The UV mount lenses from Tōkyō Kōgaku were produced from the 1960's specifically for the Topcon Wink Mirror S and Topcon 100 Auto/Uni, and further used by the Unirex and the 1970s IC-1 Auto.

These unique lens designs do not have an aperture setting ring, as this is found on the camera body.

UV stands for Ultra Violet, as the lenses had a UV coating, and did not need a separate UV filter.

Later variants of standard lenses where marked Hi Topcor.

It appears that the standard lenses all had six elements.


  • UV Topcor 28mm f/4
  • UV Topcor 35mm f/3.5
  • UV Topcor 50mm f/2 [1]
  • UV Topcor 50mm f/2 (Hi Topcor)[2]
  • UV Topcor 50mm f/2.8 [3]
  • UV Topcor 53mm f/2 [4]
  • UV Topcor 55mm f/1.8 (Hi Topcor)[5]
  • UV Topcor 100mm f/4
  • UV Topcor 135mm f/4
  • UV Topcor 200mm f/4
