Entocentric Lens - VCH 1.4/25 - CC2514A-2M
Characteristics
- manually adjustable lens with fixed focal length for C and CS mount cameras
- for close-up imaging with 2 megapixel CCD and CMOS sensors
- sharp, high-resolution, high-contrast images from center to corners of the image
- extremely low distortion, suitable for image measurement
- increased light distribution
- Shortened MOD (Minimum Objective Distance) for even better close-up imaging without the need for distance rings
- compact design, robust and durable
- 3 fixing screws each (plus 2 knurling screws) for focus and iris - suitable for applications with vibrations and acceleration
