Microscope
245 (C Collins;
student microscope; c. 1880)
Charles Collins produced microscopes
and other optical apparatus from 1863 until the early 1900s. The census of
spring, 1861, listed the 23-year-old Charles as an optician, living with his
parents in Croydon, Surrey. Collins appears to have opened his independent
retail shop and factory in 1863 in downtown London, and joined the Quekett
Microscopical Club in 1865, and the Royal Microscopical Society in 1866.
Hogg’s sixth edition of The Microscope, in 1867, featured several of
Charles Collins’ instruments, including a binocular student’s microscope and
the Bockett lamp. Later, monocular versions of the student’s microscope were
also manufactured. At the beginning of 1871, Charles moved his retail shop to
Great Portland Street, about a two-minute walk from his former store. Charles
Collins’ business shows signs of decline by the early 1890s. The 1911 census
recorded Charles Collins as being an “optician, sight testing, spectacles”,
suggesting that his business at that time had primarily been reduced to
fitting eyeglasses. Microscope 245 is a monocular version of the Collins’
student microscope and can be dated to c. 1880. The microscope is signed ‘C.
Collins, Optician, 157 Gt. Portland St., London’ on the base. Coarse
focus is by rack and pinion, and fine focus by a wheel on top of the limb.
The finish is lacquered brass and black oxidized brass on the base and limb.
Collins made the tube of these microscopes uncommonly large in diameter, so
that eyepieces from all his microscopes would be interchangeable.
