ToupTek – universal C-mount adapters for microscopes and telescopes (23.2 / 31.75 mm)

Name: ToupTek – universal C-mount adapters for microscopes and telescopes (23.2 / 31.75 mm)
Brand: ToupTek
SKU: 17977

Universal C-mount adapters from ToupTek connect cameras to microscopes (23.2 mm eyepiece port) and telescopes (31.75 mm). Available in focus-adjustable (parfocal) and fixed versions, with 0.37×/0.5×/0.75×/1× magnification selected to match the sensor size.

Why an adapter and which magnification to choose?

The adapter matches the intermediate image field of the microscope/telescope to the camera sensor size and provides the mechanical C-mount connection. A smaller sensor requires lower magnification (e.g. 0.37×), a larger one requires higher (0.75×/1×). Adjustable versions let you achieve parfocality with the eyepiece.
