The Tamron 23FM25L is a 2/3" high resolution fixed focal lens with lock and manual iris. Every optical aberration is thoroughly compensated for and as a result, high resolution is achieved from corner to corner. Furthermore, the 23FM25L is optically designed to achieve high quality performance even at minimum focusing distances.

High resolution is achieved by thoroughly compensating for aberrations and distortion, a critical requirement of image processing. In order to endure the vibration of factory automation apparatus, solid mechanisms are utilized. This makes it possible to maintain the finest quality even after long periods of use. Special versions of the lenses are available featuring lock mechanisms for the iris and focus making their use ideal in places suffering significant vibrations.

The 23FM25-L has a 25mm focal length and an iris range of F/1.6-16. The lenses feature an advanced mechanical construction that achieves a closer Minimum Object Distance (MOD). The MOD of the 50mm and 75m.m is just 0.5m and less than 0.3m for all the other lenses. Due to the greater focusing range, the lenses offer more coverage when they are used with the optional extension rings.

Tamron'’s compact lenses fit in the dimensional requirements of the machinery. The lenses that cover the most popular angles of view (8mm, 12mm, 16mm, 35mm, 25mm, 50mm, 75rnrn) each feature the same barrel diameter. All the lenses (excluding the 25FM65) have a uniform filter size of M255 P05. Available filters include a UV, Polarizer, Red, Green and Blue.
