Collins Compound Student Microscope

Title

Description

The student monocular microscope is manufactured by Charles Collins. Made from brass, the compound microscope is engraved on the modified Crouch-style foot: "C. Collins Optician 157 Gt Portland St London." Collins designed the tube of these microscopes to be uncommonly large in diameter so that eyepieces from all his microscopes could be interchangeable. The microscope has concave mirror, coarse and fine focus as well as a substage stop wheel. Collins' microscopes were good quality, reasonably priced equipment that were considered inferior to high-priced makers such as Powell and Lealand, or Ross. However, this would not effect Collins' popularity as his market were mainly amateurs, students and medical professionals.

Condition:

Cosmetically: The brass lacquer has some marks and strains from use. There are age marks present on the mirror.
Mechanically: The pivot joints are tight and functioning. The coarse and fine focus is functional.
Optically: The lenses are clear and functional.
