removed to restore monocular vision, important for use at higher powers & resolution (ref.1,pg73-74)
