XENON-SAPPHIRE 3.2/96MM 25-1076451 16K Macro Lens System 16k High Resolution Lens with Retro Positioning

Description

The Schneider Optics Xenon-Sapphire 3.2/96 (p/n: 25-1071189, 25-1076451) high-resolution, high-speed lens is optimized for use with 16k pixel line scan sensors. It is broadband coated and can be used in the range of 400 – 1000 nm. The V-mount makes the  Xenon-Sapphire 3.2/96  easy to install and rotate into the desired azimuth position for a wide range of high resolution applications where existing 12k lenses (with approximately 5 µm pixel sizes) are not sufficient anymore.

The 25-1076451 is a mechanically adapted version in order to be used in retro orientation; the adapted version of Xenon-Sapphire 3.2/96 can be used for 12K as well as 16K systems

The XENON Sapphire 3.2/96 provides three significant stop positions that are especially marked on the stop ring: 

• F#3.2 is the maximum opening of the stop and provides maximum brightness. The mechanical vignetting at this F/number is approx. 20% at the edge of the field (approx 10% for the adapted version). The MTF for 100 lp/mm is very high up to the edge of a 58 mm field. Due to the high aperture the lens is more sensitive with respect to change of magnification.
• F#4.2 shows maximum MTF and practically diffraction limited performance over the whole field. The depth of field is bigger but the lens is still sensitive to magnification changes. At 4.2 the lens is free of artificial vignetting.
• F#4.6 produces more diffraction which reduces the MTF slightly but is now extremely homogenous over the entire field. The lens shows this performance for the complete magnification range from -0.53 < ß’ < -0.47 and performs well for a magnification range of -0.55 < ß’ < -0.45 at a 16k performance of 100 lp/mm.
• For the adapted version: F#4.2 and 4.6 show a very homogeneous MTF and practically diffraction limited performance over the whole field of 82 mm. The depth of field is bigger and the lens is quite insensitive to magnification changes within -1.85 < ß’ < -2.15. At 4.2 the lens is free of artificial vignetting.
