Basler Premium Lenses C125: Why do 1/2.5" Basler Lenses Often Fit Better than 2/3" Lenses?
Most lenses are designed for 2/3" sensors, which works perfectly fine for cameras equipped with a sensor of that size. In response to the trend towards smaller sensor sizes, Basler has developed lenses with a small image circle that matches the small surface of modern sensors. Basler Lenses are produced by Fujinon exclusively for Basler.
To best take advantage of their cost-optimized design for a multitude of applications, they are available in six different focal lengths:
- 4 mm
- 6 mm
- 8 mm
- 12 mm
- 16 mm
- 25 mm
The benefit of a smaller image circle is especially prominent with regards to resolution, thus:
Small sensor + lens with small image circle = the perfect combination!
