Vintage Laboratory Microscope Illuminator — Adjustable Iris & Intensity, Tilting Stand, British, c.1950s–1960s

A thoroughly striking piece of British laboratory equipment — a vintage adjustable illuminator originally used as an auxiliary light source for microscopy, dating from the 1950s–1960s. Beautifully constructed in the tradition of mid-century scientific instrument making, with a black enamel body, brass fittings, and a fully adjustable stand that tilts and swivels to direct the beam precisely. The combination of adjustable iris diaphragm and variable intensity control makes this a genuinely sophisticated piece of optical equipment — and an extraordinarily characterful object for interior, display, or prop use. Fully working.

Note: This lamp runs on 240v (UK mains). The existing cord and plug are functional but could benefit from rewiring to a more aesthetically pleasing period-style cord — a straightforward job for an electrician. Please see photos for full condition detail. Age-related wear consistent with former laboratory use.

Condition

• Function: Fully working.
• Body & base: Good condition for age — some specks of colour loss and wear on the black enamel base and lamp body (see photos).
• Brass: Slightly tarnished — consistent with age, patina adds to character.
• Bulb access: Via the round grip on the rear of the lamp head.
• Cord & plug: Functional — could benefit from aesthetic rewiring.

Specification & Provenance

• Origin: British, c.1950s–1960s — made in the UK during the golden era of British precision scientific instrument manufacturing.
• Stand: Fully adjustable — tilts and swivels to direct light at any angle.
• Iris diaphragm: Adjustable — controls the diameter of the light beam.
• Intensity control: Variable light level via main control box.
• Voltage: 240v (UK mains).
• Dimensions: Approx. 20cm across the lamp head; approx. 28cm tall with lamp at the top of the stand at right angles to base.
• Weight: Reasonably heavy — solid and stable construction.
• Appeal: An exceptional and rare piece of mid-century British laboratory design — equally at home in a cabinet of curiosities, a design-led interior, a film or television production, or a scientific instrument collection. The adjustable iris alone makes it a conversation piece.
